摘　　要：介绍了一种新的波分复用无源光网络(WDM-PON)监测方案,对检测过程和故障定位过程分别进行了描述,并对其相互之间的关系进行了分析。根据监测系统的基本工作原理,在VPI软件中搭建了实验仿真平台,给出了系统仿真框图和仿真计算结果。通过对反射事件、衰减事件和断纤三类事件的模拟分析,我们可以得出模拟监测方法不但可以准确检测出光纤链路中不同的光事件,而且可以得到各类事件的详细信息。A new wavelength division multiplexing passive optical network （WDM-PON） monitoring program is introduced, and the detection process and the fault location process are described, and their relationship is analyzed. According to the basic principles of the system, an experimental simulation platform was built in VPI software and the system simulation block diagram and simulation results were given. By making simulations on the three main events of reflection events, non-reflective events and fiber cut, it can be concluded that the analog monitoring method not only can accurately detect a fiber link in different light events, but also get more information of various events.
