Abstract As the abnormal link of the optical fiber multiplexing channel occurs, maintenance staff use traditional detection method which is time-consuming and laborious. Meanwhile, the optical fiber channel message is not recorded, so the instantaneous anomaly cannot be tracked. For this application scenario, channel anomaly detection method is studied in this paper. Based on the analysis of traditional detection methods, this paper puts forward a scheme for online identification of abnormal interval of optical fiber channel, further expounds the key technology and carries out the development and testing of devices to satisfy the requirements of fiber channel anomaly analysis that can be located and traced. The results show that this scheme can identify channel anomalies and locate abnormal regions online, and can further trace the causes of anomalies through message recording. The scheme proposed in this paper can effectively improve the efficiency of abnormal overhaul of fiber multiplexing channels and provide a favorable basis for analyzing the causes of channel anomalies. It has good economy.
