The invention relates to a distribution
network communication networking mode based on an EPON (
Ethernet Passive Optical Network) layering technology in distribution network
optical fiber communication networking and an application thereof, belonging to the technical field of distribution network intellectualization in the power industry. A communication convergence layer is formed between a backbone
communication layer local side node and a converting
station node, and comprises a communication convergence switch (or a regional
Ethernet switch); abundant
optical fiber cores subjected to uplink convergence from a converting
station to a local side backbone communication network are connected with a power distribution communication
core router of the local side node; the power distribution communication
core router is connected with a power distribution automatic main
station system; and a downlink passes through the converting station node, and enters a communication access layer by using an EPON layer. The problem of contradiction between different communication service applications and maintenance of a main
electric network and a distribution network is solved. Backbone communication
optical fiber core resources are fully utilized, the optical
transmission equipment resources of a communication network are not occupied, the reliability of a
network communication backbone layer of the distribution network is enhanced, independent networking is performed, convenience is brought to maintenance, and the distribution
network communication networking mode has the advantages of very high expandability and the like.
