Abstract: Optical nonlinear effects of self-phase and cross-phase modulation and stimulated Brillouin scattering (SBS) determining the data transmission quality in fibreoptic communication lines are studied. The Stokes radiation power upon SBS is calculated taking into account the nonlinear broadening of the optical signal spectrum caused by self-phase modulation. The mechanism of signal distortion caused by the joint action of self-phase modulation and chromatic dispersion is considered. The main theoretical results are verified experimentally.
