Comparison of theory and experiment for dispersion-managed solitons in a recirculating fiber loop

Abstract

Abstract—We have developed a model that accurately predicts the dynamics of the signal pulses and the growth of amplified spon-taneous emission noise in a dispersion-managed soliton pulse train propagating in a recirculating fiber-loop experiment. Theoretically predicted dependencies of the amplitude and phase margins for the marks and the amplitude margin for the spaces as a function of distance are in remarkable agreement with the experiments. This model allows us to determine the key physical effects that limit the propagation distance in our experiments. Index Terms—Amplitude margin, amplified spontaneous emis-sion noise, dispersion-managed soliton (DMS), excess gain, filter, phase margin, pulse dynamics, timing jitter. I
