摘　　要：有效的故障管理需要依靠从网络中收集到的信息来实现,在透明光网络中,这些信息通过监控设备来传递。可通过分析光设备和监控设备的特性,利用编码的方法对透明光网络(设置了监控器)进行故障定位。文章采用的算法既考虑了不存在漏/误告警的理想情况,也考虑了存在漏/误告警的非理想情况,从而提高了故障定位的准确性。The implementation of efficient failure management relies on the information collected from the network. In transparent optical networks, such information is delivered by the monitoring equipment. Failures in such networks can be located by encoding on the basis of analyzing the performances of the optical and monitoring devices. The failure location algorithm used in this paper can cope with both the ideal scenarios （no false and/or lost alarms）, and nonideal scenarios （having false and/or lost alarms）, thus improving the accuracy of failure location.
