An analytic approach to calculation of Q-factor degradation due to the fibre nonlinearities in a wavelength-division multiplexing system is presented, as well as their interplay with dispersion and ASE noise accumulation. The derived expressions are applicable to any channel and any fibre type. The derivation of analytic solutions facilitates in studying and understanding complex optical communication systems in a way that is not possible using numerical simulations. The results suggested that the optimum selection of the power per channel could strongly depend on several system parameters. The model we have developed can be used in designing advanced WDM systems with a large number of channels spanning many amplification bands.
