无源光网络技术在配、用电通信网中的组网研究

针对无源光网(Ethernet Passive Optical Network, EPON)技术在全国配、用电通信网中的试点应用的难点问题,通过分析配、用电网各自的结构特点,根据EPON技术在配、用电通信网全国试点的应用经验,提出配、用电通信网目前典型的组网模式及应用中需要注意的问题,为EPON技术在配、用电通信网建设中大规模应用奠定基础。研究结果表明:配电通信网应根据配电线路采用链型组网,用电通信网需要根据主干光纤富裕度和小区户数综合考虑是否采用光线路终端(Optical Line Terminal, OLT)下沉模式进行组网。

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 communicationnetwork,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 distributioncommunication network should use chain configuration network based on the distribution line,powersupply 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 inresidential section to calculate comprehensively.
