Periodic breathing of pulse width owing to strong dispersion management leads to significant overlap between adjacent pulses in long-distance fiber-optic transmissions. A striking result is that beyond a critical degree of overlap the interaction forces are no longer increased and are even reduced as the overlap is enhanced.
