DETAILED DESCRIPTION

In the optical communication technology, it is generally necessary to load information onto light and use the propagation of light to achieve information transmission, so as establish information transmission between information processing devices. In this regard, the light loaded with information is namely an optical signal. The optical signal is propagated in the information transmission devices, which may reduce loss of optical power and achieve high-speed, long-distance, and low-cost information transmission. The information that may be processed by the information processing device is an electrical signal. The information processing device generally includes an optical network unit (ONU), a gateway, a router, a switch, a mobile phone, a computer, a server, a tablet, a television and the like, and the information transmission device typically includes an optical fiber, a waveguide and the like.

Conversion of optical and electrical signals between the information processing device and the information transmission device may be achieved through the optical module. For example, an optical fiber may be connected to an optical signal input and/or output end of an optical module, and an optical network unit may be connected to an electrical signal input and/or output end of the optical module; a first optical signal from the optical fiber is transmitted to the optical module, which converts the first optical signal into a first electrical signal, and then transmits the first electrical signal to the optical network unit; a second electrical signal from the optical network unit is transmitted into the optical module, which converts the second electrical signal into a second optical signal, and then transmits the second optical signal to the optical fiber. Since information transmission between multiple information processing devices may be made via an electrical signal, at least one of the information processing devices needs to be directly connected to the optical module, and it is unnecessary for all of the information processing devices to be directly connected to the optical module. The information processing device directly connected to the optical module is called as a host computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module may be called as an optical port, and the electrical signal input end or the electrical signal output end of the optical module may be called as an electrical port.

FIG. 1 is a partial structural diagram of an optical communication system provided according to some embodiments of the present disclosure. As shown in FIG. 1, the optical communication system mainly includes a remote information processing device 1000, a local information processing device 2000, a host computer 100, an optical module 200, an external optical fiber 101, and a network cable 103.

One end of the external optical fiber 101 extends towards the remote information processing device 1000, while the other end thereof is coupled to the optical module 200 through the optical port of the optical module 200. An optical signal may undergo a total reflection in the optical fiber 101, and propagation of the optical signal in a total reflection direction can almost maintain the original optical power. The optical signal undergoes multiple total reflections in the optical fiber 101, such that the optical signal from the remote information processing device 1000 is transmitted into the optical module 200, or the optical signal from the optical module 200 is transmitted to the remote information processing device 1000, thereby achieving long-distance information transmission with low power loss.

The optical communication system may include one or more external optical fiber 101. The external optical fiber 101 may be detachably connected or fixedly connected to the optical module 200. The host computer 100 is configured to provide data signals to the optical module 200, receive data signals from the optical module 200, or monitor or control the working state of the optical module 200.

The host computer 100 includes a substantially rectangular housing and an optical module interface 102 disposed on the housing. The optical module interface 102 is configured to connect to the optical module 200 such that a unidirectional or bidirectional electrical signal connection is established between the host computer 100 and the optical module 200.

The host computer 100 includes an external electrical interface which may be coupled to the electrical signal network. For example, the external electrical interface includes a Universal Serial Bus (USB) interface or a network cable interface 104, and the network cable interface 104 is configured to be coupled by the network cable 103, thereby establishing a unidirectional/bidirectional electrical signal connection between the host computer 100 and the network cable 103. One end of the network cable 103 is connected to the local information processing device 2000, and the other end thereof is connected to the host computer 100, so as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. For example, a third electrical signal emitted by the local information processing device 2000 is transmitted to the host computer 100 through the network cable 103; the host computer 100 generates a second electrical signal based on the third electrical signal; the second electrical signal from the host computer 100 is transmitted to the optical module 200; the optical module 200 converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber 101, and the second optical signal is transmitted to the remote information processing device 1000 through the optical fiber 101. For example, a first optical signal from the remote information processing device 1000 is propagated through the optical fiber 101; the first optical signal from the optical fiber 101 is transmitted into the optical module 200; the optical module 200 converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the host computer 100; the host computer generates a fourth electrical signal based on the first electrical signal, and transmits the fourth electrical signal to the local information processing device 2000. It is noted that the optical module is a tool for achieving the conversion between optical and electrical signals, and during the conversion between optical and electrical signals as described above, the information is not changed, but methods for encoding and decoding the information may be changed.

The host computer 100 includes not only an optical network unit but also an optical line terminal (OLT), an optical network terminal (ONT), or a data center server or the like.

FIG. 2 is a partial structural diagram of a host computer according to some embodiments. In order to illustrate a connection relationship between the optical module 200 and the host computer 100 clearly, FIG. 2 only shows the structure of the host computer 100 related to the optical module 200. As shown in FIG. 2, the host computer 100 further includes a PCB circuit board 105 disposed within the housing, a cage 106 disposed on a surface of the PCB circuit board 105, a radiator 107 disposed on the cage 106, and an electrical connector disposed inside the cage 106. The electrical connector is configured to couple with the electrical port of the optical module 200. The radiator 107 has a raised structure, such as a fin, that increases a heat dissipation area.

The optical module 200 is inserted into the cage 106 of the host computer 100 and then is secured by the cage 106. Thus, heat generated by the optical module 200 is conducted to the cage 106, and then dissipated via the radiator 107. After the optical module 200 is inserted into the cage 106, an electrical port of the optical module 200 is connected to the electrical connector inside the cage 106 such that a bidirectional electrical signal connection is established between the optical module 200 and the host computer 100. In addition, the optical port of the optical module 200 is connected to the external optical fiber 101, such that the optical module 200 establishes a bidirectional optical signal connection with the external optical fiber 101.

FIG. 3 is a structural diagram of an optical module according to some embodiments of this disclosure, and FIG. 4 is an exploded diagram of an optical module according to some embodiments. As shown in FIG. 3 and FIG. 4, the optical module 200 includes a shell, and a circuit board 300, an optical component and an optical fiber adapter 700 that are disposed within the shell. The optical fiber adapter 700 may be connected to the optical component through an optical fiber ribbon.

The shell may include an upper shell part 201 and a lower shell part 202. The upper shell part 201 is covered on the lower shell part 202 to form the aforementioned shell having two openings 204 and 205. An outer contour of the shell is generally in a cuboid shape.

In some embodiments, the lower shell part 202 includes a bottom plate 2021 and two lower side plates 2022 located at opposite sides of the bottom plate 2021 and disposed perpendicular to the bottom plate 2021, and the upper shell part 201 includes an upper cover plate 2011 which is covered on the two lower side plates 2022 of the low shell part 202 so as to form the above-mentioned shell.

In some embodiments, the lower shell part 202 includes a bottom plate 2021 and two lower side plates 2022 located on opposite sides of the bottom plate 2021 and disposed perpendicular to the bottom plate 2021; the upper shell part 201 includes a upper cover plate 2011 and two upper side plates located on opposite sides of the upper cover plate 2011 and disposed perpendicular to the upper cover plate 2011, and the two upper side plates are combined with the two lower side plates 2022 such that the upper shell part 201 is covered on the lower shell part 202.

A direction along a connecting line between the two openings 204 and 205 may be consistent with a length direction of the optical module 200 or inconsistent with the length direction of the optical module 200. For example, the opening 204 is located at an end of the optical module 200 (right end in FIG. 3), and the opening 205 is also located at an end of the optical module 200 (left end in FIG. 3). Alternatively, the opening 204 is located at an end of the optical module 200, while the opening 205 is located at a side of the optical module 200. The opening 204 is an electrical port, and a golden finger 301 of the circuit board 300 extends out of the electrical port and is inserted into the electrical connector of the host computer. The opening 205 is an optical port configured to be coupled by the external optical fiber 101 such that the external optical fiber 101 is connected with the optical component of the optical module 200.

The assembling way in which the upper shell part 201 is combined with the lower shell part 202 facilitates mounting the circuit board 300, the optical component, the optical fiber adapter 700 or the like into the above-mentioned shell, such that these components are encapsulated and protected by the upper shell part 201 and the lower shell part 202. In addition, when assembling the circuit board 300, the optical component, the optical fiber adapter 700 or the like, it is easier to deploy positioning elements, heat dissipation elements, and electromagnetic shielding elements of these components with the assembling way in which the upper shell part 201 is combined with the lower shell part 202, which facilitates automate production implementation.

In some embodiments, the upper shell part 201 and the lower shell part 202 are made of metal material(s), which facilitates to achieve electromagnetic shielding and heat dissipation.

In some embodiments, the optical module 200 further includes an unlocking component 600 located outside the shell thereof. The unlocking component 600 is configured to achieve a fixed connection between the optical module 200 and the host computer 100 or to release the fixed connection between the optical module 200 and the host computer 100.

For example, the unlocking component 600 is located outside the two lower side plates 2022 of the lower shell part 202, and includes a snapping part (or an engaging part) that matches with the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the snapping part of the unlocking component 600 secures the optical module 200 within the cage 106. As the unlocking component 600 is pulled, the snapping part of the unlocking component 600 moves accordingly, and thus the connection relationship between the snapping part and the host computer is changed, thereby releasing the fixed connection between the optical module 200 and the host computer, such that the optical module 200 can be drawn out of the cage 106.

The circuit board 300 includes circuit wiring, electronic elements, chips, and so on. The electronic elements and chips are connected together via the circuit wiring according to a circuit design so as to achieve various functions such as power supply, electrical signal transmission, and grounding. For example, the electronic element may include a capacitor, a resistor, a transistor, and a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET). For example, the chip may include a microcontroller unit (MCU), a laser driver chip, a transimpedance amplifier (TIA), a limiting amplifier (LA), a Clock and Data Recovery (CDR) chip, a power management chip, and a digital signal processing (DSP) chip.

The circuit board 300 is generally a rigid circuit board. Also, the rigid circuit board may achieve a carrying function due to its relatively hard material. For example, the rigid circuit board may steadily carry the above-mentioned electronic elements and chips thereon. Furthermore, the rigid circuit board may be easily inserted into the electrical connector inside the cage 106 of the host computer 100.

The circuit board 300 further includes a golden finger 301 formed on a surface of an end thereof, which is composed of multiple independent pins. The circuit board 300 is inserted into the cage 106 and is conductively connected to the electrical connector inside the cage 106 via the golden finger 301. The golden finger 301 may be disposed only on the surface of one side of the circuit board 300 (e.g., an upper surface shown in FIG. 4), or on surfaces of upper and lower sides of the circuit board 300 to provide a larger number of pins, so as to adapt to occasions where a large number of pins are required. The golden finger 301 is configured to establish an electrical connection with the host computer to achieve power supply, grounding, Inter-Integrated Circuit (I2C) signal transmission, data signal transmission or the like. Of course, it is possible to use a flexible circuit board in some optical modules. The flexible circuit board is generally used in cooperation with the rigid circuit board to serve as a supplement to the rigid circuit board.

The optical component is directly disposed on the circuit board 300, and is located at a side of the circuit board 300 away from the golden finger 301.

In some embodiments, the optical component includes at least one of an optical emission component and an optical reception component, and at least one of the optical emission component and the optical reception component can be directly disposed on the circuit board 300. For example, at least one of the optical emission component and the optical reception component can be disposed on the surface of the circuit board 300 or on the side of the circuit board 300.

In some embodiments, the optical component is physically separated from the circuit board 300 and then electrically connected to the circuit board 300 through a corresponding flexible circuit board or electrical connector.

FIG. 5 is a partial structural diagram of an optical module provided according to some embodiments of the present disclosure, and FIG. 6 is a partial exploded diagram of an optical module provided according to some embodiments of the present disclosure. As shown in FIG. 5 and FIG. 6, the optical component includes a first optical component 400 and a second optical component 500. The first optical component 400 and the second optical component 500 may have emitting and receiving functions to realize two groups of optical emission and two groups of optical reception. However, the present disclosure is not limited to this. In some embodiments, the first optical component 400 and the second optical component 500 have one of the optical emission function and optical reception function.

In some embodiments, both the first optical component 400 and the second optical component 500 have both optical emission and optical reception functions, in this case, a light beam emitted by the first optical component 400 is transmitted to the external optical fiber 101 via the first optical fiber ribbon 410 and the optical fiber adapter 700 to achieve the emission of one group of lights; a light beam emitted by the second optical component 500 is transmitted to the external optical fiber 101 via the second optical fiber ribbon 510 and the optical fiber adapter 700 to achieve the emission of another group of lights; a received light beam transmitted by the external optical fiber 101 is transmitted to the first optical component 400 via the optical fiber adapter 700 and the first optical fiber ribbon 410 to achieve reception of one group of lights; a received light beam transmitted by the external optical fiber 101 is transmitted to the second optical component 500 via the optical fiber adapter 700 and the second optical fiber ribbon 510 to achieve reception of another group of lights, thereby achieving emission of two groups of light and reception of two groups of light of the optical module 200.

In some embodiments, an optical fiber plug is disposed at one end of the external optical fiber 101 that is inserted into the optical fiber adapter 700, and the optical fiber plug is inserted into the optical fiber adapter 700 when in use, such that an optical signal transmitted by the optical fiber ribbon is coupled to the external optical fiber through the optical fiber adapter 700, and a received optical signal transmitted by the external optical fiber is transmitted to the first optical component 400 and the second optical component 500 through the optical fiber adapter 700.

In some embodiments, not only the external optical fiber 101 but also an active optical cable (AOC) may be inserted into the optical port of the optical module 200. The AOC, as the main transmission medium for high-performance computing and data centers in the big data era, has such advantages as high bandwidth, anti-electromagnetic interference, long transmission distance, low power consumption, small cable size, easy use and compliance with dense wiring in computer rooms. When an optical cable is inserted into the optical port of the optical module 200, the optical cable and the optical module 200 constitute an AOC optical module.

In order that the external optical fiber 101 or the AOC optical cable can be inserted into the optical port of the optical module 200, the optical module 200 needs to have two optical port structures, respectively. Therefore, the production of the optical module 200 requires two production lines, and the two production lines require two sets of molds, resulting in high production costs of the optical module and low switching efficiency of the two kinds of optical modules.

In order to facilitate switching the optical port of the optical module such that the external optical fiber 101 or the AOC optical cable may be inserted into the optical port, the optical module provided according to the embodiments of the present disclosure can function as an optical transceiver module as well as an AOC optical module. It is only necessary to generate an optical transceiver module TRX, and when needed, the non-AOC optical module may be converted into an AOC optical module by fixing the optical cable plug with a set of anti-disassembly structures, thereby realizing mutual switching between the non-AOC optical module and the AOC optical module.

FIG. 7 is a diagram of an optical cable plug and an optical fiber adapter of an optical module according to some embodiments of the present disclosure in a disassembled state. As shown in FIG. 7, the optical fiber adapter 700 includes a claw member 710 and an optical fiber plug 720. The claw member 710 is formed therein with a through hole. The optical fiber plug 720 is inserted into one end of the through hole. The optical fiber plug 720 is connected to the first optical component 400 and the second optical component 500 through an optical fiber ribbon. The external optical fiber 101 is inserted into the other end of the through hole. The external optical fiber 101 is coupled and connected to the optical fiber plug 720 to achieve coupling between the optical fiber adapter 700 and the external optical fiber 101.

When the external optical fiber 101 is disassembled from the optical fiber adapter 700, an active optical cable 1100 may be inserted into the other end of the through hole via an optical cable plug 900. The active optical cable 1100 is coupled to the optical fiber plug 720 through the claw member 710 to achieve coupling between the active optical cable 1100 and the optical fiber adapter 700, and thus the non-AOC optical module is converted into an AOC optical module.

FIG. 8 is a structural diagram of an optical cable plug of an optical module according to some embodiments of the present disclosure, FIG. 9 is a structural diagram of a claw member of an optical module according to some embodiments of the present disclosure, and FIG. 10 is a structural diagram of a claw member of an optical module according to some embodiments of the present disclosure, which is shown from another perspective. As shown in FIG. 8, FIG. 9 and FIG. 10, the optical cable plug 900 includes a base 900a and a sleeve 905, one end of the base 900a is inserted into the optical fiber adapter 700, the sleeve 905 is sleeved on the base 900a and is slidably connected to the base 900a, and by moving the sleeve 905, the optical cable plug 900 and the optical fiber adapter 700 can be locked, or the optical cable plug 900 and the optical fiber adapter 700 can be disassembled. For example, the base 900a includes a plug-in portion 901 and a connecting portion 906, opposite ends of the connecting portion 906 are fixedly connected to the plug-in portion 901 and the active optical cable 1100, respectively, and the plug-in portion 901 can be inserted into the optical port of the optical module so as to convert the optical module into an AOC optical module.

The sleeve 905 is sleeved on the connecting portion 906, and the sleeve 905 is slidable left and right on the connecting portion 906. When the plug-in portion 901 is inserted to the right into the optical fiber adapter 700, the sleeve 905 is located on the left side of the connecting portion 906 to enable the plug-in portion 901 to be engaged with the optical fiber adapter 700. Then the sleeve 905 is moved to the right to lock the optical cable plug 900 and the optical fiber adapter 700 through the sleeve 905 to prevent the optical cable plug 900 from being detached.

In some embodiments, when an operator unplugs the optical cable 1100, the operator presses the sleeve 905 and moves it leftward, and then unplugs the plug-in portion 901 from the optical fiber adapter 700 to disconnect the optical cable plug 900 from the optical fiber adapter 700.

In some embodiments, a sliding arrow may be provided on a top surface of the sleeve 905, and the operator can identify a forward direction of the optical cable plug 900 according to the sliding arrow. When the optical cable plug 900 is inserted into the optical fiber adapter 700 in the forward direction, the sliding arrow on the sleeve 905 faces the upper shell part 201, thereby preventing the optical cable plug 900 from being inserted into the optical fiber adapter 700 in the reverse direction, ensuring the optical coupling effect between the optical cable plug 900 and the optical fiber adapter 700.

In some embodiments, a protrusion 902 is formed on the top surface of the plug-in portion 901, and the protrusion 902 extends from the right side surface of the plug-in portion 901 to the right side surface of the connecting portion 906. The protrusion 902 is arranged along the left-right direction, and there are gaps between two opposite side surfaces of the protrusion 902 and two opposite side surfaces of the plug-in portion 901, that is, the protrusion 902 is not located on either side edge of the plug-in portion 901, so as to ensure the installation stability of the optical fiber plug 900.

First engaging grooves 904 are formed on opposite side surfaces (the two side surfaces connected to the top surface) of the plug-in portion 901. The first engaging groove 904 extends from the right side surface of the plug-in portion 901 to the right side surface of the connecting portion 906. The first engaging groove 904 is recessed relative to the side surface of the plug-in portion 901, and the first engaging groove 904 has an opening on the right side thereof to facilitate the insertion of the engaging part of the optical fiber adapter 700 into the first engaging groove 904, thereby realizing the coupling connection between the optical cable plug 900 and the optical fiber adapter 700.

In some embodiments, second engaging grooves 908 are provided on opposite side surfaces of the connecting portion 906, and the second engaging grooves 908 are located on the right side of the connecting portion 906. The second engaging groove 908 may be communicated to the first engaging groove 904. When the sleeve 905 is located on the left side of the connecting portion 906, the second engaging groove 908 is exposed, and when the sleeve 905 is slid to the right side of the connecting portion 906, the second engaging groove 908 is located inside the sleeve 905. When the plug-in portion 901 is inserted into the optical fiber adapter 700, the sleeve 905 is slid to the left side, and the engaging parts of the optical fiber adapter 700 can be inserted into the second engaging grooves 908 via the first engaging grooves 904; then the sleeve 905 is slid to the right, such that the sleeve 905 clamps the engaging parts of the optical fiber adapter 700, so as to achieve the locking and fixing of the optical cable plug 900 and the optical fiber adapter 700.

In some embodiments, the second engaging groove 908 and the first engaging groove 904 may not be communicated with each other. When the plug-in portion 901 is inserted into the optical fiber adapter 700, the sleeve 905 is slid to the left, and left ends of the engaging parts of the optical fiber adapter 700 are engaged into the second engaging grooves 908, and middle portions of the engaging parts are engaged into the first engaging grooves 904, so as to clamp the optical cable plug 900 and the optical fiber adapter 700 through the engaging parts.

Referring to FIG. 9, the claw member 710 is formed therein with a through hole 7103, and slots are formed on two opposite sides of the claw member 710, one end of each slot is provided with an opening, and a first engaging part 7101 is provided in the slot. One end of the first engaging part 7101 is fixedly connected to the claw member 710, such that the first engaging part 7101 can be rotated (or turned) at a preset angle in the slot, so that the first engaging part 7101 can be pushed outward or clamped inward. Exemplarily, the first engaging part 7101 may be an elastic engaging part or be a non-elastic engaging part, which is not limited in the present disclosure.

An inner wall of the top portion of the claw member 710 is formed thereon with a guide groove 7102. The guide groove 7102 extends from the left side to the right side of the claw member 710. The guide groove 7102 is configured to guide the optical cable plug 900 to be inserted into the through hole 7103, that is, when the plug-in portion 901 is inserted into the through hole 7103 of the claw member 710, the protrusion 902 on the plug-in portion 901 is inserted into the claw member 710 along the guide groove 7102, and the optical cable plug 900 is fixedly connected through the first engaging parts 7101 on the claw member 710, so as to realize the fixed connection between the optical cable plug 900 and the claw member 710.

In some embodiments, when the plug-in portion 901 is inserted into the through hole 7103, the first engaging part 7101 is engaged into the first engaging groove 904 and the second engaging groove 908, and the optical cable plug 900 inserted into the claw member 710 is fixedly connected through the first engaging parts 7101; then, the sleeve 905 may be slid to the right, and the first engaging parts 7101 are clamped by the sleeve 905, so as to fixedly connect the optical cable plug 900 and the claw member 710 through the first engaging parts 7101.

When pulling the optical cable plug 900 from the optical fiber adapter 700, the operator may slide the sleeve 905 to the left, and then pry or turn the first engaging part 7101 outward to move the optical cable plug 900 to the left, so as to separate the optical cable plug 900 from the optical fiber adapter 700.

In some embodiments, considering that the claw member 710 is an elastic member, if the operator makes an error and inserts the optical cable plug 900 into the claw member 710 in the reverse direction (rotated 360 degrees), the optical cable plug 900 may also expand the claw member 710 and be successfully inserted into the claw member 710, however, under this circumstance, it is impossible for the optical cable plug 900 to couple with the optical fiber plug 720 in the claw member 710, which thereby affects the optical coupling effect.

In order to prevent the optical cable plug 900 from being inserted into the claw member 710 in reverse, the bottom surface of the plug-in portion 901 may be formed thereon with a guide groove, and a guide post may be formed on the inner wall of the bottom portion of the claw member 710. When the optical cable plug 900 is inserted into the claw member 710 in the forward direction, the protrusion 902 on the optical cable plug 900 is inserted into the guide groove 7102 in the claw member 710, and the guide post in the claw member 710 is inserted into the guide groove on the optical cable plug 900; if the optical cable plug 900 is reversed (such as flipped 360 degrees), the protrusion 902 on the optical cable plug 900 would collide with the guide post in the claw member 710, and the guide post blocks the optical cable plug 900 from be moved rightward, so that the optical cable plug 900 cannot be inserted into the plug 710, warning the operator that the insertion operation is reversed, and reminding the operator to correctly insert the optical cable plug 900.

In some embodiments, a limiting surface is formed in the through hole 7103 of the claw member 710, and a diameter of the part of the through hole passing through the limiting surface is smaller than a diameter of the part of the through hole on the left side of the claw member 710. In this way, when the optical cable plug 900 is inserted into the through hole 7103 of the claw member 710, the plug end face of the plug-in part 901 abuts against the limiting surface to limit and fix the optical cable plug 900.

In some embodiments, a socket 903 is formed on the right side surface of the plug-in portion 901, and the socket 903 extends from the right side surface of the plug-in portion 901 toward the left side. When the optical cable plug 900 is inserted into the optical fiber adapter 700, the pin in the optical fiber adapter 700 is inserted into the socket 903 to position the optical cable plug 900 and the optical fiber adapter 700.

Referring to FIG. 7, to facilitate the coupling connection of the optical cable plug 900 with the optical fiber plug 720 when the optical fiber plug 720 is inserted into the claw member 710, the optical fiber adapter 700 further includes a fixing member 730 and a pin 740. One end of the fixing member 730 is in contact with an end surface of the optical fiber plug 720, and the other end of the fixing member 730 is fixedly engaged with the claw member 710. In this way, the optical fiber plug 720 is fixed in the claw member 710 by the fixing member 730.

As shown in FIG. 10, one end of the claw member 710 facing away from the optical cable plug 900 is formed with a second engaging part 7105, and one end of the second engaging part 7105 is fixedly connected to the claw member 710. Two second engaging parts 7105 are formed on the claw member 710, and the two second engaging parts 7105 are respectively fixedly connected to a top portion and a bottom portion of the claw member 710, that is, the two second engaging parts 7105 are arranged in the up-down direction. Exemplarily, the second engaging part 7105 may be an elastic engaging part or have other forms, which is not limited in the present disclosure.

The second engaging part 7105 can be rotated or turned within a preset angle range, so that the second engaging part 7105 can be clamped inward to fix the optical fiber plug 720, and can also be bent outward to remove the optical fiber plug 720.

In some embodiments, the end of the claw member 710 facing away from the optical cable plug 900 has a first side surface 7104, and the through hole 7103 passes through the first side surface 7104. In this way, the optical fiber plug 720 can be inserted into the claw member 710 through the through hole 7103, and the optical fiber plug 720 can be limited by the first side surface 7104.

In some embodiments, the optical fiber plug 720 includes a core and a fixing part, wherein an outer wall of the fixing part protrudes relative to an outer wall of the core, that is, a width of the fixing part in the up-down direction is greater than a width of the core in the up-down direction, and a length of the fixing part in the front-to-back direction is greater than a length of the core in the front-to-back direction.

When the optical fiber plug 720 is inserted into the through hole 7103 of the claw member 710, the core extends into the through hole 7103, and a second side surface where the core is connected to the fixing part abuts against the first side surface 7104, so as to limit the optical fiber plug 720 through the first side surface 7104, such that the fixing part is located outside the through hole 7103.

In some embodiments, the second engaging part 7105 of the claw member 710 protrudes relative to the first side surface 7104, and when the core of the optical fiber plug 720 is inserted into the through hole 7103 of the claw member 710, the fixing part of the optical fiber plug 720 is located in a gap between the second engaging part 7105 and the first side surface 7104.

The fixing part of the optical fiber plug 720 also includes a third side surface facing away from the core, and the third side surface contacts one end surface of the fixing member 730. When the core of the optical fiber plug 720 is inserted into the through hole 7103 of the claw member 710, the second side surface of the optical fiber plug 720 is abutted against the first side surface 7104 of the claw member 710, and the fixing member 730 is abutted on the third side surface of the optical fiber plug 720, and the second engaging part 7105 abuts against the end surface of the fixing member 730 to apply a force to the fixing member 730 and the optical fiber plug 720, such that the optical fiber plug 720 and the fixing member 730 are held in the claw member 710.

In some embodiments, an optical fiber socket is formed on the third side surface of the optical fiber plug 720, and a plurality of optical fiber holes are formed on the side surface where the core is inserted into the through hole 7103, and the plurality of optical fiber holes are communicated to the optical fiber socket, such that the optical fiber ribbon is inserted into the optical fiber plug 720 through the optical fiber socket, and each optical fiber of the optical fiber ribbon is placed in one optical fiber hole.

When the optical fiber is placed in the optical fiber hole, a light exiting surface of the optical fiber is located outside the optical fiber plug 720. Thus, when the optical fiber plug 720 and the optical cable plug 900 are connected in the claw member 710, the optical signal transmitted by the optical fiber is directly coupled to the optical cable plug 900.

In some embodiments, the optical fiber plug 720 may be an MT male connector, and the optical cable plug 900 may correspondingly be a MT female connector. After the pin 740 is fixedly connected to the optical fiber plug 720, the pin 740 protrudes from the optical fiber plug 720 toward the optical cable plug 900. In this way, when the optical cable plug 900 is inserted into the claw member 710, the protruding pin 740 is inserted into the socket 903 on the end face of the optical cable plug 900, so as to realize the positioning and connection between the optical fiber plug 720 and the optical cable plug 900 through the pin 740.

As shown in FIG. 11 and FIG. 12, when assembling the optical fiber adapter 700 and the optical cable plug 900, firstly, one side surface of the fixing member 730 is placed against the third side surface of the optical fiber plug 720, and then the pin 740 is inserted into a pin hole of the optical fiber plug 720 through the through hole in the fixing member 730, and the pin 740 is fixedly connected to the optical fiber plug 720 through the fixing member 730; then, the assembled optical fiber plug 720, the fixing member 730 and the pin 740 are inserted into the through hole 7103 of the claw member 710, such that the second side surface of the optical fiber plug 720 is in contact with the first side surface 7104 of the claw member 710, and the second engaging part 7105 abuts against the fixing member 730, thereby fixing the optical fiber plug 720 and the fixing member 730 in the claw member 710.

Then, the plug-in portion 901 of the optical cable plug 900 is inserted into the other end of the claw member 710, and the left end of the pin 740 is inserted into the socket 903 of the optical cable plug 900 until the right side surface of the plug-in portion 901 abuts against the limiting surface in the through hole 7103; and then the first engaging parts 7101 are engaged into the first engaging groove 904 and the second engaging groove 908, and the optical cable plug 900 inserted into the claw member 710 is clamped by the first engaging parts 7101; and then the sleeve 905 is slid to the right to clamp the first engaging parts 7101. In this way, the optical cable plug 900 is clamped in the claw member 710, and the coupling connection between the optical cable plug 900 and the optical fiber adapter 700 is realized.

In some embodiments, when locking the plug-in portion 901 and the claw member 710 by sliding the sleeve 905, the operator may accidentally touch the sleeve 905, causing the sleeve 905 to slide to the left, so that the optical cable plug 900 and the claw member 710 are easily to be separated, resulting in abnormal detachment of the optical cable plug 900.

For example, the locking boss 914 may be formed in the first protective cover 910 or the second protective cover 920, or both the first protective cover 910 and the second protective cover 920 may be formed with the locking boss 914. With the sleeve 905 being held by the locking boss 914, the anti-disassembly function of the optical cable plug 900 is achieved.

In some embodiments, the locking boss 914 is formed on the inner side of the second cover plate 912, the locking boss 914 is located between the first side plate 913 and the second side plate 917, and the locking boss 914 is arranged along a width direction of the second cover plate 912; a limiting groove 907 is formed on the connecting portion 906 of the optical cable plug 900, and the limiting groove 907 is close to the left side of the connecting portion 906. When the sleeve 905 is located on the left side of the connecting portion 906, the sleeve 905 hides the limiting groove 907.

After the plug-in portion 901 of the optical cable plug 900 is inserted into the claw member 710, the sleeve 905 is moved to the right to lock the optical cable plug 900 and the claw member 710, and then the first protective cover 910 and the second protective cover 920 are covered on the optical cable plug 900, such that the locking boss 914 is embedded in the limiting groove 907. The locking boss 914 can prevent the sleeve 905 from sliding left and right on the connecting portion 906, thereby realizing the anti-disassembly function of the optical cable plug 900.

In some embodiments, two locking bosses 914, namely a first locking boss and a second locking boss, may be formed on the inner side of the second cover plate 912. One locking boss 914, such as the first locking boss, extends from an inner side of the first side plate 913 toward the second side plate 917, and the other locking boss 914, such as the second locking boss, extends from an inner side of the second side plate 917 toward the first side plate 913, and there is a gap between the two locking bosses 914.

The connecting portion 906 may be formed thereon with two limiting grooves, and one limiting groove 907 is arranged corresponding to one locking boss 914. The two locking bosses 914 are respectively embedded in the limiting grooves 907 on the optical cable plug 900 to lock and limit the sleeve 905 through the locking bosses 914.

The connecting portion 906 may also be formed thereon with one limiting groove 907, and the limiting groove 907 is arranged around the side of the connecting portion 906, that is, the limiting groove 907 is a limiting groove.

In this way, the first side plate 913, the first plate 9141, the connecting plate 9142 and the second plate 9143 form a U-shaped structure.

In some embodiments, when the locking boss 914 is a U-shaped rib, for example, the first locking boss and the second locking boss are U-shaped ribs, and the locking boss 914 support the first side plate 913 and the second side plate 917, such that the outer side of the second cover plate 912 is not easy to shrink, and the appearance is smooth and beautiful. The U-shaped rib is high in strength, and can effectively realize the anti-disassembly function of the optical cable plug 900.

FIG. 19 is a fifth structural diagram of a first protective cover of an optical module provided according to some embodiments of the present disclosure. As shown in FIG. 19, the locking boss 914 on the second cover plate 912 can also be designed as two ribs, that is, one end of the U-shaped rib has an opening, to form two parallel ribs, the two ribs are embedded in the limiting groove 907, and one rib is abutted against the sleeve 905, so that the sleeve 905 is locked and limited by the two ribs.

In some embodiments, two locking bosses 914 are formed on the inner side of the second cover plate 912, and each locking boss includes two ribs arranged left to right, that is, the first locking boss includes two ribs, and the second locking boss includes two ribs; and there is a gap between the two ribs. Two ribs are arranged on the inner side of the second cover plate 912, and the first side plate 913 and the second side plate 917 are supported by the ribs, so that the outer side of the second cover plate 912 is not easy to shrink, and the appearance is smooth and beautiful.

FIG. 20 is a sixth structural diagram of the first protective cover of an optical module provided according to some embodiments of the present disclosure. As shown in FIG. 20, the locking boss 914 on the second cover plate 912 may also be a raised platform, and two raised platforms are formed on the inner side of the second cover plate 912, one raised platform extends from the first side plate 913 toward the second side plate 917, and the other extends from the second side plate 917 toward the first side plate 913, and there is a gap between the two raised platforms. In this way, when the first protective cover 910 and the second protective cover 920 are covered on the sleeve 905, the raised platforms are embedded in the limiting groove 907, and one side of each raised platform is in contact with the sleeve 905, and the sleeve 905 is locked and limited by the raised platforms.

In a case that a raised platform with a certain thickness is provided in the second cover plate 912, the outer side of the second cover plate 912 may be easily shrunk due to the large thickness of the raised platform, resulting in a poor appearance.

FIG. 21 is a seventh structural diagram of the first protective cover of an optical module provided according to some embodiments of the present disclosure. As shown in FIG. 21, the locking boss 914 on the second cover plate 912 may also be designed as two ribs, and each of the two ribs extends from the inner side of the first side plate 913 to the inner side of the second side plate 917. The two ribs are arranged along the left-right direction, and there is a gap between the two ribs in the left-right direction. In this way, when the first protective cover 910 and the second protective cover 920 are covered on the sleeve 905, the two ribs are embedded in the limiting groove 907, and the sleeve 905 is locked and limited by the two ribs.

In the case that two ribs are provided on the second cover plate 912, which extend from the first side plate 913 to the second side plate 917, the limiting groove 907 formed on the connecting portion 906 needs to run across a width direction of the connecting portion 906. However, the limiting groove 907 designed in this way may be not suitable for all optical cable plugs 900, and thus the first protective cover 910 and the second protective cover 920 of this structure may not be adapted to all AOC optical cables on the market.

FIG. 22 is an eighth structural diagram of a first protective cover of an optical module provided according to some embodiments of the present disclosure. As shown in FIG. 22, the locking boss 914 on the second cover plate 912 may also be designed as one rib, the rib has a certain wall thickness, and extends from the inner side of the first side plate 913 to the inner side of the second side plate 917; and the limiting groove 907 on the connecting portion 906 is a limiting groove. In this way, when the first protective cover 910 and the second protective cover 920 are covered on the sleeve 905, the wider rib is embedded in the limiting groove, and the sleeve 905 is locked and limited by one wider rib.

In the case that one rib, which runs from the first side plate 913 to the second side plate 917, is provided on the second cover plate 912, since the rib has a relatively thick wall, it may cause the outer side of the second cover plate 912 to shrink, resulting in a poor appearance, and thus it may be unable to adapt to all AOC optical cables on the market.

FIG. 23 is a sectional view of an optical cable plug and a protective cover of an optical module provided according to some embodiments of the present disclosure in an assembled state. As shown in FIG. 23, the optical cable plug 900 is inserted into the optical fiber adapter 700, and the optical cable plug 900 is locked and connected with the claw member 710 of the optical fiber adapter 700 through the sleeve 905, and then the first protective cover 910 and the second protective cover 920 are covered on the optical cable plug 900, and the locking bosses 914 on the first protective cover 910 and the second protective cover 920 are embedded in the limit groove 907 on the optical cable plug 900, the first protective cover 910 and the second protective cover 920 are engaged and connected to each other, the sleeve 905 on the optical cable plug 900 cannot slide on the connecting portion 906 of the optical cable plug 900 because of the locking bosses 914, and the first protective cover 910 and the second protective cover 920 shield the sleeve 905, such that the operator cannot contact the sleeve 905, thereby preventing abnormal disassembly of the optical cable plug 900.

When the operator wants to separate the optical cable plug 900 from the optical fiber adapter 700, the operator first separates the first protective cover 910, the second protective cover 920 and the optical cable plug 900, and then pushes the sleeve 905 to the left to facilitate pulling the first engaging parts 7101 such that the first engaging parts 7101 on the claw member 710 are disengaged from the first engaging groove 904 and the second engaging groove 908 on both sides of the optical cable plug 900, so as to achieve the separation of the optical cable plug 900 from the optical fiber adapter 700, thereby converting the AOC optical module into a non-AOC optical module.

In some embodiments, when inserting the optical cable plug 900 into the claw member 710, a part of the sleeve 905 on the optical cable plug 900 may be inserted into the optical port formed by the upper shell part 201 and the lower shell part 202, such that the optical cable plug 900 is sufficiently inserted, thereby ensuring the installation stability of the optical cable plug 900 and the optical fiber adapter 700.

FIG. 24 is a partial structural diagram of an upper shell part of an optical module provided according to some embodiments of the present disclosure, FIG. 25 is a partial assembly diagram of an optical cable plug, an upper shell part and an optical fiber adapter of an optical module provided according to some embodiments of the present disclosure, and FIG. 26 is a sectional view of an optical cable plug, an upper shell part and an optical fiber adapter of an optical module provided according to some embodiments of the present disclosure in an assembled state. As shown in FIG. 24, FIG. 25 and FIG. 26, the upper side plate 2012 of the upper shell part 201 is formed thereon with an arc-shaped plate 2013, which extends from a left side surface of the upper shell part 201 toward a right side of the upper shell part 201; the lower side plate 2022 of the lower shell part 202 is also formed with an arc-shaped plate, which extends from a left side surface of the lower shell part 202 toward a right side of the lower shell part 202. When the optical cable plug 900 is inserted into the optical fiber adapter 700, the arc-shaped plate 2013 contacts the outer arc surface of the sleeve 905, such that the sleeve 905 of the optical cable plug 900 can be inserted into the optical port of the optical module, and the optical cable plug 900 is sufficiently inserted, thereby facilitating the coupling connection between the optical cable plug 900 and the optical fiber plug 720.

In some embodiments, the upper cover plate 2011 of the upper shell part 201 is formed thereon with a baffle 2014, which is arranged in the left-right direction. There is a gap between a left side surface of the baffle 2014 and a left side surface of the upper shell part 201. When inserting the optical cable plug 900 into the optical fiber adapter 700, a bottom surface of the sleeve 905 of the optical cable plug 900 abuts against the baffle 2014, so as to limit the optical cable plug 900 with the baffle 2014 to ensure that the optical cable plug 900 and the optical fiber plug 720 are connected in the claw member 710.

In some embodiments, the upper shell part 201 may be formed thereon with a limiting groove, the limiting groove may extend from the left side surface of the upper shell part 201 toward the right side of the upper shell part, and the limiting groove may be an arc-shaped groove; a convex shell is formed on a right side surface of the first protective cover 910 or the second protective cover, and the convex shell protrudes relative to the right side surface of the protective cover. When the first protective cover 910 and the second protective cover 920 are covered on the optical cable plug 900, the convex shell on the protective cover is embedded in the limiting groove of the upper shell part 201, so as to limit the protective cover through the limiting groove on the shell.

FIG. 27 is a partial sectional view of an optical module provided according to some embodiments of the present disclosure. As shown in FIG. 27, the optical cable plug 900 is inserted into the claw member 710, and a portion of the sleeve 905 is inserted into the optical port formed by the upper shell part 201 and the lower shell part 202; the outer arc surface of the sleeve 905 contacts the arc-shaped plate 2013 on the upper shell part 201 and the arc-shaped plate on the lower shell part 202; the baffle 2014 on the upper shell part 201 limits the sleeve 905, such that the right sides of the first protective cover 910 and the second protective cover 920 which wrap the optical cable plug 900 abut against the left sides of the upper shell part 201 and the lower shell part 202, the optical cable plug 900 is installed in place, and the non-AOC optical module is converted into an AOC optical module.

In some embodiments, a non-AOC optical module is converted into an AOC optical module by connecting the optical cable plug 900 with the optical fiber adapter 700. For optical module manufacturers, they only need to schedule the production of non-AOC optical modules, and when AOC optical modules are needed, they only need to add related cable components, the production conversion is very convenient, which effectively improves the production efficiency of optical modules. Since there is no need to provide new AOC molds, the cost of each set of molds may be reduced by tens of thousands to hundreds of thousands, which effectively reduces the production costs, effectively reduces the inventory cost and improvs turnover efficiency.

For clients, with the optical module which may be changed from an non-AOC optical module to an AOC optical module, procurement costs and installation fees are reduced, which is similar to the separation of the charging plug and the charging cable, the non-AOC optical module is equivalent to the charging head, and customers can randomly switch between optical fiber cables of different lengths such as 1 m, 2 m, 3 m, 5 m, and 10 m according to different usage scenarios, and the switching is very convenient and easy.

FIG. 28A is a structural diagram of another optical cable plug according to some embodiments, and FIG. 28B is a sectional view of another optical cable plug according to some embodiments. As shown in FIG. 28A and FIG. 28B, similar to the above embodiments, in some embodiments, the sleeve 905 of the optical cable plug 900 can move along the base 900a, for example, the sleeve 905 can move along the arrow directions shown in FIG. 28A. In an exemplary embodiment, the sleeve 905 can move within a preset length range of the base 900a.

In some embodiments, the base 900a is formed with a locking portion 811 (e.g., an engaging groove), and the locking portion 811 may lock and connect the optical fiber adapter 700. The locking portion 811 is located below the sleeve 905, and the locking portion 811 can cooperate with the sleeve 905 to lock the base 900a and the optical fiber adapter 700. For instance, both sides of the base 900a may be disposed with the locking portions 811.

In some embodiments, a limiting boss 812 is formed on a side of one end of the base 900a, and a limiting groove 907 is formed between a side of the limiting boss 812 and one end of the sleeve 905. When the sleeve 905 moves along the base 900a, one end of the sleeve 905 approaches the limiting boss 812, and the limiting groove 907 between the end of the sleeve 905 and the limiting boss 812 is shortened.

FIG. 28C is a first sectional view of another optical module according to some embodiments. FIG. 28C shows a locking state of an optical cable plug and an optical fiber adapter. As shown in FIG. 28C, in some embodiments, the claw member 710 of the optical fiber adapter 700 is configured to lock and connect the optical cable plug 900. In an exemplary embodiment, when the optical cable plug 900 is connected to the optical fiber adapter 700, an inner side of the claw member 710 is assembled and connected with the locking portion 811, and an outer side of the claw member 710 is assembled and connected with the sleeve 905. The sleeve 905, the claw member 710 and the locking portion 811 are assembled and connected to achieve locking and connection between the claw member 710 and the base 900a, thereby achieving locking connection between the optical cable plug 900 and the optical fiber adapter 700.

In some embodiments, when the sleeve 905 is dragged to move toward the limiting boss 812, one end of the sleeve 905 is close to the side of the limiting boss 812, the sleeve 905 is disengaged from the claw member 710, the claw member 710 is then disengaged from the locking portion 811, and then the optical cable plug 900 and the optical fiber adapter 700 are unlocked, thereby enabling the optical fiber connection 900 to be disengaged from the optical fiber adapter 700.

In some embodiments, the optical cable plug 900 may include an elastic member 830, the clastic member 830 may connect the sleeve 905 and the base 900a. The elastic member 830 may be a spring or a tension spring. For example, when unlocking the optical cable plug 900 and the optical fiber adapter 700, an external force overcomes the deformation force of the elastic member 830 to move the sleeve 905, and when the external force becomes smaller or disappears, the sleeve 905 returns to its original position under the deformation force of the elastic member 830. In this way, the elastic member 830 may also help to strengthen the locking of the optical cable plug 900 and the optical fiber adapter 700 to a certain extent, such that an external force, that is less than a certain strength, is not easy to unlock the sleeve 905 and the claw member 710.

In some embodiments, in order to make it more difficult for the optical cable plug 900 and the optical fiber adapter 700 to be unlocked, the optical module 200 may include an anti-unlocking component 930. The anti-unlocking component 930 is disposed on the optical cable plug 900 and is configured to prevent the sleeve 905 from moving.

FIG. 29A is a diagram showing a connection state of another optical cable plug and an anti-unlocking component according to some embodiments, and FIG. 29B is a sectional view of another optical cable plug and an anti-unlocking component according to some embodiments. As shown in FIG. 29A and FIG. 29B, different from the above embodiments described in conjunction with FIG. 13 to FIG. 27, in some examples, the anti-unlocking component 930 on the optical cable plug 900 is located at one end of the base 930a, and the anti-unlocking component 930 is configured to prevent the sleeve 905 from moving, so as to prevent the optical cable plug 900 from unlocking from the optical fiber adapter 700, and realize the fixed connection between the optical cable plug 900 and the optical fiber adapter 700.

In some embodiments, when the anti-unlocking component 930 is assembled to the optical cable plug 900, the optical cable plug 900 and the optical fiber adapter 700 cannot be unlocked; when the anti-unlocking component 930 is removed from the optical cable plug 900, the optical cable plug 900 and the optical fiber adapter 700 can be unlocked. In this way, with the arrangement of the anti-unlocking component 930, switching of two modes of pluggable connection and fixed connection between the optical cable plug 900 and the optical fiber adapter 700 is achieved. As an example, the anti-unlocking component 930 is detachably connected to the optical cable plug 900, the sleeve 905 is blocked by the anti-unlocking component 930, which is easier to repair than a case in which the sleeve 905 and the base 930a are fixedly connected by glue.

In some embodiments, the anti-unlocking component 930 may include a locking mechanism 931. The locking mechanism 931 is embedded in the limiting groove 907 to occupy the limiting groove 907, such that the sleeve 905 cannot move toward the limiting boss 812, or a moving distance of the sleeve 905 toward the limiting boss 812 is reduced, and the sleeve 905 and the claw member 710 cannot be separated. The locking mechanism 931 may be a locking protrusion or a locking rib, etc.

In some embodiments, the anti-unlocking component 930 may include a connecting mechanism 932. The connecting mechanism 932 is connected to the base 930a and is arranged outside the locking mechanism 931 to facilitate the connection between the anti-unlocking component 930 and the optical cable plug 900 and to facilitate to embed the locking mechanism 931 in the limiting groove 907. Exemplarily, the connecting mechanism 932 is sleeved on one end of the base 930a. For example, the connecting mechanism 932 tightly enclasps the limiting boss 812.

FIG. 29C is a second sectional view of another optical module according to some embodiments, and FIG. 29B and FIG. 29C show a use state of an anti-unlocking component. As shown in FIG. 29B and FIG. 29C, in some embodiments, the connecting mechanism 932 is connected to the base 930a, and a free end of the locking mechanism 931 is embedded in the limit groove 907. The locking mechanism 931 occupies a space required for the sleeve 905 to be unlocked, such that the sleeve 905 cannot move toward the limiting boss 812 or its moving distance toward the limiting boss 812 is small, making it impossible for the sleeve 905 to be separated from the claw member 710, and the optical cable plug 900 and the optical fiber adapter 700 remain in a locked state.

In some embodiments, one side of the locking mechanism 931 may contact and connect with the side of the limiting boss 812, and the other side of the locking mechanism 931 may contact and connect with an end surface of the sleeve 905, such that the locking mechanism 931 is placed in the limit groove 907 in an interference fit manner, thereby making the sleeve 905 immovable.

In some embodiments, one side of the locking mechanism 931 may contact and connect with the side of the limiting boss 812, but the other side of the locking mechanism 931 does not contact the end face of the sleeve 905, and a distance between the other side of the locking mechanism 931 and said end face should be less than the minimum unlocking moving distance. One side of the locking mechanism 931 contacts the side of the limiting boss 812 makes it convenient to position and assemble the anti-unlocking component 930. Exemplarily, the distance between the other side of the locking mechanism 931 and the end face of the sleeve 905 is greater than one-fourth of the minimum unlocking moving distance, which is convenient for assembling the locking mechanism 931 in the limit groove 907; the distance between the other side of the locking mechanism 931 and the end face of the sleeve 905 is less than half of the minimum unlocking moving distance, which is convenient for preventing the deformation of the sleeve 905 from causing the optical cable plug 900 and the optical fiber adapter 700 to be unlocked.

In some embodiments, one side of the locking mechanism 931 does not contact the side of the limiting boss 812, while the other side of the locking mechanism 931 can contact the end surface of the sleeve 905. The other side of the locking mechanism 931 contacts the end surface of the sleeve 905 makes it convenient to position and assemble the anti-unlocking component 930. The distance between the one side of the locking mechanism 931 and the side of the limiting boss 812 should be less than the minimum unlocking moving distance. Exemplarily, the distance between one side of the locking mechanism 931 and the side of the limiting boss 812 is greater than one-fourth of the minimum unlocking moving distance, which facilitates the assembly of the locking mechanism 931 in the limit groove 907; the distance between the other side of the locking mechanism 931 and the end surface of the sleeve 905 is less than one-third of the minimum unlocking moving distance, which reduces a risk that the anti-unlocking component 930 moves and causes the optical cable plug 900 and the optical fiber adapter 700 to be unlocked.

In some embodiments, a surface of the connecting mechanism 932 is located at a higher level than a surface of the sleeve 905 to prevent the sleeve 905 from moving toward the limiting boss 812 when being deformed, thereby reducing the risk of unlocking the optical cable plug 900 and the optical fiber adapter 700.

FIG. 29D is a sectional view of an optical cable plug and an optical fiber adapter according to some embodiments. As shown in FIG. 29B and FIG. 29D, in some embodiments, the optical fiber adapter 700 has an assembly plane 702 which is configured to assemble and connect with the shell of the optical module 200. When the optical cable plug 900 is locked and connected to the optical fiber adapter 700, the assembly plane 702 protrudes relative to the surface of the sleeve 905. The surface of the connecting mechanism 932 is lower than the assembly plane 702 or is flush with the assembly plane 702, which is convenient for controlling a length, width and height of an assembly formed by the optical cable plug 900 and the anti-unlocking component 930 after they are assembled and connected, so as to control the length, width and height of the assembly formed by the optical cable plug 900 and the anti-unlocking component 930 after they are assembled and connected within a small range on the basis of ensuring the strength of the anti-unlocking component 930, to adapt to size requirements of an optical module, for example, to make the anti-unlocking component 930 adapt to an optical module which has two optical fiber adapters 700 arranged at the optical port.

One locking mechanism 931a is arranged in the limiting groove 907a, and one locking mechanism 931b is arranged in the limiting groove 907b, so as to realize blocking the movement of the sleeve 905 from multiple directions, and to improve the performance of the anti-unlocking component 930 in blocking the movement of the sleeve 905.

In some embodiments, the connection mechanism 932 includes a first connecting member 932a and a second connecting member 932b, one end of the first connecting member 932a is connected to one end of the second connecting member 932b, and the other end of the first connecting member 932a is connected to the other end of the second connecting member 932b. Exemplarily, both ends of the first connecting member 932a may be detachably connected to both ends of the second connecting member 932b, so as to facilitate the assembling of the anti-unlocking component 930 on the optical cable plug 900, and to make the anti-unlocking component 930 miniaturized as much as possible. For example, an engaging part is provided on one end of the first connecting member 932a, an engaging groove is provided on one end of the second connecting member 932b, an engaging groove is provided on the other end of the first connecting member 932a, and an engaging part is provided on the other end of the second connecting member 932b; or, engaging parts are provided on both ends of the first connecting member 932a, and engaging grooves are provided on both ends of the second connecting member 932b; etc.

In some embodiments, the connecting member (i.e., the first connecting member 932a and the second connecting member 932b) may include a bridge portion 921. The bridge portion 921 is located on one side of the optical cable plug 900; the locking mechanism 931 is disposed on an inner side of the bridge portion 921, and an outer side of the bridge portion 921 protrudes relative to the sleeve 905. The locking mechanism 931 is disposed on an inner side of the bridge portion 921.

In some embodiments, one side of the bridge portion 921 covers on the limiting boss 812, and the other side of the bridge portion 921 contacts and connects an end surface of the sleeve 905.

In some embodiments, the locking mechanism 931 includes a first locking protrusion 911a and a second locking protrusion 912a formed on the inner side of the bridge portion 921. The first locking protrusion 911a and the second locking protrusion 912a are embedded in the limit groove 907. Exemplarily, the first locking protrusion 911a is located at one end of the inner side of the bridge portion 921, and the second locking protrusion 912a is located at the other end of the inner side of the bridge portion 921, and there is a gap between the first locking protrusion 911a and the second locking protrusion 912a. Of course, in some embodiments, the first locking protrusion 911a may be connected to the second locking protrusion 912a to form a locking protrusion that runs through one end of the inner side of the bridge portion 921 to the other end of the inner side of the bridge portion 921.

In some embodiments, a first groove 9111 may be formed on the first locking protrusion 911a. The first groove 9111 may reduce defects generated when molding the first locking protrusion 911a so as to increase the strength of the first locking protrusion 911a. Exemplarily, a depth of the first groove 9111 is less than a thickness of the first locking protrusion 911a.

In some embodiments, the second locking protrusion 912a may be formed thereon with a second groove 9121. The second groove 9121 may reduce defects generated when molding the second groove 9121 so as to increase the strength of the second locking protrusion 912a.

The third blocking surface 9122 is configured to abut against the end surface of the sleeve 905. The third blocking surface 9122 can be flush with the second blocking surface 9211.

In one embodiment, a width of the first locking protrusion 911a is smaller than a width of the bridging portion 921, and a width of the second locking protrusion 912a is smaller than the width of the bridging portion 921, so as to facilitate assembling the first locking protrusion 911a and the second locking protrusion 912a in the limit groove 907, and to block the sleeve 905 via the bridging portion 921.

In some embodiments, the connecting member may include a first connecting portion 922 and a second connecting portion 923. One end of the bridge portion 921 is connected with the first connecting portion 922, and the other end of the bridge portion 921 is connected with the second connecting portion 923. An inner side surface of the first connecting portion 922 and is opposite to an inner side surface of the second connecting portion 923, and the inner side surface of the first connecting portion 922 and the inner side surface of the second connecting portion 923 are configured to assemble and connect with the base 930a. The first connecting portion 922 may be formed thereon with an engaging groove, an engaging part, a positioning hole or a positioning post, etc.; and the second connecting portion 923 may be formed thereon with an engaging groove, an engaging part, a positioning hole or a positioning post, etc.

The handle 610 of the unlocking component 600 can be rotated around the unlocker, to expose the optical port of the optical module. When switching from a non-AOC optical module to an AOC optical module, the external optical fiber 101 at the optical port may be pulled out, and the optical cable plug 900 at one end of the optical cable 1100 is inserted into the claw member 710 of the optical fiber adapter 700; the first protective cover 910 and the second protective cover 920 are placed on the optical cable plug 900 such that the sleeve 905 is locked with the locking bosses in the first protective cover 910 and the second protective cover 920 to prevent abnormal disassembly of the optical cable plug 900 and the optical fiber adapter 700; finally, the handle 610 is turned counterclockwise to its original position, thereby converting the non-AOC optical module into an AOC optical module.

A pair of first protective cover 910 and second protective cover 920 that can be engaged up and down are mounted on the optical cable plug 900, and the sleeve 905 of the optical cable plug is locked through the locking bosses on the protective covers, such that the sleeve 905 cannot slide on the connecting portion 906; and the first engaging part 7101 of the claw member 710 is locked through the sleeve 905, thereby ensuring a stable connection between the optical cable plug 900 and the claw member 710, and preventing the optical cable plug 900 from being abnormally disassembled.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
