摘要
介绍光时域反射仪的工作原理,以及光纤中发生反射事件和非反射事件时光时域反射仪测得的各种轨迹,讨论光时域反射仪脉冲宽度的设定和光纤长度的计算,为光纤测量提供理论依据。
The basic principle of OTDR is introduced,also including the test of the trace of reflecting event and not-reflecting event in the fiber through OTDR, width enactment and calculation on fiber length are illustrated for OTDR, that is theory dependent for fiber measurement.
