Lightpathes of WDM ring using share protect and wavelength reuse will be easy to misconnect when multi-fiber-fault or node-fault happen.

采用长重用和共享保护复用(WDM)环网在多点故障或节点失效时产生错连。

It shows that this kind of device can be tuned hundreds of nanometers.It can demultiplex any channel in all-wave fiber WDM in the future.

析表明，它调谐量可以百纳米，有望在来全光纤WDM中对所有信道进行解复用。
