摘　　要：总结分析了ROADM/OXC系统的几种保护恢复机制,现网测试了OMSP和WSON的协同工作能力,OCH 1+1、OMSP和WSON的协同工作能力,并依托现网测试数据,对ROADM网络中保护与恢复技术的工程应用进行了研究。研究表明OADM与OXC 2种设备支持混合组网,均可支持OMSP+WSON协同保护,但WSON网络对OCH 1+1与OMSP的组合支持程度有限。Several protection and recovery mechanisms of ROADM/OXC system are summarized and analyzed.The cooperative work-ing ability of OMSP and WSON,OCH 1+1,OMSP and WSON are tested in the current network.Based on the test data of the current network,the engineering application of protection and recovery technology in ROADM network is studied.The re-search shows that OADM and OXC support hybrid networking,and both support OMSP+WSON cooperative protection,but the WSON network has limited support for the combination of OCH 1+1 and OMSP.
