基于模块化多功能结构的光纤链路监测仪优化设计

摘要

本文主要针对基于 OTDR 技术的光纤链路监测仪的结构优化设计。在同一光纤链路检测仪中实现多型号OTDR 模块的兼容，通过替换 OTDR 模块实现不同精度和成本的多种组合，采用光开关的模块化能够快速地满足20路到40路光纤链路的多时域监测。通过与网管系统的对接将接入网与传输网的故障点范围上传到手持终端的线路地图中，实现快速的故障预警、定位与修复，减少不必要的派单，节省人力成本的投入。%This article mainly aims at the optimization design of the structure of the fiber optic link monitor based on OTDR. It can realize the compatibility of various OTDRS in the same fiber link detector. By replacing OTDR module, it can implement a variety of combination of different precisions and costs. It also can quickly meet the more time mon-itoring of 20 to 40 road optical fiber links using the optical switch modular. Through the dock with the network man-agement system, the scope of fault point of access network and transmission network can be uploaded to the handset route map, to achieve fast fault warning, positioning and repairing, reducing unnecessary single and saving the cost of human activity.
