摘要 提出了一种适用于点对多点结构无源光接入网(PON)的网络整体可靠性定义,用于全面准确地量化衡量PON网络可靠性.定义中引入故障影响因子,可以量化衡量包含网络完全正常工作状态和不完全正常工作状态的PON网络整体可靠性.对树形、带保护树形和环形PON网络整体可靠性和网络建设成本进行量化分析比较,得出典型的光网络单元(ONU)集中分布和ONU分散分布情况下,无保护单级树形和主干保护树形PON网络分支器的最佳放置位置. To quantitatively and comprehensively evaluate the network reliability of the whole PON, a new passive optical network (PON) reliability model is proposed. It can indicate the failure's effect on the network or the different contributions of different nodes and links. Based on this model, the network reliability and cost of PONs in typical optical network unit (ONU) location situations with typical topologies are analyzed, the optimized location of splitter in one-splitter tree PON and trunk-protected tree PON is given.
