摘　　要：介绍了一种新型智能光路保护系统,其实现了对光缆线路实时监测与远程控制管理,能及时发现光缆故障并快速倒换,保证光通信系统的透明无阻断通信。该系统采用1+1保护方案,通过实时采集工作光纤中的光功率来监测光缆工作状态,利用光开关在工作光纤和备用光纤间倒换,有效保证光路的畅通。光开关是该系统实现光路自动倒换的关键器件,详细阐述了光开关在该系统中应用的工作原理及方案。A new intelligent optical switching protection system is presented. It realizes the real time supervising and remote control management on the fiber optic cable link, and can timely find the fault of fiber optic cable and rapidly realize switching, so as to guarantee the transparent and uninterrupted operation of optical communication system. The system obeys the principle of the 1＋1 protection method, though real time acquisition of the optical power in the working fibers supervises the operation status of the fiber optic cable, and utilizing the switching of the optical switch between working fiber and standby fiber ensures the optical path uninterrupted. Optical switch is a key device for a system to realize automatic switching of the optical path, so the application principles and schemes of optical switch in this system are described in detail.
