Abstract :
In this paper, we present a theoretical analysis of the noise resulting from cross-phase modulation in an optical WDM transmission system. Analytical approach has been used to evaluate the bit error rate (BER) performance limitation of a WDM transmission system imposed by crosstalk due to cross-phase modulation and the influence of changing channel spacing for various fiber types on the (BER) and the cross-phase modulation noise. Mathematical expressions are derived and solved that describe this fiber nonlinearity impairment in a multi-channel optical fiber network with highlighting the mitigation techniques. Numerical results demonstrate the validity of the analysis and theoretical expressions to have an insight about this nonlinear effect under investigation.
