摘要
随着国家电网的快速发展,大型电力通信网向光传送网(OTN)组网快速演进以支撑电网管理、运维中的大量数据通信需求。大型的OTN组网具有长距离光通信的特点,光信噪比(OSNR)是衡量网络质量的重要参数,为保证高效传输,系统OSNR计算具有重要的研究与应用意义。文章针对长距离OTN电力通信网,分析了网络拓扑的特点,提出了基于该网络特点的OSNR计算方法,并分析了该计算方法的特点、意义及推广价值。
With the rapid development of national power grid,large-scale electric power communication network is moving into Optical Transport Network(OTN)to satisfy the management,operation and maintenance in a large number of power grid data communication.Long-distance optical communication is the characteristic of large-scale OTN,and Optical Signal Noise Ratio(OSNR)is an important parameter to measure the quality of the network.In order to ensure the efficient transmission,the calculation of OSNR is necessary to the network.This paper focuses on long-distance OTN power communication network and analyzes the characteristics of topology.The new OSNR calculation method is proposed based on the topology structure,and it’s significance and promotion value are also investigated in detail.
