Brillouin-gain profiles are measured for fused-silica core and GeO//2 -doped core fibres at wavelengths of 1286nm and 1550 nm. The intrinsic Brillouin linewidth is found to vary as the square of optical frequency, as predicted for bulk fused-silica. However, the experimentally evaluated Brillouin line-widths at both wavelengths are broader by a factor of 2. 5 than those predicted for the bulk glass.
