光时域反射仪测试范围与光纤线路测试精度分析

Analysis of Relations between Optical Time Domain Reflectometer's Survey Range and Accuracy in Optical Fiber Telecommunication

在光缆线路的施工维护中 ,光时域反射仪是不可缺少的测试仪器。在论述光时域反射仪工作原理的基础上 ,对光时域反射仪的测量范围和测量精度的关系进行了分析。

Optical Time Domain Reflectometer(OTDR) is indispensible for line's construction or maintenance in optical fiber telecommunications enginneering. This paper discusses OTDR's working theory , then analyses the relations between it's survey range and accuracy.
