摘　　要：基于光纤测量原理并结合施工及运行维护经验,文章从光纤的衰耗曲线出发,分析总结了各种光纤故障反映在测量曲线上的特征,从而为判断光纤熔接的质量和故障定位提供了实用判据,这些方法在施工、验收和维护3个环节上保障了OPGW的安全运行。Based on optic fiber testing principle and combined with the experiences in OPGW construction and maintenance, the author summarizes the features of different kinds of optic fiber faults by analyzing the attenuation curves. This method is helpful to adjudge the quality of fiber fusion and position the faults so as to ensure the reliability of OPGW operation.
