摘要： In an apparatus and method for troubleshooting a transmission system comprising optical line amplifiers (OA), optical reflections can be detected irrespective if a data signal is present or absent. Each OA is equipped with a self-stimulation signal detection unit for generating a low frequency local code unique to the transmission system and dithering the outgoing signal in a controlled manner with the local code. Each OA attempts to detect its local code in the incoming signal by comparing the energy of the transmitted and received dithers. The presence of the local code in the incoming signal initiates alarms which unequivocally identify the faulted OA. Each OA selects its local code out of a bank of local codes, according to a priority scheme and re-selects its local code in case of conflicts.

摘要翻译： 在用于对包括光线路放大器（OA）的传输系统进行故障排除的装置和方法中，无论数据信号是否存在，都可以检测光学反射。 每个OA配备有自刺激信号检测单元，用于产生传输系统唯一的低频本地码，并以受控方式用本地码对出局信号进行抖动。 每个OA尝试通过比较发送和接收抖动的能量来检测输入信号中的本地代码。 输入信号中存在本地代码会启动明确识别故障OA的警报。 每个OA根据优先级方案从一组本地代码中选择其本地代码，并在发生冲突时重新选择其本地代码。

摘要： A fast means of detecting that a fiber has been disconnected at one end of a bidirectional optical amplifier by monitoring for several signature effects simultaneously. Upon detection of a loss of signal, the pump laser in the corresponding direction is shut off quickly to prevent oscillation from occurring should the other end of the amplifier be subsequently disconnected.
