DYNAMICS OF SOLITONS IN FILTERED DISPERSION-MANAGED SYSTEMS

We present measurements of the temporal evolution of soliton propagati on in a dispersion managed fiber transmission line containing one opti cal bandpass filter in each map period. The pulses expand and compress in time due to the local dispersion with two minima per map cycle, on e in the middle of the anomalous and the other in the middle of the no rmal section of the fiber map. The pulses are nearly transform limited at the minima with Gaussian-like spectra. A new type of solution beha vior is indicated by the fact that the dynamics, measured bit-error ra te (BER), excess gain, and pulse stability do not vary with path-avera ged dispersion from 0.02 to 0.08 ps/mm/km.
