Interactions between dispersion managed solitons in optical-time-division-multiplexed system

Nonlinear interactions between neighboring pulses in optical-time-division-multiplexed (OTDM) systems may cause a timing jitter of the signal pulse, which results in a limitation of the transmission distance and bit-rate. We show that alternating the phases or amplitudes of pulses in the time sequence is effective for reducing the interactions between dispersion managed solitons as in the case of ideal solitons, but only for a relatively weak dispersion management.
