The relationships between impulse power and error bit of the traditional dispersion-compensated systems: pre: post-and hybrid-compensation in the presence of SPM, IXPM and IFWM were investigated.

Theintrachannel cross-phase modulation (IXPM) and intrachannel four-wave mixing (IFWM) in dispersion managed quasi-linear systems is researched, and the role of the timing jitter induced by IXPM and the amplitude jitter and the ghost pulse induced by IFWM change with distance and dispersion map strength are analyzed theoretically.

Self-phase modulation (SPM), intrachannel cross-phase modulation (IXPM) and intrachannel four-wave mixing (IFWM) in dispersion compensated high speed optical communication systems are researched, and the role of the symmetrical perturbation induced by SPM, timing jitter induced by IXPM and amplitude jitter and ghost pulse induced by IFWM are analyzed.
