STRONG TIME JITTER REDUCTION USING SOLITONS IN 1 Z DISPERSION MANAGEDFIBER LINKS/

We propose and study a novel dispersion management method that permits the propagation of soliton pulses with a very low time jitter. The sc heme assumes a chromatic dispersion that on average decreases with a 1 /z law, where z is the propagation distance. The advantage of this met hod consists in the fact that at the end of the link the mean chromati c dispersion is very small and as a consequence the jitter can be deep ly reduced, while at the beginning of the link the chromatic dispersio n is high, hence the system can operate with a large input power that permits a good signal to noise ratio, The scheme is simply implemented by periodically compensating the chromatic dispersion with fiber piec es having different lengths.
