摘要
针对光时域反射仪(OTDR)测量长距离光缆线路的动态范围受限问题,提出了一种基于双向OTDR测试的长距离光缆线路性能的测试方法,并构建了测试系统。该系统配置两台监测站,从长距离光缆线路两端分别测试,并将得到的测试曲线在监测中心进行拟合,拟合后的测试曲线能够反映该段光缆线路的性能状况。
As the dynamic range of the OTDR tests for long-range optical cable lines are limited,a bidirectional OTDR-based test method is presented and a test system established,in which two monitor stations are placed at the ends of a line under test.The resulted test curves are fitted at the monitor center and the fitted test curve reflects the performances of the line.
