Sun Zhifeng1, Liu Deming1, Liu Hairong1, et al. Distributed fiber vibration sensing network perimeter[J]. 2010,(4):23-24. DOI: 10.13756/j.gtxyj.2010.04.021.
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
