Optical modules are widely used in application scenarios such as data centers, base stations, Local Area Networks (LAN), backbone networks, and/or the like. As accessory products, optical modules may fail during use, causing reduced performance or unplanned downtime at the data center and resulting in significant cost to the user. To address this issue, the present disclosure introduces a transceiver module comprising a first optical module, a second optical module, and an adapter. Should an active optical module fail during operations, the adapter may be configured to detect this failure and redirect traffic from a failing/failed optical module into its paired counterpart for continued performance.
In some embodiments, one optical module is operationally active while the other remains operationally inactive or idle. Both the optical modules are connected to a pair of 1×2 optical switches housed within the adapter, with one optical switch handling data transmission and the other handling data reception. During operation, the active optical module handles incoming and outgoing traffic to and from the source (e.g., server). Should the active optical module fail, the adapter detects this failure and, in response, (i) activates the operationally inactive optical module, and (ii) triggers the source to redirect traffic into the second optical module. The now active optical module takes over and handles incoming and outgoing traffic to and from the server, providing continued performance.
In some embodiments, the adapter 110 may be configured to operate in two configurations, such as a first configuration and a second configuration. In one aspect, the first configuration may be a default configuration of operation, where the first optical module 101 may be operationally active. The second configuration may be a contingent configuration that is implemented when the first optical module 101 operationally fails. When such a failure is detected, the second optical module 103, which is otherwise operationally inactive or idle, may be engaged become operationally active and handle all network traffic that was initially handled by the first optical module 101.
In some embodiments, the transceiver module 100 may be configured to operate in a leaf-spine architecture. A leaf-spine architecture is a data center network topology that may include two switching layers—a spine layer and a leaf layer. The leaf layer may include access switches (leaf switches) that aggregate traffic from servers and connect directly into the spine or network core. Spine switches interconnect all leaf switches in a full-mesh topology between access switches in the leaf layer and the servers from which the access switches aggregate traffic. As such, in one embodiment, to ensure reliable operation of downlinks, the transceiver module 100 may be configured to operate between the server and the leaf layer. In particular, as shown in
The first optical coupler 102 may include a first input port 104A and a first output port 104B. The second optical coupler 106 may include a second input port 108A and a second output port 108B. The first input port 104A of the first optical coupler 102 may be operatively coupled to the first optical module 101, and the second input port 108A of the second optical coupler 106 may be operatively coupled to the second optical module 103. The adapter 110 may include a third input port 112A and a third output port 112B. The third input port 112A may be operatively coupled to the first optical switch 110A and the second optical switch 110B, and the third output port 112B may be operatively coupled to the leaf switch. Each port (e.g., input port, output port) of the optical module may have two optical connections configured to be used with two fiber strands, resulting in two distinct channels for the transmission and reception of data.
The third input port 112A may be operatively coupled to the first optical switch 110A and the second optical switch 110B. Similar to the ports in first optical coupler 102 and the second optical coupler 106, the third input port 112A and the third output port 112B of the adapter 110 may each have two optical connections, resulting in two distinct channels of transmission and reception of data. The optical connection for data transmission in the third input port 112A may be operatively coupled to the third prong of the first optical switch 110A, and the optical connection for data reception in the third input port 112A may be operatively coupled to the third prong in the second optical switch 110B, as shown in
The adapter 110 may also include a first inline optical power monitor PM_1 and a second inline optical power monitor PM_2, as shown in
In some embodiments, the adapter 110 may also include a power distribution element (not shown) operatively coupled to the first optical switch 110A, the second optical switch 110B, PM_1, and PM_2.
In the first configuration, when data is transmitted from the server to the leaf switch, the first optical module 101 may be configured to receive data in the form of electrical signals from the server. These electrical signals are then converted into optical signals and transmitted. These optical signals are then received by the adapter 110 via the first optical coupler 102. The data is then received by the first optical switch 110A of the adapter 110, and subsequently routed to third input port 112A. The third output port 112B of the adapter 110 may receive the data from the third input port 112A and subsequently transmit the data to the leaf switch. When data is received from the leaf switch, the adapter 110 may be configured to receive the data in the form of optical signals from the leaf switch via the third output port 112B. The second optical switch 110B of the adapter may receive the data (via the third input port 112A) and route it to the first optical module 101 via the first optical coupler 102. These optical signals are then converted into electrical signals by the first optical module 101, and subsequently transmitted to the server. In the first configuration, the second optical module 103 may remain operationally inactive, such that the transmission and reception of data is handled by the first optical module 101.
Next, as shown in block 154, the process flow includes detecting, using an adapter 110, an operational failure of the first optical module 101. As described herein, it is not uncommon for an optical module to fail during operation due to a number of reasons, causing reduced performance or unplanned downtime at the data center and resulting in significant cost to the user. During operation, the inline optical power monitors PM_1 and PM_2 continuously monitor the first optical module 101 and the second optical module 103 to determine whether they are operational. The first optical module 101 is considered operational if PM_1 is able to detect the instantaneous power of the optical signals flowing through the optical fiber connecting the first output port 104B of the first optical coupler 102 and the first optical switch 110A. Similarly, the second optical module 103 is considered operational if PM_2 is able to detect the instantaneous power of the optical signals flowing through the optical fiber connecting the second output port 108B of the second optical coupler 106 and the first optical switch 110A. At any point in time, if PM_1 stops detecting the power, the first optical module 101 may be considered to be in operational failure.
Next, as shown in block 156, the process flow includes automatically engaging the second optical module 103 in response to detecting the operational failure of the first optical module 101. In some embodiments, in response to detecting the operational failure of the first optical module 101, the adapter 110 may be configured to trigger the transceiver module 100 to switch from the first configuration of operation to a second, contingent configuration. In this regard, the adapter 110 may be configured to engage, e.g., trigger the second optical module 103 to become operationally active. In some embodiments, the adapter 110 may be configured to detect the operational failure of the first optical module 101 and subsequently trigger the switch to change from the first configuration to the second configuration using the power distribution element. In this regard, the power distribution element may be configured to receive an indication from PM_1 that no optical power is detected flowing through the optical fiber connecting the first output port 104B and the first optical switch 110A. In response, the power distribution element may generate control signals configured to automatically engage the second optical module 103. In some embodiments, instead of the adapter 110, the host, i.e., the dual-port NIC or the optical switch, may be configured to detect the operational failure. In response, the host may be configured to instruct the adapter 110 to switch from the first configuration of operation to a second, contingent configuration. To this end, the optical switches 110A and 110B in the adapter 110 may receive instructions from the dual-port NIC to trigger the switch in configuration.
Next, as shown in block 158, the process flow includes triggering a source to reroute the data from the first optical module 101 into the second optical module 103. In some embodiments, in addition to engaging the second optical module 103, the power distribution element may also be configured to transmit control signals configured to trigger the source to reroute the data.
Next, as shown in block 160, the process flow includes receiving the data from the second optical module. Once operationally active, similar to the first optical module 101, the second optical module 103 may be configured to receive data in the form of electrical signals from the server. These electrical signals are then converted into optical signals and transmitted. These optical signals are then received by the adapter 110 via the second optical coupler 106. The data is then received by the first optical switch 110A of the adapter 110, and subsequently routed to third input port 112A. The third output port 112B of the adapter 110 may receive the data from the third input port 112A and subsequently transmit the data to the leaf switch. When data is received from the leaf switch, the adapter 110 may be configured to receive the data in the form of optical signals from the leaf switch via the third output port 112B. The second optical switch 110B of the adapter may receive the data (via the third input port 112A) and route it to the second optical module 103 via the second optical coupler 106. These optical signals are then converted into electrical signals by the second optical module 103 and transmitted to the server. Thus, in the second configuration, the second optical module 103 may be operationally active, such that all network traffic from the sever is handled by the second optical module 103 instead of the first optical module 101 and transmitted to the leaf switch via the adapter 110.
In some cases, there may not always be sufficient pluggable space on the server to host an operationally inactive optical module waiting to be used only in a contingent scenario. To ensure that no optical module remains unused for any amount of time, in some embodiments, the transceiver module 100 may include two optical modules where both optical modules are operationally active. Both the optical modules are connected to a pair of 2×2 optical switches housed within the adapter. During normal operation, one optical module handles leaf layer traffic, i.e., traffic from the leaf switch to a server, while the other optical module handles spine layer traffic, i.e., traffic from the leaf switch to the spine switch. Should the optical module handling leaf layer traffic fail, the adapter detects this failure. In response, the adapter stops existing traffic received via the second optical module and triggers the source to redirect the traffic initially received via the first optical module so that it is instead received via the second optical module, thereby prioritizing the more important of the two connections.
The first optical coupler 202 may include a first input port 204A and a first output port 204B. The second optical coupler 206 may include a second input port 208A and a second output port 208B. The first input port 204A of the first optical coupler 202 may be operatively coupled to the first optical module 101, and the second input port 208A of the second optical coupler 206 may be operatively coupled to the second optical module 103. The adapter 210 may also include a third input port 212A, a fourth input port 212 that may be operatively coupled to the first optical switch 210A and the second optical switch 210B, and a third output port 212C, and a fourth output port 212D that may be operatively coupled to a leaf switch and a spine switch, respectively. Each port (e.g., input port, output port) of the optical module may have two optical connections configured to be used with two fiber strands, resulting in two distinct channels for the transmission and reception of data.
In some embodiments, the adapter 210 may be configured to operate in two configurations, such as a first configuration and a second configuration. In both configurations, the first optical module 101 and the second optical module 103 may be operationally active. The first configuration may be a default configuration of operation, and the second configuration may be a contingent configuration that is implemented when the first optical module 101 operationally fails. When such a failure is detected, existing traffic received via the second optical module is terminated and the source is triggered to redirect the traffic initially received via the first optical module so that it is instead received via the second optical module, thereby prioritizing the more important of the two connections.
Similar to the transceiver module 100 shown in
The first optical switch 210A may be configured to be used in conjunction with optical connections for data transmission. Accordingly, the first prong of the first optical switch 210A may be operatively coupled to the optical connection for data transmission of the first optical module 101 and the second prong of the first optical switch 210A may be operatively coupled to the optical connection for data transmission of the second optical coupler 206, as shown in solid lines in
The third input port 212A may be operatively coupled to the first optical switch 210A and the second optical switch 210B. In particular, the optical connection for data transmission in the third input port 212A may be operatively coupled to the third prong of the first optical switch 210A, and the optical connection for data reception in the third input port 212A may be operatively coupled to the third prong in the second optical switch 110B, as shown in
Similar to adapter 110 of transceiver module 100, the adapter 210 of transceiver module 200 may also include a first inline optical power monitor PM_1 and a second inline optical power monitor PM_2, as shown in
Similarly, when the second data is transmitted from the leaf switch to the spine switch, the second optical module 103 may be configured to receive the second data in the form of electrical signals from the leaf switch. These electrical signals are then converted into optical signals and transmitted. These optical signals are then received by the adapter 210 via the second optical coupler 206. The data is then received by the first optical switch 210A of the adapter 210, and subsequently routed to the fourth input port 212B. The fourth output port 212D of the adapter 210 may receive the second data from the fourth input port 212B, and subsequently transmit the data to the spine switch. When second data is received from the spine switch, the adapter 210 may be configured to receive the second data in the form of optical signals from the spine switch via the fourth output port 212D. The second optical switch 210B of the adapter 210 may receive the second data and route it to the second optical module 103. These optical signals are then converted into electrical signals and subsequently transmitted to the leaf switch.
Next, as shown in block 254, the process flow includes detecting, using an adapter 210, an operational failure of the first optical module 101. The first optical module 101 is considered operational if PM_1 is able to detect the instantaneous power of the optical signals flowing through the optical fiber connecting the first output port 204B and the first optical switch 210A. Similarly, the second optical module 103 is considered operational if PM_2 is able to detect the instantaneous power of the optical signals flowing through the optical fiber connecting the second output port 208B and the first optical switch 210A. At any point in time, if PM_1 stops detecting the power, the first optical module 101 may be considered to be in operational failure.
Next, as shown in block 256, the process flow includes terminating reception of the second data via the second optical module 103 in response to detecting the operational failure of the first optical module 101. In some embodiments, in response to detecting the operational failure of the first optical module 101, the adapter may be configured to trigger the switch from the first configuration of operation to a second, contingent configuration. In this regard, the adapter may be configured to terminate reception of second data by the second input port 208A of the second optical coupler 206. In some embodiments, the adapter 210 may be configured to detect the operational failure of the first optical module 101 and subsequently trigger the switch from the first configuration to the second configuration using the power distribution element. In this regard, the power distribution element may be configured to receive an indication from PM_1 that no optical power is detected flowing through the optical fiber connecting the first output port 204B and the first optical switch 210A. In response, the power distribution element may generate control signals configured to terminate reception of the second data via the second optical module 103.
Next, as shown in block 258, the process flow includes triggering a source to reroute the first data from the first optical module 101 into the second optical module 103. In some embodiments, in addition to terminating reception of the second data via the second optical module 103, the power distribution element may also be configured to trigger the source to reroute the first data into the second optical module 103. In some other embodiments, instead of the adapter 210, the host, i.e., the dual-port NIC or the optical switch, may be configured to detect the operational failure. In response, the host may be configured to instruct the adapter 210 to switch from the first configuration of operation to a second, contingent configuration. To this end, the optical switches 210A and 210B in the adapter 210 may receive instructions from the dual-port NIC to trigger the switch in configuration.
Next, as shown in block 260, the process flow includes receiving the first data from the second optical module 103. The second optical module 103 may then be adapted to receive the first data in the form of electrical signals from the leaf switch. These electrical signals are then converted into optical signals and transmitted. These optical signals are then received by the adapter 210 via the second optical coupler 206. The data is then received by the first optical switch 210A of the adapter 110, and subsequently routed to the fourth output port 212D of the adapter 210 (via the fourth input port 212B) and subsequently to the server. When data is transmitted from the server to the leaf switch, the adapter 210 may be configured to receive the first data in the form of optical signals from the server via the fourth output port 212D. The second optical switch 210B of the adapter may receive the first data (via the fourth input port 212B) and route it to the second optical module 103 via the second optical coupler 206. These optical signals are then converted into electrical signals and transmitted to the leaf switch. By rerouting the first data to the server via the second optical module 103 in response to detecting operational failure of the first optical module 101, the more important of the two connections, the connection between the server and the leaf switch, is prioritized over the connection between the server and the spine switch.

It will also be understood that the one or more computer-executable program code portions may be stored in a transitory or non-transitory computer-readable medium (e.g., a memory, and the like) that can direct a computer and/or other programmable data processing apparatus to function in a particular manner, such that the computer-executable program code portions stored in the computer-readable medium produce an article of manufacture, including instruction mechanisms that implement the steps and/or functions specified in the flowchart(s) and/or block diagram block(s).
The one or more computer-executable program code portions may also be loaded onto a computer and/or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer and/or other programmable apparatus. In some embodiments, a computer-implemented process is thus produced, such that the one or more computer-executable program code portions which execute on the computer and/or other programmable apparatus provide operational steps to implement the steps specified in the flowchart(s) and/or the functions specified in the block diagram block(s). Alternatively, computer-implemented steps may be combined with operator and/or human-implemented steps in order to carry out an embodiment of the present disclosure.
While certain exemplary embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of, and not restrictive on, the broad disclosure, and that this disclosure is not to be limited to the specific constructions and arrangements shown and described, as various other changes, combinations, omissions, modifications and substitutions, in addition to those set forth in the above paragraphs, are possible. Those skilled in the art will appreciate that various adaptations and modifications of the just described embodiments can be configured without departing from the scope and spirit of the disclosure. Therefore, it is to be understood that, within the scope of the appended claims, the disclosure may be practiced other than as specifically described herein.
