Influence of optical signal self-phase modulation on a channels quality of DWDM system

The problem of optical signal's self-phase modulation influence estimation on the optical channels quality in the system with a spectral channeling is considered. The simulation model of one DWDM system channel is constructed in the MatLab environment taking into account the amplified spontaneous emission noise of optical amplifiers as well as linear and nonlinear distortions in optical fibre. Comparison of the obtained results with the similar researches in this domain of science is performed.
