使用干涉法对电力系统OPGW光缆PMD的测量

The test of power OPGW cable PMD using interferometer method

文章对偏振模色散对光通信系统的影响作了简要说明,详细介绍了干涉法测量偏振模色散的原理并分别说明了干涉法测量偏振模色散的两种方式。结合实际OPGW光缆线路,给出了测试结果,测试结果表明,该光缆线路偏振模色散性能良好。

The paper firstly gives brief illustration on how PMD influence the performance of the optical communication system and then introduce the principle of interferometer method. Two different analyses of interferometer method are also proposed. Combined with actual OPGW line, the paper gives the results of the test. The results of the test show that the OPGW line under test is good at PMD property.
