摘要
电力系统通信网的网络生存能力和恢复能力极其重要。电力通信专网从原来以微波、载波通信为主要方式转向以光纤通信网为主要方式,因此必须采取必要的措施来保证光纤通信的传输可靠性。文章介绍了光纤线路保护系统(OLP)的结构及工作原理,以及OLP在苏州电力通信网中的应用,强调了OLP在自愈环网上应用的必要性,阐明了OLP所带来的经济效益。
The survivability and restoration of eleetrle power communication network are very important. In the past, the technologies that power communication network adopted are microwave and power line carrier, but now optical fiber occupies dominant position. In this paper, the author introduces the structure and the working principle of the Optic Line Protection （OLP） , and its application in Suzhou electric power communication network. The importance of OLP used in self-healing ring network is emphasized and the economic benefit that OLP brings is also clarified in the paper.
