WDM of enhanced power solitons in strongly dispersion-managed systems

Much attention has been given to dispersion management in soliton transmission systems where both anomalous and normal dispersion fiber is used to construct the transmission line. Several advantages result from the combination of high local and low overall dispersion, most importantly a reduction in Gordon-Haus jitter, and also the means to achieve very small average dispersions with great accuracy. Recently, enhanced power solitons were identified as the stable propagating modes of strongly dispersion managed systems. In this paper, we demonstrate that strong dispersion management is also compatible with two-channel WDM soliton transmission over transoceanic distances. The effect of timing jitter due to collision-induced frequency shifts is kept down to acceptable levels, because the strong dispersion map increases the "effective" interaction length between pairs of solitons.
