An analytical approach to incorporate the cross-phase modulation (XPM) and self-phase modulation (SPM) to the calculation of system bit-error rate (BER) in a multispan intensity-modulation direct-detection (IM-DD) WDM system is presented in this paper. The effects of three important link parameters such as pump and probe power and span length, on the system performance have been investigated in terms...
An analytical approach to determine absolute power transfer due to cross-phase modulation (XPM) and self-phase modulation (SPM) from their spectral characteristics in a multispan intensity-modulation direct-detection (IM-DD) optical system is presented in this paper. Here, dependency of XPM and SPM power transfer on different link parameters like pump power, channel spacing, link length and, bitrate...
With the increasing demands on the capacity of wavelength division multiplexed (WDM) systems, nonlinear effects including inter-channel crosstalk become increasingly important. One of the most significant nonlinear effects in this context is cross-phase modulation (XPM) in optical fiber and accurate determination of this effect is an important issue in the design of WDM optical system. This paper...
