Abstract
This paper aims to discuss the common obstacles detected during the maintenance of railway communication optical cables,and explore the methods to analyze and locate and deal with such obstacles.According to the situation of fiber core blocking,the obstacles of optical cables are divided into several types,such as complete blocking,partial blocking,and excessive fiber attenuation.The causes of optical cable obstacles are analyzed,and are divided into natural disasters,external forces,human factors,and cable defects.For different types of optical cable obstacles,corresponding handling methods are proposed,including the principles for dealing with faults and obstacles,the sequences for achieving emergent reconnection and recovery,and the methods for locating and dealing with cable fault points.This paper emphasizes the importance of day-to-day maintenance management of railway communication optical cable lines,to ensure the safe operation of railway communication equipment,so as to guarantee the safety of railway transportation.关键词
