Abstract

We demonstrate loss-insensitive operation of slope-Assisted Brillouin optical correlation-domain reflectometry by employing a special silica fiber with low bending loss. As fundamental characterization, we measure the coefficients of the power-change dependencies on strain and temperature to be 1.42 × 10-4 dB/μϵ and 3.28 × 10-3 dB/K, respectively. Subsequently, by comparing the distributed strain and temperature measurement results using a standard silica fiber and the special fiber, we show that this configuration offers highly stable loss-insensitive operation for practical use in the future.
