Abstract

We describe coherent self-heterodyne detection Brillouin OTDR enhanced with an optical frequency shifter using sideband light generated by a 14-GHz bandwidth phase-modulator and measure the distributed tensile strain in 30-km dispersion-shifted optical fiber with 100-m spatial resolution.
