Extending the sensing range of Brillouin optical time-domain analysis up to 325 km combining four optical repeaters
2014
Proc. SPIE
A novel scheme is proposed to extend the sensing range of Brillouin optical time-domain analyzers (BOTDA). Specially-designed erbium doped fiber amplifier (EDFA) repeaters are located every 65km fiber along the sensing cable to achieve a total sensing length of 325km, corresponding to a 650km loop. At the end of the sensing fibre, we experimentally demonstrated a measurement repeatability of 2°C (2σ) using a three meters spatial resolution.
