摘要
为提升无源光网络系统的运行可靠性,文章根据无源接入网的结构特点,从设备器件可靠性、网络结构以及保护结构的可靠性对无源光网络可靠性进行建模,提出了无源光网络可靠性分析算法,分析了影响系统可靠性的关键因素,总结了提高系统可靠性的方法。在此基础上,设计了中低压配电系统中通信系统的可靠性架构。通过无源光网络可靠性分析,可指导设备器件的选购、网络组织结构设计以及业务管理,切实提高无源光网络的实用性,降低成本,提高系统的稳定性与可用性。
In order to improve the operation reliability of PON（Passive Optical Network, PON）, according to the structure of the passive optical network, the reliability of PON is studied and modeled from device reliability, network structure and protected x PON. Based on the model, the key factors of reliability are investigated and the methods of improving reliability are summed. The reliability framework of communication system for middle and low voltage power distribution system is designed. Our research can be used for choosing devices, net-structure designing and business management, for the aim of reducing cost and improving reliability and usability.
