Paper Abstract
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.
