Discussion on Communication Simulation Method of Backbone Optical Transmission Network

Under the background of the rapid development of smart grid, the provincial power communication network has formed a power communication private network architecture, which is mainly based on optical fiber communication technology, supplemented by microwave communication, power line carrier communication and satellite communication. With the continuous expansion of power communication network scale, the business types and information content carried by the communication system are growing rapidly, which leads to the problems of complex network structure and increasing operation and maintenance difficulty. Through the communication simulation of the three-level backbone optical transmission network, it is found that the backbone network has problems in nodes and links. It simplifies the network structure, reduces the pressure of operation and maintenance, and improves the reliability of power communication network.
