ROADM技术应用研究

ROADM Technology Application Research

通过分析基于波长选择开关(Wavelength Selective Switch,WSS)的可重构光分插复用器(Reconfigurable Optical Add-Drop Multiplexer,ROADM)技术特点及应用场景,并结合现网主流省内骨干及城域光传送网(Optical Transport Network,OTN)的网络架构、网络特点以及光交叉节点的配置方案,对现网采用基于光交叉连接(Optical Cross-Connec,OXC)的ROADM设备形态应用及组网策略进行分析研究。结合某省网络的实际情况,给出具体的ROADM改造部署方案及存在的相关问题。

By analyzing the technical characteristics and application scenarios of the Reconfigurable Optical Add-Drop Multiplexer(ROADM)based on the Wavelength Selective Switch(WSS),combined with the mainstream provincial backbone and metro areas of the existing network the Optical Transport Network(OTN)network architecture,network characteristics and optical cross node configuration scheme,the existing network is based on the Optical Cross-Connect(OXC)ROADM equipment form application and networking strategy analysis.Combined with the actual situation of the network in a certain province,the specific ROADM transformation deployment plan and related problems are given.
