【摘要】 提出了一种新型光缆实时监测系统的设计方案 .系统通过光耦合器对每根光纤的光信号取样 ,然后对其光功率进行测试 ,将测试结果送到中央控制器进行计算、分析和处理 ,显示出测量数据 ,并根据处理结果控制光开关进行切换 ,再通过波分复用器 ( WDM)使故障光纤接入光时域反射计 ( OTDR)进行上下测试 .更多还原

【Abstract】 The solution of the real time supervisory system for optical fiber cable is proposed. This system is made up of sampling the optical signal by optical couple, measuring its optical power, calculating, analyzing and dealing with the results transmitted to the central controller, and showing the calculating data. The central controller can control the turn of optical switch by the analyzing results, and connect OTDR with the troubling optical fiber to test up and down by WDM.更多还原
