Abstract

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.
