1. Technical Field
The present disclosure relates to data transmission systems, particularly to a data transmission system transmitting optical signals and an optical data cable being employed.
2. Description of Related Art
A data cable may be used to connect together two electronic devices for the transmission of data between the two electronic devices. Optical fiber cables transmit optical signals quickly; therefore, the optical fiber cables have become popular for transmitting data between electronic devices. However, when either of the electronic devices is a slave device, such as an USB flash drive, for example, the optical fiber cables cannot transmit data between the aforementioned electronic devices.
Therefore, there is room for improvement in the art.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.
The first electronic device 10 includes a main body 11, a first processor 13 (shown in
The main body 11 defines a first inserting port 111 at a sidewall thereof, for allowing the optical data cable 50 to be inserted in. The first processor 13 includes a first data processing module 131, a first signal emitting module 133, a first signal receiving module 135, and an electrical power emitting module 137. The first signal emitting module 133, the first signal receiving module 135, and the electrical power emitting module 137 are electrically connected to the first data processing module 131, and are electrically connected to the first inserting port 111 via copper wires (not shown), respectively. The power supply 15 is electrically connected to the first data processing module 131, for providing electrical power to the first data processing module 131. In other embodiment, the power supply 15 can be an outer electrical power source. The electrical power emitting module 137 can be directly connected to the power supply 15.
The second electrical device 30 includes a base body 31 and a second processor 33. The base body 31 defines a second inserting port 311, for allowing the optical data cable 50 to be inserted in. The second processor 33 includes a second data processing module 331, a second signal receiving module 333, and a second signal emitting module 335; the second processor 33 is received in the base body 31. The second signal receiving module 333 and the second signal emitting module 335 are electrically connected to the second data processing module 331, and are electrically connected to the second inserting port 311 via copper wires (not shown), respectively.

The first connecting member 51 includes a first housing 511 and a first photoelectric conversion module 513 (shown in
The signal transmitting cable 55 includes at least one optical fiber 551, at least one electrical wire 553, and at least one ground wire 555. The two distal ends of the optical fiber 551 are connected to the first photoelectric conversion module 513 and the second photoelectric conversion module 533, respectively. The two distal ends of the electrical wire 553 and the ground wire 555 extend from the first connecting member 51 to the second connecting member 53, respectively. The end of the electrical wire 553 near to the second connecting member 53 connects with the second photoelectric conversion module 533. When the first connecting member 51 is inserted into the first inserting port 111, the end of the electrical wire 553 near to the first connecting member 51 connects with the electrical power emitting module 137. In the embodiment, there are two optical fibers 551, two electrical wires 553, and two ground wires 555. The optical fibers 551 are active optical fibers. The two electrical wires 553 are for transmitting electrical power of different voltages, to suit the needs of different electronic devices.
In use, the first connecting member 51 is inserted into the first inserting port 111, and the second connecting member 53 is inserted into the second inserting port 311. The electrical power emitting module 137 emits electrical power provided by the power supply 15 to the second connecting member 53 via the first connecting member 51 and the electrical wires 553 to start the second photoelectric conversion module 533. The first signal emitting module 133 emits electrical signals from the first data processing module 131 to the first photoelectric conversion module 513, and the first photoelectric conversion module 513 converts the electrical signals to optical signals. The optical fibers 551 transmits the optical signals to the second photoelectric conversion module 533, and the second photoelectric conversion module 533 converts the optical signals to electrical signals, and the electrical signals are transmitted to the second data processing module 331. Therefore, the data of the first electronic device 10 is transmitted to the second electronic device 30. The data of the second electronic device 30 can be transmitted to the first electronic device 10 using the same way as aforementioned. During the transmission of data, the ground wires 555 ensure safety when transmitting electrical power.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the embodiments or sacrificing all of its material advantages.
