摘要
本文分析了在线监测和备份保护对PON网络的意义,并提出了一种新的采用光时域反射仪(OTDR)和光开关的PON网络在线监测和保护方案。实验表明,该方案可以同时实现对PON网络的在线监测和对馈线段的保护。
A novel online monitoring and protection scheme based on Optical Time-Domain Reflectometer (OTDR) and optical switches is proposed. In the experiment, online monitoring as well as the protection of feeder fiber can be achieved.
