摘要
为满足"十三五"期间数据骨干网万兆上联需求以及智能电网业务的发展需要,需建设具备高速率、多业务、大宽带的通信传输网络。文章阐述了100G OTN系统中正交四进制相位调制、相干接收、软判决纠错编码接收等关键技术,分析了100G OTN关键技术在大容量、长距离光传输网中的可行性应用,提出了其在电力通信大容量光传输网中的技术应用方案。方案解决了电力通信大容量光传输网络大跨距大带宽传输的难题,全面提升了网络的安全性、可管理性、可扩展性,为保障公司信息通信网络应用深化和完善提供了坚实基础。
In order to meet the needs of the data backbone network and the development of smart grid business in the 13th five - year plan period, it is necessary to build a communication transmission network with high speed, multi - service and large broadband. This paper describes the key technologies in the 100G OTN system, such as quadrature phase modulation, coherent reception, soft decision error coding and correction, etc.; analyses the feasibility application of 100 G OTN key technologies in large capacity and long distance optical transmission network. And then proposes its application scheme in large-capacity optical transmission electric power communication network. The scheme solves the problem of large span bandwidth transmission of large-capacity optical transmission electric power communication network, improves the security, manageability and scalability of the network, and provides a solid foundation for the deepening and improvement of the application of information ＆ telecommunication network.
