| Abstract: | This paper first studies the propagation of nonlinear phase noise(NPN) through transfer function defined in under effect of dispersion and Kerr nonlinearity respectively in the frequency domain.Based on the theory and adopted local-error method Split-Step Fourier Method(LEM-SSFM),it analyzes NPN and the system performance by SNR from the transmission distance,launch power and number of amplifier under both dispersion and nonlinearity effects in a multi-channel multispan wavelength-division multiplexed(WDM) system. |
