The necessity for environmental protection has led to the development of
different sensors for monitoring fuel pipelines to avoid explosion, leakage,
and corrosion. Distributed optical fiber sensors-based Brillouin scattering have
become progressively common because of their novel feature of
simultaneously determining temperature, vibration, and strain. The stimulated
Brillouin scattering (SBS) threshold power, sensing distance, single-mode
fiber cable length, and sensing accuracy are serious parameters to the
implementation of Brillouin optical time-domain reflectometry (BOTDR)
sensor. In this study, remote sensing of multi-BOTDR fiber optic sensors for
fuel pipeline monitoring is designed and presented. The results of
simulations and theoretical explainations on suppressing fiber optic
nonlinearity are analyzed. Results show that an SBS suppression via 16 dB is
required to attain the maximum multi-remote sensing distance of up to 20 km
for each network and a perfect frequency shift of 11 GHz. An open eye
pattern corresponds to minimal signal distortion with a high Q-factor of 22
for the developed sensor. The highest sensing accuracy of 0.3318 %/K
indicating power change (%) is observed from 290–300 K at 193.1 THz
operating frequency.
