Research on configuration of distribution and power supply communication network with the ethernet passive optical network technology

Aiming at the difficulty problems of pilot application of Ethernet Passive Optical Network(EPON)technology in internal experimental unit of distribution and power supply communication network,through analyzing each structure characteristic of distribution network and power supply net work,puts forward typical configuration network mode for distribution and power supply communica tion network and the problems need pay attention to apply.The research result shows that distribution communication network should use chain configuration network based on the distribution line,power supply communication network should use the subsidence mode of optical line terminal(OLT) configu ration network based on the margin capacity of trunk fiber optic cable and the number of tenement in residential section to calculate comprehensively.
