Abstract

Analysis of stimulated Brillouin scattering (SBS) in an AM-CATV link is presented. In externally modulated lightwave AM-CATV systems the stimulated Brillouin scattering threshold power (around 7 dBm) can be considerably increased by broadband phase modulation of the optical carrier. Influence of the phase modulation on nonlinear distortion caused by self phase modulation and dispersion of the transmission fiber was evaluated. Additional phase modulation, synchronized with amplitude modulation, was proposed which, in some special cases, leads to CSO distortion decreasing and increasing the transmission distance
