摘要

提出了一种基于环形awg波长路由器的wdm - pon分布式自保护方案。该新型波长路由器能够对上行链路和下行链路信号的工作光路和保护光路进行适当的路由。自动保护开关以分布式控制方式操作，因此实现了超短的0.7µs保护开关时间。保护所需的冗余纤维被最小化。

A novel distributed self-protection scheme for WDM-PON using a circulator-AWG based wavelength router

We propose a novel distributed self-protection scheme for WDM-PONs using circulator-AWG based wavelength router. The novel wavelength router enables proper routing of working and protection lightpaths of the uplink and downlink signals. Automatic protection switching is operated in a distributed control manner and thus ultra-short 0.7-µs protection switching time is achieved. Redundant fibers required for protection are minimized.
