基于长距离光传送网的光信噪比计算
Optical Signal Noise Ratio Calculation based on Long-distance Optical Transport Network
摘要
Abstract
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.关键词
