OTDR测试在光纤通信工程应用中误差分析及对策

光纤通信由于传输频带高,信息量大、保密性好、重量轻体积小,中继段长等优点得到了广泛的应用。在我国,长途网及市话传输网基本实现光纤传输。OTDR是光纤通信系统工程应用中最重要的测试仪表,光纤衰减、长度的测量、光纤接续、中继测量及故障分析等等都离不开OTDR测试。本文针对OTDR的测试和其在工程应用中常见误差分析及对策做些探讨。

Analysis on Error Measurement of OTDR and Its Countermeasure in Fiber Communication System

The applications of fiber communication grow rapidly because of it's higher frequency bandwidth,abundant information,better confidentiality,longer relay distance and light weight.Today in China,long distance and local call network has been accomplished with fiber optic cables,and the FTTH is the next.Of all the measure instruments,OTDR is a most important one.It is necessary in the measurement of fiber length,loss and system failure.This article makes some introduction on OTDR operation,its common error mea...
