摘要
文章介绍了一种基于混合时分/波分复用技术的分布式光纤振动传感网络周界。系统基于光纤干涉传感技术，采用Sagnac干涉仪作周边警戒单元，结合网络通信中的混合时分/波分复用技术，实现了120个用户单元的联合周边警戒，并可扩容到256户。
Abstract
A hybrid TDM/WDM technology-based distributed fiber vibration sensing network perimeter is introduced in this paper. On the basis of fiber interference sensing technology, using a fiber Sagnac interferometer as a perimeter alerting unit and combining with the hybrid TDM/WDM technology for network communications, united perimeter alerting for 120 user units is achieved, which can be expanded to 256 users.
