Stability analysis of dispersion-managed soliton propagation with reamplification, reshaping, and retiming all-optical regeneration

We analyze the propagation stability of dispersion-managed solitons in long-distance fiber optic links, as it is influenced by in-line control elements such as synchronous intensity modulators and filters. The soliton stability analysis permits us to optimize dispersion map design as well as the input optical pulse's energy and prechirp in the presence of periodic all-optical regeneration. Substantial agreement is obtained between the predictions of linear stability analysis and beam propagation simulations. Dispersion mapping and control are optimized for amplification, reshaping, and retiming regeneration of long-haul transmissions at a 40-Gbit/s channel rate. (C) 2002 Optical Society of America.
