Abstract :
Effects of CPM and FWM phenomena are quantitatively evaluated in conjunction with NRZ and optical soliton transmission formats in DWDM systems. CPM leads to spectral broadening which may cause severe pulse distortion. While FWM may result in significant crosstalk among the optical channels. To improve system performance, understanding nonlinear optical effects in long-haul transmission systems is important. In this paper, we investigate both the Q-factor performance of CPM effects and the generated FWM power for a 32 channel DWDM transmission system using NRZ and optical soliton signals
