Application Research of Shaanxi Electric Power City Conflux Communication System Based on Automatic Switched Optical Network

Based on the comprehensive analysis of characteristics and advantages of automatic switched optical network(ASON) technology,this paper systematically proposes the construction principle,protection mode,technology selection and networking scheme of Shaanxi electric power city conflux ASON communication network.Furthermore,the paper compares the performance of the ASON and traditional synchronous digital hierarchy(SDH) network from the safety and economy aspect.Finally,through fault testing, the capability of intelligent optical network in resisting multiple point failures is validated,and it is proved that the fault recovery techniques of the intelligent optical network can significantly improve the reliability of the electric power communication network.
