Fibers of telecom grade were studied to account for the Stimulated Brillouin scattering (SBS) spectrum. The observed spectrum is inhomogeneous and exhibits characteristic spectral hole burning under cw monochromatic laser excitation. This phenomenon was found to arise from waveguide interaction of the pump and Stokes signals and is the dominant contribution to broadening of the Brillouin spectrum in optical fiber.
