摘　　要：传统的光缆基于光功率进行监测,虽然可以监测光纤的总损耗,但不能反映光纤的损耗情况,也不能发现光缆出故障的位置。为此,提出了一种基于多通路的光缆监控系统,该系统主要由OTDR和光开关组成,OTDR能测试光纤的损耗情况,通过分析OTDR曲线可以准确地找出光纤故障的类型与距离,同时采用多路光开关来切换不同的联络,以降低成本。本系统在某管道工程中应用,采用了2台OTDR和16路光开关,节省投资约2万元。Traditional FOC detection bases on the optical power, which, although, can monitor the total fiber loss,but don＇t react the loss of the fiber performance,and also cannot find the location of the cable out of order. Presenting a FOC monitoring system based on multiple channels,it consists of OTDR and optical switch,OTDR can test the performance of fiber loss well,and with the analysis of OTDR curve,the optical fiber fault type and distance can be accurately found out. At the same time, using the multi- channel optical switch to switch different contact to reduce costs. This system obtained the good application in engineering, adopts 2 sets of OTDR and 16 road optical switches, save investment of about 20 000 Yuan.
