Abstract

The invention relates to a photoelectric integrated rotation transmission system of a high speed RapidIo signal and an implementation method of rotation transmission. The system is composed of a smooth ring, a transmitting plate and a receiving plate. The smooth ring is a single mode fiber rotation connector. The transmitting plate is composed of a transmitting plate power supply module, an equalization compensation module, a first optical module and a 2-in-1 wavelength division multiplexer. The receiving plate comprises a receiving plate power supply module, a second optical module and a 1-to-2 wavelength division multiplexer. When the system works, the transmitting plate carries out electrical-to-optical conversion on a RapidIo electrical signal input by a client to send a RapidIo optical signal, and the RapidIo optical signal is transmitted to the receiving plate through the smooth ring. The receiving plate receives the RapidIo optical signal and completes optical-to-electrical conversion and electrical-to-optical conversion to send the RapidIo optical signal, and the RapidIo optical signal is transmitted back to the transmitting plate through the smooth ring. The transmitting plate receives the RapidIo optical signal and completes optical-to-electrical conversion to output the RapidIo electrical signal to the client. Rotation transmission and full duplex communication of the high speed RapidIo signal are completed. According to the invention, the requirement of rotation transmission of the high speed RapidIo signal of a photoelectric detecting device in the monitoring field is met.
