摘　　要：提出并实验验证了一种利用自主研制的OTDR来有效定位PON的支路断点或异常损耗事件的方法,讨论了在PON的测量中OTDR面临的新问题和新要求。This paper introduces a method of locating fault events such as breaking and abnormal attenuation in each branch of PON. The method is verified to be effective by the experiment using an OTDR that is developed in the lab. This paper also summarizes some new challenges and requirements OTDR is faced with in the measurement of PON structure.
