摘　　要：分析了宽带无源光网络(BPON)拓扑结构的特点和分类,提出了用″系统存活率″对无源光网络进行生存性分析的概念和方法.据此,研究了各种类型BPON可存活网络的备份保护拓扑结构,特别提出了几种最具开发和应用价值的部分双重配置或共享型的BPON自愈树和自愈环,以解决BPON大规模推广应用时如何能够作到低成本、高系统存活率的难题.The paper analyses the characteristics and classify of BPON's topological structures, and presents the concepts and methods of The Rate of System Survival ( Consumer Livability ) used for survivability analyses of BPON. The paper hereby researches on all sorts of BPON survivable networks and their protection switching methods and structures, and introduces some valuable BPON survivable networks to involve several partial duplex configuration or sharable self-healing tree and self-healing ring.
