一种WDM光缆传输性能自动监测系统

光缆线路是传输光信号的通道,是光纤通信不可分割的一部分,但由于其本身及外在因素的影响,所造成的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.介绍了一种光缆监测系统的工作原理、硬件构成及基本功能,与此同时还给出了一个检测的具体实例.

A WDM System of Auto-monitoring Transmission Performance for Optical Cable

Optical cable lines are the channels used to transmit optical signals,and are the indivisible part of optical communications. But the loss caused by the line obstacles of optical cable is unexpected and heavy because of its interior and exterior factors. So it is necessary to build an optical cable monitoring system to realize real time and online auto-monitoring transmission performance of optical cable. This paper introduces the operation principle, chief hardware composition and function of OAMS,at the same time gives an example of monitoring by OAMS.
