This paper analyzes value of the joint loss of optical fiber measured by an OTDR.

对用otdr测试光纤接头损耗值进行了分析。

In project the important function of OTDR is searching the break point and locating it.

OTDR在工程上的重大用处是能够方便地找出光纤的断点，并进行故障定位。

There may be unreal peaks on backscattering signal curve in the measurement of optical fiber links by OTDR.

用OTDR测试光纤线路时，其背向瑞利散射信号曲线上常出现幻峰。

The result shows that real splice loss is determined by the average value measured by OTDR in 2 directions .

结果表明，真正的接头损耗应由OTDR双向测试的平均值决定。

The proposed system adopts the design of the light power spring OTDR test, which makes system monitoring real-time.

系统采用光功率触发ot DR测试的设计方案，实现真正意义上的实时监测。
