Measurement of stimulated-brillouin-scattering threshold for various types of fibers using brillouin optical-time-domain reflectometer

Abstract

We have investigated the stimulated Brillouin scattering (SBS) threshold of various types of fibers both theoretically and experimentally by utilizing Brillouin optical-time-domain reflectometer. The measured deviations of SBS threshold of less than +/-0.1 dB compared with the conventional method are demonstrated for standard single-mode fiber (SMF), large-effective-area dispersion-shifted fiber (LEAF), TrueWave/Reduced Slope fiber (TWF), and conventional dispersion-shifted fiber (DSF).
