摘要
传输干线在整个传输网中占有重要的地位,广电长途干线网常因外力的阻力而中断,加强干线光纤路由的保护对广电光缆网信号的安全、稳定传输尤为重要。本文对光纤自动切换保护系统的组成和原理做了简要介绍,对保护系统的切换机制和特点做了简单描述,并介绍了光纤自动倒换系统在辽宁广电干线传输网中的实际应用。
Transmission backbone holds an important status in entire transmission network. Radio and television trunk network is often interrupted because of external resistance. It is very important to strengthen protection of the backbone routing for security and stable transmission on optical cable network. In this paper, composition and principle of i ber automatic protection switching system are briel y introduced. The paper describes switching mechanism and characteristics of the protection system. Also it introduces practical application of optical i ber automatic switching in Liaoning radio and TV trunk transmission network.
