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.
