长途干线光线路保护系统研究与应用
|
摘要
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,引起了学术界和工业界的高度重视。在一般光传输系统中,光网络高速率节点间互连是通过长途干线光缆实现,但长途干线光缆路由的安全条件差,在出现光缆阻断等情况下,网络单纯依靠SDH层面的环网保护,存在保护方式单一,安全性差,极端情况人工倒纤故障处理时效性差等问题。因此,必须对设计和建立光线路保护系统进行认真的研究。
作为一个系统保护的新领域,本文首先对光线路保护系统的需求进行分析,结合实际应用效果要求大胆提出了该系统设计实现的基本保护原理和保护实现方式,并系统设计和实施中存在并必须面对的主要问题进行分析提出解决方案。
针对上述设计实施主要问题,结合光线路保护系统设计目标与网络常见的应用类型,本文首先进一步对光线路保护系统中核心部件毫秒级光开关的实现原理、技术手段、试验分析进行了系统的实现论证;其次对基于光开关的光线路保护系统的整体设计框架、功能模块运用安排、系统软件实现、预期效果提出完整的构建、实施、测试方案;再次对基于该系统的光传输网络保护方案在中移动干线组网中的实际应用进行了方案设计介绍与实际参数分析,并对成功应用后整个系统的实际测试数据进行了采集和后评估工作。
文章最后对系统实施中存在问题和可能的未来改进方向提出相关设想。
The optical line protection system (OLP) is a long-distance optical transmission network production system, which has a very important practical value. This system is based on the optical switch of modern telecommunication millisecond level. As a new research field in the transmission of optical technology, the OLP system illustrates a good prospect of application, so it has commanded the high attention of both academic community and industrial community.
Compared with general optical network, the connection between high speeds of optical network depends on long-distance trunk line optical cables. Because the security for the routes of long-distance trunk line optical cable is so bad that when the optical fiber cables were interdicted, some problems would be brought if only depends on the protection of rig net at SDH level, such as single protection mode, poor security and poor prescription for dealing with some failures in extreme condition. Therefore, it requires seriously research on the design and establish of the protection system of optical circuit. Firstly, the essay analyses the protection system of optical.
This essay firstly analyses the OLP system, and clarifies the basic principle of protection and the realization for protection. And then the essay analyzes the issue existed on the design and realization. After analyzing the main issues on design and implementation of the system, this essay provides the direction of simple solution.
Aiming at the above main issues on the design and implementation of system, combined with the objective of the protection system of optical circuit and common network application type, this essay further discusses the principle of system realization on its centerpiece: optical switch on millisecond level; technology means and analysis of experiments. The practical application design composition functional module and its effect realization; This essay desirables the practical application and evaluation after test in trunk group of network in China Mobile Communication Corp on optical transmission network production system as well.
Finally, the essay provides the relative assume on the possible direction of the improvement according to the issues on system implementation in the future.
