摘　　要：配线架后端的光纤跳线的保护薄弱,在长期使用过程中,易造成通信故障甚至事故,对其进行有效监测和故障分析具有现实意义。本文基于波分复用技术完成各种信号的综合和分离,再借鉴光栅型光波分复用器的原理开发设计了一种光配线设备线路感测元件。把感测元件串联在线路中,再通过OTDR即可实现对配线架跳线的实时在线监测,从而提供了一种确保电力线路中通信系统可靠、有效、安全的运维手段。In the process of long-term use, the protection of the jump line on the fiber distribution frame is weak, which has caused the communication failure and accidents. So the effective monitoring and fault analysis has a realistic significance. This article is based on WDM technology that wavelength are independent of each other. WDM technology can complete different signal transmission, synthesis and separation of various kinds of signal; Reference grating type optical wavelength division multiplexer, designing the fiber bragg brating Line tracker, by OTDR for real-time online monitoring of distribution frame jumper, provides a way to ensure the security of the communication system, efficient and reliable.
