Optical fibre intrusion detection method based on Lefevre-loop and bidirectional polarisation optical time-domain reflectometer-C technique

Abstract

The authors validated a novel optical fibre intrusion sensor proposal based on Lefevre-loop and bidirectional polarisation optical time-domain reflectometer technique. Disturbances along 5 m fibre section inside 9 km perimeter were localised within 18 m resolution.
