Suppression of parabolic pulse-pair interaction using dispersion-managed fiber links with non-zero dispersion

We report on the suppression of the parabolic pulse-pair interaction by using the dispersion-managed optical fiber links with non-zero dispersion maps. The numerical results show that both the interaction and pulse splitting can be efficiently suppressed when the integrated dispersion is non-zero, and the pulse-pair can maintain their parabolic characteristics through the whole distance and turn to its original shape at the end of each map. Moreover, we numerically investigate the influence of the initial pulse width and chirp on the parabolic pulse pair propagation, which shows that the higher chirp is not conducive to pulse transmission.
