Optical fiber link channel monitoring system

The invention discloses an optical fiber link channel monitoring system, and the system comprises a network management system and a plurality of optical transmission devices. Two ends of the main optical fiber channel and the standby optical fiber channel of two adjacent optical transmission devices are respectively connected with an optical fiber channel monitoring device; and the optical fiber channel monitoring devices are respectively in real-time communication with the network management system through a data network. According to the invention, the optical fiber link channel is monitoredand controlled through the network management information of the optical fiber communication system, so that the repeated monitoring of the state of the optical fiber link is avoided, the technical requirements of a station end monitoring device are reduced, and the reliability of the system is improved. 本发明公开了一种光纤链路通道监控系统，包括：网管系统和若干光传输设备；在相邻两个光传输设备的主用光纤通道和备用光纤通道的两端分别连接光纤通道监控装置；所述的光纤通道监控装置分别通过数据网与网管系统进行实时通信。本发明通过光纤通信系统网管
