Abstract

本发明提供一种分布式拉曼光放大器的断纤检测方法、装置及系统,发生断纤时,断纤处输入信号光的功率迅速下降,断纤位置与放大器距离较远时,由于输入信号光减小,导致剩余光纤中输入信号光对泵浦光的消耗减小,光纤中剩余的泵浦光功率增加,使放大器的实际增益值增加,放大器的增益锁定功能发生作用,降低泵浦光的泵浦功率,维持放大器的增益基本不变,放大器输出光功率随输入光功率的减小而迅速地下降,当输出光信号的功率下降到低于输出光信号的预设功率时,判定断纤;断纤位置与光泵浦距离较近时,由于断纤位置与光泵浦距离近,泵浦光无法对输入光信号有效放大,输出光信号的功率会因为断纤迅速下降,当输出光功率低于预设功率时,判定断纤。
