Abstract

In this paper, we theoretically and experimentally investigate the impacts of Kerr effect and fiber dispersion on longrange Brillouin optical time-domain analysis (BOTDA) systems. The results show that the self-phase modulation (SPM, Kerr effect) can induce considerable continuum spectral broadening on a Gaussian pump pulse at a relative low power for both normal and anomalous dispersion fibers; with the cooperative effect of SPM and anomalous dispersion, the modulation instability can cause discrete spectral broadening on a square pump pulse at a relative high power. The detrimental effect of pump pulse spectral broadening could reduce the performance and sensing-range.
