“…The chirp at the modulator can also affect the stability of pulse timing. Improper chirp at the modulator can make positive feedback, leading to the rise of the time shift of the pulse [12], [13]. Note that the stability analysis presented in Fig.…”

“…Taking advantage of the simple semitheoretical methods well developed for DM solitons, the system and input pulse parameters are optimized before applying full numerical modeling. The linear stability analysis based on the variational approach [22], [23], [27] has been successfully used to investigate DM soliton transmission [12], [13], [24]- [26]. The advantage of the method is a capability to predict both timing and energy fluctuations of the carrier pulse and the growth of the background noise in the zero time slots.…”

Abstract-Numerical optimization is performed of the 40-Gb/s dispersion-managed (DM) soliton transmission system with inline synchronous intensity modulation. Stability of DM soliton transmission results from a combined action of dispersion, nonlinearity, in-line filtering, and modulation through effective periodic bandwidth management of carrier pulses. Therefore, analysis of the multiparametric problem is typically required. A two-stage time-saving numerical optimization procedure is applied. At the first step, the regions of the stable carrier propagation are determined using theoretical models available for DM solitons, and system parameters are optimized. At the second stage, full numerical simulations are undertaken in order to verify the tolerance of optimal transmission regimes. An approach developed demonstrates feasibility of error-free transmission over 20 000 km in a transmission line composed of standard fiber and dispersion compensation fiber at 40 Gb/s. Index Terms-Dispersion-managed (DM) solitons, in-line filtering and modulation, optical regeneration, unlimited transmission over SMF at 40 Gb/s.

An exact analytical solution is derived for the variance of the timing jitter of a dispersion-managed soliton in the presence of synchronous amplitude modulators and filters. We show that, for a given position of these control elements, a total suppression of the timing jitter is possible, which will permit unlimited error free transmission distances of DM solitons. However, if only the modulator or the filter is used, the asymptotic behavior of the timing jitter shows a linear dependence with distance, which is in contrast with the cubic dependence in the uncontrolled case.
