Abstract:
A record long external-disturbance detection distance of 140 km without employing optical amplifiers in the fibre line is demonstrated by a phase-sensitive optical time-domain reflectometer (Φ-OTDR) using a fibre section with inscribed chirped fibre Bragg gratings (CFBGs). This solution provides simultaneous operation of Φ-OTDR with a standard single-mode fibre at a distance of up to 100 km and with a CFBG fibre section located from the fibre line input point by at least 140 km.
Keywords:
distributed sensor, fibre-optic sensor, phase-sensitive optical reflectometer, coherent reflectometer, fibre Bragg gratings, chirped fibre Bragg gratings.
