光纤自动切换保护系统的应用探讨

Application of automatic switching optical fiber protection system

分析光纤自动切换保护系统的原理,以我公司为例,在光传输网络主要路由上,接入光纤自动切换保护器,利用保护器构建出光纤保护网络,当被保护的光纤发生故障中断或者衰耗增大导致通信传输质量下降时,光纤线路自动切换保护技术却能使网络进行实际切换,用恢复机制作为第二道防线对付网络范围的故障和失效,恢复通信的畅通,从而增强了我公司通信网络的可靠性。

Analysis of fiber-optic system automatically switches to protect the principle, In my company as an example：In the optical transmission network on the main route,Automatic protection switching using optical fiber,Use of these devices to build the network cable protection, When the working fiber loss increases lead to lower quality or traffic blocking occurs when the working fiber,the system in real time automatically from the optical transmission system switches to the backup optical fiber work to restore communication,Achieve the synchronization cable line protection switching.Thus greatly enhancing the reliability of communication systems.
