摘　　要：为满足山西电力数据通信业务发展需求,保证省公司层级至全省各地市分公司层级办公自动化、高清视频会议系统大颗粒数据业务传输可靠,通过建设2个层级的密集波分光传输系统,基本实现了高可靠性、大容量的现代数据通信网络建设思想。文章论述了山西电力主干光纤通信网密集波分复用系统采用的网状结构层次、业务和波长规划,介绍了数字光传送节点(Digital Transmit Node,DTN)设备组网能力和功能模块,以及网管和设备组网的设计思路,对今后建设和扩容波分通信网络具有一定参考作用。To meet the needs of Shanxi electric power data communication business development, ensure the reliability of data transmission in large granularity at provincial level and city level for office automation system and high-definition video conferencing system, this paper presents an approach to build a bi-level DWDM optical transmission system with high reliability and large capacity. This paper discusses the mesh network structure layer, service and wavelength planning used in Shanxi power optical fiber communication network DWDM system, describes DTN DWDM equipment networking capability and functional modules in detail and introduces the design idea of the network management and equipment networking, which provides some references to the future construction and expansion of the DWDM communication network.
