摘　　要：光通信系统传输速率的升级对光缆线路的传输性能提出了新的要求。针对电力特种光缆线路传输速率升级的需求,分析了衰减、色散、偏振模色散等传输特性对系统升级的影响并分别介绍了这3种光缆传输特性的测试方法。搭建了测试系统并对现役运行的光缆线路的传输特性进行了实际测量。提出的分析和测试方法可以作为系统升级时对光缆线路传输特性评测的参考。Upgrading of transmission communication system makes demand rate of optical of transmission performance of optical fiber cable. According to the demand of upgrading of transmission rate of special optical fiber cable for power communication, the influences of transmission characteristics such as attenuation, chromatic dispersion and polarization mode dispersion on upgrading of communication system are analyzed and the testing methods of the three transmission characteristics of optical fiber cable are l^resented respectively. A testing system is set up and actual measurement of the transmission characteristics of being operated optical fiber cable line is performed. The proposed analysis and testing method is available for reference in the evaluation of transmission characteristics of optical fiber cable line while the communication system is being upgraded.
