Pe-OTN/OSU Based Multi-Service Bearing Scheme and Evolution Strategy for Electric Power Backbone Transmission Network

In order to solve the problem that the existing power backbone transmission network structure is difficult to meet the emerging service requirements of large capacity and multi-service carrying. This article proposed Pe-OTN/OSU based bearing scheme and phased evolution strategy for electric power backbone transmission network, which have high reliability, large capacity, intelligent management & control characteristics and can realize the comprehensive bearing of different services. The field test also fully verified the service bearing performance and reliability of Pe-OTN, which can provide a solid theoretical reference for the evolution of electric power communication network.
