摘要
可堆叠roadm (s - roadm)已被提出用于区域性IP-over-CWDM网络。S-ROADM可以通过连接节点中不同波长的模块来构建。实验结果表明，S-ROADM可以成功地对波长进行多路复用和多路复用，并且对穿透波长没有限制，使网络具有波长透明。与S-ROADM相反，现有的固定roadm不是波长透明的。双向s - roadm也被提出，并且可以在IP-over-CWDM网络中使用双向s - roadm成功地重新配置光路。
Lightpath reconfigurations in IP-over-CWDM networks with stackable ROADMs
Stackable ROADMs (S-ROADMs) have been proposed for use in regional IP-over-CWDM networks. The S-ROADM can be constructed by connecting modules with different wavelengths required in the node. The experimental results clarified that the S-ROADM could mux and demux the wavelengths successfully, and gave no limit to the passing-through wavelengths, making the network be wavelength transparent. Contrary to the S-ROADM, the existing fixed ROADMs were not wavelength transparent. The bidirectional S-ROADMs have also been proposed, and lightpaths could be reconfigured successfully in an IP-over-CWDM network with the bidirectional S-ROADMs.
