摘要: 利用对光纤接入网保护的分析, 探讨了光纤接入网环形自愈网的结构; 通过分析双纤单向通道倒换环和双向通道倒换环的工作原理, 证明了双纤通道倒换环的倒换次数只与节点数有关, 而与信息传输方向无关.根据分析结果, 探讨了在光纤接入网中自愈环的应用.

关键词: 光纤通信网, 接入网, 自愈环, 通道保护环, 自动倒换次数

Abstract: Based on the introduction of the general concept ofthe protection for optical access networks, the architecture of self-healing ring is discussed. Analysis of the features of 2 fiber bi-directional path switching ring are made. The calculating result shows that the number of switching time of 2 fiber Path switching ring is related to the number of nodes and independent of the transmitting direction of the traffic signal. According to the resultabove, issues on the application of the Self-Healing Ring for optical access networks are briefly discussed.

Key words: optical fiber communication networks, access networks, self-healing ring, path protection, number of automatic switching times
