基于双向OTDR测试的光传输网实时监测系统

基于现有的光信号处理技术、网络技术以及OTDR等设备设计并实现光传输网实时监测系统,提出基于双向OTDR测试来解决OTDR在长距离测量光缆线路时动态范围受限的问题,同时结合采用GIS等技术开发的光缆线路管理系统(FMMIS),进行对光传输网络的实时监测,实现了光纤中断故障的自动精确定位。

Optical transmission network real-time monitoring system based on Bi-directional OTDR

Based on existing optical signal processing technology,network technology,and OTDR equipment design and real-time monitoring system of the optical transmission network,this paper proposed to solve the problem of the OTDR dynamic range is limited in the long distances of fiber optic cable line based on bi-directional OTDR testing,while a combination of GIS and other technology development of fiber optic cable line management system(FMMIS),real-time monitored the optical transmission network,to achieve automatic and accurate positioning of the fiber interrupt fault.
