对城域光缆传输物理双路由保护问题的讨论
摘要
城域光缆线路常会受到外力的作用而阻断
文章讨论了几种光缆传输物理双路由保护方式
其中由1/2分路器、1×2光开关和WDM组成的互保传输方式是依据城域光缆线路传输特点提出的一种设想
可供运行维护部门和有关商家做进一步的研究、探讨、实验。
Abstract
The metro area fiber cable links are broken off frequently because of external forces exerted on them. The article discusses some mutual protection ways of fiber cable links by physical two tours. One of them is an assume that mutual protection transmission system makes up of 1/2 branching devices
1/2 optical switches and WDM based on the feature of metro area fiber cable links. It is desired that moving and maintenance branches and firms concerned make more studies
