Dispersion-managed solitons with in-line all-optical regeneration are shown
to be subject to amplitude and timing-jitter instabilities. We identify an
d discuss the different natures of these instabilities by means of a linear
stability analysis, which is in good agreement with the full numerical sol
utions of the governing equations. Stable pulse propagation can be achieved
through appropriate choices of dispersion map and pulse energy. (C) 2000 O
