The photoelectric transceivers on the network card port on the server side are all single-channel devices, and the electrical channel of the server port is also a single-channel port, so there is no room for adjustment. Switch ports are ports with a fixed number of electrical channels. For the optoelectronic transceiver device on the switch port, the number of electrical channels of the optoelectronic conversion chip inside the optoelectronic transceiver device is consistent with the number of electrical channels of the switch port, one-to-one correspondence, and the sending optical channel and the receiving optical channel of the optoelectronic transceiver device on the switch are both Not adjustable. In a system, the Y-Cable can be a split fiber for part of the AOC package. The switch port rates are 10G, 25G, 40G, and 100G, and the server-side network card port rates are 10G, 25G, 40G, and 100G.

In the system, it includes different package types of optoelectronic transceivers, Y-Cable AOCs with different rates or one-point-multiple AOCs. For example, QSFP28 one-to-two SFP28 AOC (QSFP28 photoelectric transceiver theoretically supports 4×25G electrical channel port and optical channel port, but in Y-Cable application, only 2 channels are used, which becomes 2×25G Electrical channel ports and optical channel ports; SFP28 photoelectric transceivers theoretically support 1×25G electrical channel ports and optical channel ports. In Y-Cable applications, the solution remains unchanged, using two SFP28 modules and two optical channels of QSFP28 modules. channel interconnect). QSFP+ one-to-two SFP+AOC AOC (QSFP+ photoelectric transceiver theoretically supports 4×10G electrical channel port and optical channel port, but in Y-Cable application, only 2 channels are used, which becomes 2×10G Electrical channel ports and optical channel ports; SFP+ photoelectric transceivers theoretically support 1×10G electrical channel ports and optical channel ports.

QSFP56 one-to-two SFP56AOC AOC (QSFP56 photoelectric transceiver theoretically supports 4×50G electrical channel port and optical channel port, but in Y-Cable application, only 2 channels are used, which becomes 2×50G electrical channel Port and optical channel port; SFP56 module theoretically supports 1×50G electrical channel port and optical channel port, in Y-Cable application, the scheme remains unchanged, using 2 SFP56 modules to interconnect with 2 optical channels of QSFP56 module).

Among them, SFP+/SFP28/QSFP+/QSFP28/QSFP56/QSFP-DD are respectively used to indicate different package types of optoelectronic transceivers, which are not limited in this specification.

FIG. 1 is a schematic diagram showing the connection between an optoelectronic transceiver device and a switch port in the related art. In the related art, a QSFP28 optoelectronic transceiver is taken as an example. As shown in FIG. 1 , the switch port 11 is connected with a golden finger 12 , and the golden finger 12 is used to transmit the electrical signal output by the switch port 11 . The switch port 11 includes a transmit electrical channel and a receive electrical channel, wherein the transmit electrical channels of the switch port 11 include TX1, TX2, TX3, and TX4, and the receive electrical channels of the switch port 11 include RX1, RX2, RX3, and RX4.

The photoelectric transceiver 10 includes a photoelectric conversion chip, and the photoelectric conversion chip includes a transmitting electrical channel and a receiving electrical channel corresponding to the switch port 11 . The transmit electrical channels of the photoelectric conversion chip include TX10, TX20, TX30, and TX40, and the receive electrical channels of the photoelectric conversion chip include RX10, RX20, RX30, and RX40. The photoelectric conversion chip also includes a transmitting optical channel and a receiving optical channel.

The photoelectric conversion chip includes a transmitter 101, a receiver 102 and a controller 103. The controller 103 connects the transmitter 101 and the receiver 102. The controller 103 is used to control the transmitter 101 to receive electrical signals and convert them into optical signals, and then output them through an optical fiber. , the controller 103 is also used to control the receiver 102 to receive the optical signal and convert it into an electrical signal to output to the switch port 11 . Controller 103 may be a microprocessor.

The transmitter 101 is connected to the golden finger 12 and the controller 103 , and includes a transmitter clock recovery module 1010 , a driver module 1011 and a transmitter module 1012 . The sending end clock recovery module 1010 is used to receive the electrical signal sent by the switch port 11, the driving module 1011 can be a laser diode driver, and is used to drive the clock recovery module 1010 to convert the electrical signal into an optical signal, and the sending module 1012 can be a laser, using for sending optical signals through optical fibers.

The receiver 102 is connected to the cheat 12 and the controller 103 , and includes a receiving module 1020 , a converting module 1021 and a receiving end clock recovery module 1022 . The receiving module 1020 can be a photosensitive element for receiving optical signals, the conversion module 1021 is used to convert the optical signals received by the receiving module 1020 into electrical signals and output them, and the receiving end clock recovery module 1022 is used to receive electrical signals and transmit them to Switch port 11.

Referring to Figure 1, when 100G QSFP28 one-to-two SFP28 AOC is applied in the system, the physical port of the switch contains 4 electrical channels (4×25G), but only two of them are selected for practical application, that is, 2×25G reduces For high-speed applications, the network card port on the server side is two 25G SFP28 physical ports, each physical port contains 1 electrical channel (1×25G). The photoelectric conversion chip inside the QSFP28 photoelectric transceiver can only enable two channels of the electrical channel of the switch. For example, after the switch port 11 uses the electrical channels of TX1, TX2, RX1, and RX2 fixedly, the photoelectric conversion chip of the photoelectric transceiver 10 can only enable the corresponding electrical channels of TX10, TX20, RX10, and RX20. If the electrical channel of the switch port 11 is fixed, after the Y-Cable or the one-point-multiple AOC design is finalized and applied, the optoelectronic transceiver 10 can only enable the fixed optoelectronic channel. Because the optoelectronic transceiver device 10 of the switch port 11 and the optical channel port connected to the network card port on the server side are fixed channels, that is, the optical channel inside the optoelectronic transceiver device 10 does not support switching, when the electrical channel of the switch port 11 consists of TX1, TX2, RX1, If RX2 is replaced with TX3, TX4, RX3, RX4, the current Y-Cable AOC can only enable TX30, TX40, RX30, RX40 of the photoelectric conversion chip, because the photoelectric conversion chip channels inside the photoelectric transceiver are in one-to-one correspondence. Therefore, the Y-Cable AOC cannot continue to enable the TX10, TX20, RX10, and RX20 channels of the optical channel, and the AOC cannot be connected normally.

In practical applications, when the speed of the switch port 11 is reduced by half, the other half of the electrical channels are not utilized, resulting in waste. At the same time, because there are many switch ports 11, if one of the electrical channels of the used switch port 11 fails, the switch port 11 cannot be used continuously. If the switch needs to be repaired, the entire switch must be replaced and repaired, and the maintenance cost is very high. In addition, when the electrical channel of the switch port 11 or the electrical channel of the optoelectronic transceiver 10 is faulty or replaced, the entire system cannot be communicated normally.

This specification proposes an optoelectronic transceiver device and a control method thereof, which aim to flexibly adapt the electrical channel of the optoelectronic transceiver device and the electrical channel of the switch, and can ensure the normal communication of the entire system.
