H. Lee, T. Ma, Y. Mizuno, and K. Nakamura, "Bending-loss-independent operation of slope-assisted Brillouin optical correlation-domain reflectometry," Sci. Rep., vol. 8, 7844 (2018).
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.
