【摘要】 随着数据及3G业务的快速发展,高速数字交换技术和密集波分复用的应用越来越广泛,这使得越来越多的信息业务集中到较少的节点和线路上。如何更好的保障传输线路的安全性,在当前光通信网络的建设中显得尤为重要。目前,在众多光网络保护方式中,OLP具备切换时间短、响应速度快、掉电后光路状态保持、对传输数据透明等优点,在高速率光传输网络中获得了广泛的应用。光线路保护系统是一种基于现代通信毫秒级光开关为基础的具有重要实践意义的长距离光传输网络保护系统。作为光传输技术的一个新的研究领域,具有十分广阔的应用前景,引起了工T行业和学术界的高度重视。本文结合内蒙古联通干线传输骨干业务实际的应用要求,对光线路保护系统进行了深入研究和分析,设计了适用于实际系统的保护实现方案,实现了光线路保护技术在传输网络中的应用。本文工作内容如下:1、进一步对光线路保护系统的实现原理、技术手段、试验分析进行了深入、系统的研究和分析;2根据实际需求,对光线路保护系统进行了整体框架的设计,根据系统预期效果提出完整的构建方案;3、将光线路保护方案应用在内蒙古联通干线传输骨干业务组网中,达到了很好的效果。

【Abstract】 With the development of the data and 3G service, the application of the high rate digital transmission and dense wavelength division multiplexing is more and more broad. so many information services need to concentrated the information to the less node or the line. How to better protect the safety of transmission lines is very important to the current building of optical communication networks. Currently, in many optical network protection mode, OLP gains broad application in rates high-speed brightness transmission net, with some characteristics as short switching time, a fast response, optics maintaining after power down, the transmission of data transparency and and so on, and it have attracted the academic and IT industry attention.According to the application requirements of the Inner Mongolia Unicom trunk transmission backbone business, This essay take a thorough study and analysis to optical line protection system, and designed a program for the actual system, achieved application.of the optical line protection technology in the transmission network.This work is as follows:1. This essay take a thorough study and analysis to optical line protection system principles, techniques, and test analysis;2. This paper made the overall design framework for the optical line protection system, and according to the effect building a full system program;3. This paper appled the optical line protection schemes in Inner Mongolia Unicom trunk transmission backbone network in the business, and achieving good results.
