摘　　要：为了解决既有省际干线组网光层穿通比例偏低、建网投资高级电路调度效率整体偏低等现实问题,提出将可重构光分插复用器(Reconfigurable Optical Add-Drop Multiplexer,ROADM)和光传送网(Optical Transport Network,OTN)技术用于干线传输网络建设。通过对比分析ROADM、OTN这2种组网方案的优势和弊端,为提升区域ROADM网络规划水平提出可行性建议与方法,提高网络波道利用率,增加业务路由的多样性,确保网络能在更低时延的路由情景下安稳运行。In order to solve the practical problems such as the low ratio of optical layer penetration in existing inter-provincial trunk networks and the overall low scheduling efficiency of advanced circuits for network construction investment,the technologies of Reconfigurable Optical Add-Drop Multiplexer(ROADM)and Optical Transport Network(OTN)are proposed for trunk transmission network construction.By comparing and analyzing the advantages and disadvantages of ROADM and OTN,this paper puts forward feasible suggestions and methods to improve the planning level of regional ROADM network,improve the utilization rate of network channels,increase the diversity of business routes,and ensure the stable operation of the network under the routing scenario with lower delay.
