Soliton transmission control in time and frequency domains

Soliton transmission control techniques in both the time and frequency domains designed to enable ultra-long-distance soliton transmission are described in detail. Soliton transmission control in the time domain, which can be realized by synchronous modulation, is a retiming technique which removes jitter and nonlinear interaction between adjacent solitons. In addition, a transfer function reduces noise and the noise power eventually converges to a low level for any transmission distance. Soliton transmission control in the frequency domain, which can be realized with a bandpass optical filter, stabilizes the soliton pulse. A million-kilometer transmission experiment confirms the usefulness of these techniques.<
