摘要
简单介绍了光环形网的几类保护形式和典型的单双向 OADM结构 ,并进一步分析了单双向节点构成的混合环网的线路保护和通道保护以及双向节点的混合保护 。
The paper introduce some kinds of protection type of optical ring networks and typical unidirectional and bi directional OADM node, the paper also analyses the line protection and channel protection of the optical ring the mix the unidirectional and bi directional OADM node and mixing protection, we also analyzes the integrate control of the node skimpily.
