摘　　要：在机器学习算法的基础上,提出一种自适应阈值法提取OTDR事件候选点。介绍了OTDR事件候选点的概念、自适应阈值设计思路和改进型OTDR光纤故障定位算法。实验证明,所提出的算法可以在实际OTDR事件点检测中取得更好的准确度和召回率。On the basis of machine learning algorithm, this paper proposes an adaptive threshold method ex- tract candidate points of OTDR events, and it introduces the concept of OTDR event candidate point, adaptive threshold design method and improved OTDR optical fiber fault location algorithm. Experimental results show that the proposed algorithm can achieve better accuracy and recall rate in actual OTDR event point detection.

关 键 词：光纤故障定位 OTDR事件候选点 自适应阈值
