摘　　要：目前WDM网中较为常用的光复用段保护系统采用光纤冗余实现，或采用保护段换协议。本文中提出的一种新方案继承了光纤冗余方式的简单性，同时又避免了该方式需要冗余光纤的缺点。在此基础上，给出了这种保护器环在不同网络环境下的应用。其明显的优点是可以十分经济地对WDM网提供保护，实现网络的QoS以及安全性能。Optical Multiplex Section Protection systems in current transmission network are mostly realized in two ways, either physical optical fiber redundancy or protection switching protocol.The new solution of this bi-fibers Multiplex Section Protector not only has the realization simplicity of physical fiber redundancy, but also without its disadvantage of redundant fibers. And its applications in various networks＇ environment are introduced in this paper. The advantage of its realization and introduction can economically protect the transmission networks with good QoS and network security.
