Experimental evidence of pseudo-periodical soliton propagation in dispersion-managed link

We present the first experimental evidence of pseudo-periodical soliton propagation in dispersion-managed link. It is shown that the prechirp is a key element for the control of nonlinearity as predicted by the theory. The aim of this study is to compare measured and predicted pulse evolution along a dispersion-managed link in the anomalous-dispersion regime using a recirculation loop with 100 km dispersion-compensated span of standard fiber. Simultaneous measurements of spectral width and chirp are performed for different values of prechirp.
