摘要
可重构光分插复用(ROADM)设备可以通过软件实现远程节点上、下路和直通波长的配置。文章首先介绍了ROADM设备结构的演进过程,然后通过比较基于波长选择开关(WSS)的结构的ROADM设备,采用不同逻辑实现方式获得了不同特性,最后探讨了WSS的实现技术。
ROADM enables the configuration of drop, add and express wavelengths at remote nodes via software control. In this paper, the evolution of ROADM technologies is first presented. Then, WSS-based ROADM with different architectures are compared and different performances obtained by different logical ways of implementation. Finally, approaches for WSS implementation are discussed.
