Description

光纤线路路由查找方法、故障检测方法及检测系统 技术领域
本发明涉及光纤线路路由查找及故障检测方法，涉及光纤线路传输中的各个连接环节中的路由查找以及故障检测，覆盖光纤干、支线传输路由、电信机房线路路由、FTTx光纤到终端线路路由的查找及故障检测。
背景技术
随着光纤通信的迅猛发展，光纤线路日益增多，由于光缆铺设前期技术受限并未实现科学的光纤路由管理，造成光纤线路路由混乱，涉及从干线到末端用户的各个环节，尤其是机房ODF架管理，纸质标签不规范、丢损、配线信息不准、维护人员更迭等给后期维护带来了极大隐患。当线路发生故障或差错时，线路路由的查找非常繁琐，费时费力，根本无法满足客户对网络维护的需要，此问题也成为光通信界的难题。
当前在光纤路由查找方面，使用最普遍的是加拿大EXFO公司生产的“光纤纤序查找仪”，该设备由一个发射器101和一个接受器102组成，参照图5所示，工作时把发射器101固定在需要查找路由的光缆上，发射器弯曲光缆把发射头压紧在光缆上，发送信号；接受器102在一簇未知光缆中对每个光缆进行弯曲固定，寻找有信号的光缆，最终定位光缆。此方案由于需要对查找目标进行弯曲压紧固定，操作时间长，而且设备昂贵，仅适合于查找少量光缆路由，或验证现有光缆路由，不适合大量的光纤路由查找。
在光纤配线架及端口智能化管理系统方面，大多厂家提出了基于RFID的光纤智能ODF管理方法，此方法仅适于新建机房路由。通过附加在适配器座上的RFID识别器和插头上的RFID标签,对光纤路由进行一一对应并进行电子录入。此方法仅仅起到替代纸质标签的作用，无法对老机房进行整治，对接续点状态也无法进行监控，在标签丢失、识别器损坏或系统故障或崩溃时，数据恢复的工作量极大，维修时间长，无法满足运营商对光纤路由管理的需要。由于涉及光纤跳纤、ODF配线托盘等，使用时需要各个厂商多环节支持，普及困难。
