A distributed optical fiber sensor system for intrusion detection and location based on the phase-sensitive OTDR with remote pump EDFA

Yage Zhan et al.

Summary: A distributed optical fiber sensor system for multi-intrusion monitoring over a 25 km distance has been proposed in this paper. By combining various technologies including SOA modulation, the system achieved a SNR of 9.5dB for intrusion detection at the remote tail end of the 25km distance.

Summary: This study introduces a multipath distributed acoustic sensing (MP-DAS) system based on Phi-OTDR and FDM technique, enabling simultaneous monitoring of multipath vibration with flexible parameters adjustment. A dual path Phi-OTDR system with 1 km and 22 km measurement distance is demonstrated in the experiment, providing high-resolution vibration sensing capabilities.
