【摘要】 基于波长路由的ＷＤＭ 全光网是下一代高速宽带光纤网络的首选技术。ＳＨＡＯＮＥＴ 是国内自主开发的第一个ＷＤＭ 全光试验网平台，它采用了一种新型保护结构的ＯＡＤＭ，具有很强的自愈功能。本文阐述了ＳＨＡＯＮＥＴ 中采用的快速自愈保护机制及其实现更多还原

【Abstract】 WDM all optical networks using wavelength routing represent the most promising solution for future high-capacity fiber networks. SHAONET, the first WDM all optical network testbed in China, is a metropolitan self-healing ring. A novel OADM having protection function is adopted. This paper presents the realization of fast self-healing mechanism using in SHAONET.更多还原
