摘要
介绍了可重构光分插复用器(reconfigurable optical add/drop multiplexer,ROADM)网络的发展历程、ROADM技术方案以及国内ROADM网络的部署情况。全面阐述了ROADM关键技术的发展方向,包括光交叉连接(optical cross-connect,OXC)设备、高维度波长选择开关(wavelength selected switch,WSS)、波长无关/方向无关/竞争无关ROADM(colorless/directionless/contentionless ROADM,CDC-ROADM)、400 Gbit/s FlexGrid ROADM、下一代波长交换光网络(next-generation wavelength switched optical network,WSON2.0)智能控制平面技术。分析了现有ROADM网络应用场景与技术发展趋势,展望了ROADM全光交换网络未来发展前景。
The development history of reconfigurable optical add/drop multiplexer(ROADM)networks,ROADM technical solutions and the deployment of ROADM networks in China were described.And the development direction of the key technologies of ROADM was described,including optical cross-connect(OXC),high dimensions wavelength selected switch(WSS),colorless/directionless/contentionless ROADM(CDC-ROADM),400 Gbit/s FlexGrid ROADM,and next-generation wavelength switched optical networks(WSON2.0)intelligent control plane technologies.The existing ROADM network application scenarios and technology development trend were analyzed,and the future prospects of the ROADM all-optical switching network were looked forward to.
