JITTER SUPPRESSION BY GUIDING FILTERS IN COMBINATION WITH DISPERSION MANAGEMENT

Enhancement of jitter suppression of a soliton by combination of fixed -frequency filters with periodic dispersion compensation is predicted in an analytical form by means of the Fokker-Planck equation for the s oliton's random walk. The result depends on the dispersion-compensatio n period but not on the ratio of the dispersions. Another result is pr esented that can help one to understand jitter suppression by dispersi on compensation without filters, which was observed in recent experime nts.
