摘要
介绍了波分复用全光网络的产生原因，以及全光网络的概念和优势。分析了全光网络的生存性策略，提出了基于两行单向和双向自愈环、四行双向自愈环的网络保护方式和网状网的恢复方式。分析了两种自愈方式在链路故障情况下的实现机理和优缺点。
The background of all-optical networks based on wavelength-division multiplexing is briefly analyzed in this paper, and the basic concepts and advantages of AON are introduced. Two-fiber unidirectional path-switched rings, four-fiber bidirectional self-healing rings and their schemes for network protection are mainly discussed. Compared to mesh networks, restoration in mesh networks is more important and efficient.
