一种DWM光缆传输性能自动监测系统

An WDM Optical Cable Trasmision Performance Artomatic Monitoring System

光缆线路是传输光信号的通道 ,是光纤通信不可分割的部分 ,但由于其本身的及外在的因素造成通信中断带来的经济损失是重大的。因此 ,有必要建立一个可实现实时、在线自动监测光缆传输性能的监测系统。在介绍一种光缆监测系统的工作原理。

Optical cable lines are the channels which are used to transport optical signals ,and the indiscerptible part of optical communications.But the loss caused by the line obstacles of optical cable is unexpected for the using developments because of its interior and exterior factors .So it is necessary to brild an optical cable monitoring system which realize real time and online auto monitoring transmission performance of optical cable .This paper introduces the operation principle,chief hardware composing and function of OAMS,at the same time gives a inspect example by OAMS.
