In the current data center switch and server interconnection system, the entire physical link channel includes a switch port, an optoelectronic transceiver device (the single device with the highest rate in the Y-Cable) on the switch port, an optoelectronic transceiver device (the remaining devices in the Y-Cable) on the server-side network card port, and a server port. The photoelectric receiving and transmitting devices on the server side network card port are all single-channel devices, the electric channel of the server port is also a single-channel port, and no adjustable space exists. The switch port is a port with a fixed number of electric channels. For the photoelectric transceiving device on the port of the switch, the number of the electric channels of the photoelectric conversion chip in the photoelectric transceiving device is consistent with that of the electric channels of the port of the switch, and the electric channels correspond to each other one by one, and the transmitting optical channel and the receiving optical channel of the photoelectric transceiving device on the switch are not adjustable. In the system, the Y-Cable may be a two-in-one optical fiber used as part of the AOC package. The port rates of the switches are 10G, 25G, 40G and 100G, and the port rates of the server-side network cards are 10G, 25G, 40G and 100G. Here G (full-length Gigabit), 100G denotes a 100Gigabit/s transmission rate, and other numbers plus G are used in this specification to denote different transmission rates.

In the system, different packaging types of the optoelectronic transceiver devices, different rates of Y-Cable AOC or one-to-many AOC are included. For example, QSFP 28-one-in-two SFP28 AOC (QSFP28 optoelectronic transceiver theoretically supports 4 × 25G electrical channel port and optical channel port, but in Y-Cable application, only 2 channels are selected for use and become 2 × 25G electrical channel port and optical channel port, SFP28 optoelectronic transceiver theoretically supports 1 × 25G electrical channel port and optical channel port, in Y-Cable application, the scheme is kept unchanged, and 2 SFP28 modules are respectively used to be interconnected with 2 optical channels of QSFP28 module). QSFP + one-to-two SFP + AOC (QSFP + optoelectronic transceiver theoretically supports 4X 10G electrical channel port and optical channel port, but in Y-Cable application, only 2 channels are selected for use and become 2X 10G electrical channel port and optical channel port, SFP + optoelectronic transceiver theoretically supports 1X 10G electrical channel port and optical channel port, in Y-Cable application, the scheme is kept unchanged, and 2 SFP + modules are respectively interconnected with 2 optical channels of QSFP + modules). QSFP56 one-to-two SFP56 AOC (QSFP56 optoelectronic transceiver theoretically supports 4 × 50G electrical channel port and optical channel port, but in Y-Cable application, only 2 channels are selected for use and become 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 is kept unchanged, and 2 SFP56 modules are respectively interconnected with 2 optical channels of FP QS 56 module). In addition to this, there are many applications of 400G, 800G, etc. rate Y-Cable AOC or one-to-many AOC.

According to the architecture of the system, the interconnection between the switch and the server usually includes 10G SFP + to 10G SFP + direct AOC, 40G QSFP + to 40G QSFP + direct AOC, 40G QSFP + one-to-four 10G SFP + AOC (40G optoelectronic transceiver is inserted in the switch port, 4 10G optoelectronic transceiver is inserted in the server-side network card port), 25G SFP28 to 25G SFP28 direct AOC, 100G fp28 one-to-four 25G qsp 28 AOC (100G optoelectronic transceiver is inserted in the switch port, 4G 25G optoelectronic transceiver is inserted in the server-side network card port), and 100G QSFP28 to 100G QSFP28 direct AOC. However, in an application scenario, the system further includes Y-Cable AOCs such as 40G QSFP + one-to-two 10G SFP + AOC (40G optoelectronic transceiver is inserted into a switch port, 2 10G optoelectronic transceiver is inserted into a server-side network card port, and the switch port is slowed down to 20G and only uses 2 electrical channels), 100G QSFP28 one-to-two 25G SFP28 AOC (100G optoelectronic transceiver is inserted into a switch port, 2 25G optoelectronic transceiver is inserted into a server-side network card port, and the switch port is slowed down to 50G and only uses 2 electrical channels). The SFP +/SFP28/QSFP +/QSFP28/QSFP56/QSFP-DD are respectively used to indicate package types of different optoelectronic transceiving devices, and are not limited in this specification.

Fig. 1 is a schematic diagram illustrating the communication between an optoelectronic transceiver and a switch port according to the related art. In the related art, an optical transceiver device of QSFP28 model is taken as an example. As shown in fig. 1, a gold finger 12 is connected to the switch port 11, and the gold finger 12 is used for transmitting the electrical signal output by the switch port 11. The switch port 11 comprises a transmit electrical path and a receive electrical path, wherein the transmit electrical path of the switch port 11 comprises TX1, TX2, TX3 and TX4, and the receive electrical path of the switch port 11 comprises RX1, RX2, RX3 and RX 4.

The optoelectronic transceiver 10 includes an optoelectronic conversion chip, and the optoelectronic conversion chip includes a transmitting electrical channel and a receiving electrical channel corresponding to the switch port 11. The transmitting electric channels of the photoelectric conversion chip comprise TX10, TX20, TX30 and TX40, and the receiving electric channels of the photoelectric conversion chip comprise RX10, RX20, RX30 and RX 40. The photoelectric conversion chip also comprises a transmitting light channel and a receiving light channel.

The photoelectric conversion chip comprises 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 for controlling the transmitter 101 to receive an electrical signal and convert the electrical signal into an optical signal, and then output the optical signal through an optical fiber, and the controller 103 is also used for controlling the receiver 102 to receive the optical signal and convert the optical signal into an electrical signal to output the electrical signal to the switch port 11. The controller 103 may be a microprocessor.

The transmitter 101 connects the golden finger 12 with the controller 103, and includes a sending-end clock recovery module 1010, a driving module 1011, and a sending module 1012. The transmitting end clock recovery module 1010 is configured to receive an electrical signal transmitted by the switch port 11, the driving module 1011 may be a laser diode driver and configured to drive the clock recovery module 1010 and convert the electrical signal into an optical signal, and the transmitting module 1012 may be a laser and configured to transmit the optical signal through an optical fiber.

The receiver 102 is connected to the golden finger 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 may be a photosensitive element, and is configured to receive an optical signal, the converting module 1021 is configured to convert the optical signal received by the receiving module 1020 into an electrical signal and output the electrical signal, and the receiving-end clock recovery module 1022 is configured to receive the electrical signal and transmit the electrical signal to the switch port 11.

Referring to fig. 1, when a 100G QSFP 28-one-to-two SFP28 AOC is applied in a system, a switch physical port includes 4 electrical channels (4 × 25G), but in practical application, only two applications, namely, a 2 × 25G speed reduction application, are selected, and a server-side network card port includes two 25G SFP28 physical ports, each of which includes 1 electrical channel (1 × 25G). The photoelectric conversion chip in the QSFP28 photoelectric transceiver only enables two paths of the electric channels of the switch. For example, after the switch port 11 fixedly uses the electrical channels of TX1, TX2, RX1, and RX2, the optical-to-electrical conversion chip of the optical-to-electrical transceiver device 10 can only enable the corresponding electrical channels of TX10, TX20, RX10, and RX 20. If the electrical channel of the switch port 11 is fixed, when the Y-Cable or the one-to-many AOC design is fixed and applied on the line, the optoelectronic transceiver 10 can only enable the fixed optical channel. Because the optical transceiver device 10 of the switch port 11 and the optical channel port connected to the server-side network card port are fixed channels, that is, the optical channels inside the optical transceiver device 10 do not support switching, when the electrical channels of the switch port 11 are changed from TX1, TX2, RX1, RX2 to TX3, TX4, RX3, RX4, the current Y-Cable AOC can only enable the TX30, TX40, RX30, RX40 of the photoelectric conversion chip, because the photoelectric conversion chip channels inside the optical transceiver device are in one-to-one correspondence, the Y-Cable AOC cannot continue to enable the TX10, TX20, RX10, RX20 channels of the optical channels, and at this time, the AOCs cannot be normally connected.

In practical applications, when the speed of the switch port 11 is reduced by half, the other half of the electrical path is not utilized, which causes waste. Meanwhile, because there are more switch ports 11, if one of the electrical paths of the used switch port 11 fails, the switch port 11 cannot be used continuously. If the whole machine of the exchanger needs to be replaced and maintained for maintenance, the maintenance cost is very high. In addition, when the electric channel of the switch port 11 or the electric channel of the optoelectronic transceiver 10 is failed or replaced, the whole system cannot be normally connected.

Fig. 2 is a schematic diagram illustrating an embodiment of an optoelectronic transceiver device according to the present disclosure. In the embodiment shown in fig. 2, the opto-electronic transceiver 20 is applied to the switch 21. The optoelectronic transceiver 20 includes a transmitting unit 200, a receiving unit 201, a switching unit 202, and a control unit 203.

When a fault occurs, the whole photoelectric transceiver 20 does not need to be replaced, so that the cost is reduced, and the flexibility and the usability are improved.

When a fault occurs, the whole photoelectric transceiver 20 does not need to be replaced, so that the cost is reduced, and the flexibility and the usability of the photoelectric transceiver 20 are improved.
