Collision-induced timing jitter is theoretically and numerically studied for two-channel wavelength-division-multiplexed optical soliton transmission systems with both weak and strong (practical) dispersion management. For a weakly managed case the timing jitter induced by the residual frequency shift strongly depends on bit rate per channel owing to the correlation in the relative time shift in neighboring pulses. We also discuss the effect of dispersion management for reducing the timing jitter. For a strongly managed case the timing jitter is mainly induced either by the accumulated position shift or by an incomplete-collision-induced residual frequency shift. It becomes significant for nearly zero path-averaged dispersion. We optimize the path-averaged dispersion of the line composed of 1.3-µm zero-dispersion single-mode fiber and its reversed dispersion fiber by minimizing the jitter caused by both collision and amplifier noise.
