Propagation properties of strongly dispersion-managed soliton trains

We analyze the intra-channel interactions of strongly dispersion-managed soliton trains. We systematically study the transmission system in terms of a coalescence distance. The impact of third-order dispersion and the positions of the amplifiers are evaluated. We also study the effect produced on the interaction patterns by the modifications in the pulse timings and relative amplitudes. Based on the results obtained, we propose a channel encoding scheme which gives a noiseless capacity very close to that of the conventional binary soliton signaling and, yet, provides a significant improvement in the interaction limitations.
