Abstract

The ramifications of optical fiber vibrations on the calibration phase of slope-assisted fast distributed Brillouin optical time-domain analysis, is studied. It is theoretically and experimentally found that for not too severe vibrations the Brillouin gain spectrum, as determined by classical BOTDA, is only negligibly broadened, still enabling the correct estimation of its -3dB frequency points along the fiber.
