电力架空光缆超长距离传输方案的探讨

Discussion and analysis on ultra-long haul transmission scheme of electric aerial optical cables

长距离光传输技术受到电力通信基建和运行管理部门及设备制造商的密切关注,成为近年来通信业的热点技术之一。以光纤复合架空地线(OPGW)为代表的长途电力架空光缆光通信传输得到了长足发展。文章分析比较了各类光纤的传输特性,并详细介绍了几种光纤放大方式和色散补偿,提出了7种利用OPGW光缆传输的方案,并做了简单地分析及比较。

The long haul transmission technology is come in for close attention by electric communication construction department, administrative department and equipment manufacturer. In recent years it becomes one hotspot technology in communication field. The long-haul electric aerial optical cable optical transmission represented by OPGW has got tremendous development. Different kinds of major transmission characteristics of optic fiber are compared and analyzed in the article, several optic fibers amplify ways and chromatic dispersion compensation are introduced in detail. Then put forward 7 kinds of schemes of utilizing OPGW optical transmission cable, and the analysis and comparison are given briefly.
