摘　　要：在全力推进"城市光网"建设的过程中,由于软件或硬件等原因造成的异常发光ONU故障严重影响了PON承载的业务质量,已经成为危害PON稳定运行的主要故障之一。但是异常发光ONU故障定位存在一定难度,给PON维护带来不小的压力,因此,尽快研究并提出一套行之有效的异常发光ONU检测方法,将为推动城市光网的发展产生重要的作用。本文通过对异常发光ONU的故障原因及检测机制进行深入分析和研究,提出了一种创新型故障检测思路。In the large scale MONET （metro optical network） construction, one of the critical issues may crash PON network stability is, software or hardware failures resulting in abnormal light emitting ONU, which impact the quality of services carried by PON severely. Therefore, it＇s important to find out an effective approach to detect the abnormal light emitting ONU and get rid of it. This is significant to the development of FTTH as well. This paper described a creative fault detection mechanism based on the thorough analysis to root causes of abnormal light emitting ONU.
