摘　　要：随着大容量、高速率光缆通信系统的广泛应用,通信网的稳定性对通信线路的日常维护管理工作提出了更高的要求。一旦发生光缆线路阻断,不但修复困难,阻断历时长,而且损失巨大,因此开发独立光缆自动监测系统成为光通信领域研究的重点。通过分析光缆自动监测系统的枝术特点,建立了光缆监测系统的硬件结构体系和软件结构体系。给出光缆自动监测原理及光缆监测三种监测方式在实践中的应用,实现光缆中断后迅速上报告警,及时自愈保护功能,使光纤传输线路管理维护进入自动化的时代。With extensive use of the large capacity high-speed fiber cable communication system,a higher demand of the stability of the communication network for maintenance work of the communication lines is proposed.In case of the occurrence of fiber cable blocking,it is not only difficult to repair,but also the time of blockade lasts for long and suffers a great loss,so the development of an automatic monitoring system becomes focus of the optical communication.By analyzing technical characteristics of the fiber cable automatic monitoring system,it establishes the hardware and software architectures of the system.It shows the principle of automatic monitoring and three kinds of modes for fiber cable monitoring applied in practice,realizes high-speed alarm reporting and timely self-healing protection when the fiber cable occurs breakdown,and makes management and maintenance of fiber transmission lines go into the automation age.
