In order to transmit relay protection signal accurately in optical fiber communication network,channel equalization configuration and adaptive relay control of relay protection signal in optical fiber communication network are needed. An accurate transmission method of relay protection signal in optical fiber communication network based on time-varying multipath fading suppression and adaptive beamforming is proposed,and the relay channel equalization model of optical fiber communication network is constructed. The fiber Porter equalization technique is used to design the relay transmission link equalization in optical fiber communication network. Aiming at the time-varying multipath attenuation of the communication channel,the multipath suppression is carried out by the continuous tap processing method of the electric signal. According to the time-varying multipath fading loss of the channel,the optimal baud interval sampling of relay protection signal is carried out,and the multipath fading suppression method is used to compensate the signal and filter the interference in the communication channel of optical fiber network. Adaptive beamforming and accurate transmission of relay signal are realized. The simulation results show that the proposed method has the advantages of good accuracy,strong anti-jamming ability and good channel equalization in the transmission of relay protection signals in optical fiber communication networks.
