摘　　要：采用区域分割还原与自适应噪声分析算法定位光纤非反射事件,并将该算法分析出来的事件形成事件分析库。实际光缆线路中的测试表明,该算法对不同统计特性的光纤具有自适应性,能检测到微小幅度的非反射事件,与传统的OTDR非反射事件检测算法相比,该算法提高了判断非反射事件的准确性。The paper presents a new method combining regional segmentation and adaptive noise analysis to locate fiber non-reflective events,and the analysis results form an event analysis database. Test results in actual optical lines show that the proposed algorithm is adaptive to optical fibers of different statistical performances and can detect non-reflective events of tiny amplitude, achieving higher accuracy of non-reflective event analysis compared with conventional OTDR non-reflective event detecting methods.
