Abstract

We propose and demonstrate a high-performance and long-range Brillouin optical time-domain analysis (BOTDA) based on time-division multiplexing measurement, where a probe pulse and a pump pulse are used to perform the measurement on a selected sensing section, and the measurement of the entire sensing fiber is realized by combining the series measurements over different sections through changing the delay time between the two pulses. In experiment, a 100 km sensing fiber is divided into 11 sections based on the gain-controlled principle, and spatial resolutions of 0:6 m and 2 m are obtained at the end of 75 km and 100 km, respectively.
