      方法检测原理存在的问题
      人工拽拉溯源排查从能够识别光缆的地方(如标牌和出厂码标字等)开始逐一人工拽拉光缆,通过光缆的抽动辨识。1、需投入大量人力,时间较长;2、较多光缆绑扎固定在一起,无法分离的地方不适用;3、无法抽动的地方不适用;4、识别效率低,个别地方无法进行。
      光纤识别仪查找在光纤端头处连接光源,将光纤识别仪卡在光纤上识别。1、需打开光缆接头盒或末端;2、操作复杂、费时,有损坏光纤的风险;3、不能全程识别,识别效率低。
      红光源查找在光纤端头处连接红光源,目测光纤红光通过情况。1、需打开光缆接头盒或末端;2、操作复杂、费时,有损坏光纤的风险;3、识别距离短,不能全程,效率低。
      OTDR+光缆弯曲(上速冻液)通过弯曲光缆或光纤产生大的弯曲损耗,产生损耗台阶。1、弯曲光缆对光缆有损害;2、用牙签或速冻液,需打开接头;3、操作过程复杂、费时,存在损坏光纤的风险;4、对弯曲不敏感光纤(如:G657)不适用;5、无法弯曲的光纤识别效率低。
      射频探测法[6]采用电磁场原理,根据场强的大小,判断光缆位置。可以判断光缆路由,但无法区分同路由光缆。
      光缆敲缆普查仪通过光干涉原理,敲击点振动强,非敲击点振动弱,形成敲击区域内光强强弱分布的现象[7]1、ODF反复互换接口,重复劳动多;2、现场需把光缆分开敲击,工作量大;3、每次只能作业1个位置;4、效率低。

      工具优势劣势使用场景
      缆线识别仪普查效率高不能跨接头盒,多次连接逐人井和逐杆精细化普查
      光缆敲缆普查仪能跨接头盒,1次连接普查效率低跨多个人井和多个电杆大段落粗查[8]
