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Sa-gnac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。
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.
