Abstract
The impact of a compound fibre exhibiting discontinuous Brillouin shifts on stimulated Brillouin scattering (SBS) in a 2.5 Gbit/s CPFSK transmission system consisting of an optical booster amplifier and a nondispersion shifted transmission fibre is described. The power penalty due to SBS is almost completely eliminated by the novel compound fibre which is constructed with four short lengths of nondispersion shifted fibre joined end to end.
