“…On the other hand, orthogonal polarization multiplexing has been utilized as a technique for XPM suppression which does not depend on dispersion management [14]. In [15], symmetrically collided transmission methodology has been also proposed by using both distributed Raman amplifier (DRA) and erbium-doped fiber amplifier (EDFA) for quasi-ideal symmetric power distribution. Recently, it has been proposed that XPM-induced impairments could be reduced via spectral inversion by employing a finite-dispersion fiber and standard dispersion compensating modules [16].…”

We propose a chirp cancellation method reducing nonlinear distortion in NZ-DSF based longhaul DWDM transmission systems in which SPM and XPM-induced chirps are canceling each other. The polarity and the amount of the XPM-induced chirp are controlled by varying the relative time shift between pulses on neighboring channels and the launching channel power. Simulation results indicate that the proposed method can provide an improved performance in terms of Q-factor in long-haul DWDM transmissions.
