Description

technical field [0001] The invention relates to the field of communication technology, in particular to a photoelectric conversion rate self-matching system and method. Background technique [0002] With the rapid development of communication technology, the network speed is getting faster and faster, and the application range of photoelectric conversion is getting wider and wider. A photoelectric converter (that is, a photoelectric transceiver) is a device for data transmission between an electrical signal medium and an optical fiber data link. photoelectric signal conversion. That is, the photoelectric converter receives the electrical signal, converts the electrical signal into an optical signal, and then transmits it through the optical fiber link; similarly, the photoelectric converter receives the optical signal, converts the optical signal into an electrical signal, and then transmits it through the twisted pair . Optical-to-electrical converters are generally used...

Problems solved by technology

[0003] In the existing technology, since the optical transmission standard does not define an effective speed matching mechanism, it is impossible to adaptively adjust the transmission rate when the data sending end and the data receiving end establish a communication connection (Link).

For example, the transmitter currently uses a transmission rate of 1000M to transmit signals, while the receiver currently uses a transmission rate of 100M. The transmission standards adopted by the two parties are different, resulting in the failure of the transmitter and receiver to establish a communication connection on the application layer.

Usually, the user needs to manually configure the physical layer chips of both sides, so that the data sending end and the data receiving end switch to the same transmission standard at the same time, and the link will be established, resulting in poor user experience. Therefore, it is urgent to design a solution to solve the above problems. A photoelectric conversion rate self-matching system and method to meet the needs of actual use
