Abstract

A single frequency Brillouin fiber laser used as a local oscillator for Brillouin optical time domain reflectometry (BOTDR) is designed and developed without using expensive instruments or complicated system. A BOTDR with this reference Brillouin laser for distributed measurement over 53km sensing fiber has been experimentally demonstrated. Experimental results show that the system can accurately measure the Brillouin scattering spectrum distribution with a much lower frequency bandwidth detector.
