自由空间光通信技术在电力系统的应用

Application of free space optical communication technology in electric power system

自由空间光通信是一种以大气为信道的宽带激光通信方式,具有高带宽、低成本、便于链路部署等特点,近年来在电信公网及各种专业网络得到一定的应用。文章回顾了自由空间光通信的发展历史,简要介绍其工作原理和技术特点,讨论了自由空间光通信技术的发展优势及难点,以及FSO技术的新进展,通过与几种常用的电力系统通信方式的比较,分析FSO技术在电力系统的应用前景。

Free space optical communication （FSO） is broadband laser telecommunication technology using the air as the channel. It has the advantages of wider bandwidth, lower cost and easier to deploy. It is used by both public and private carriers in recent years. In this paper, the author reviews the history of FSO, introduces its principle and characteristics, and discusses the development as well as the new improvement of FSO technology. The author also compares FSO with other means of telecommunication used in power grid and analyzes the prospects in the future.
