Abstract

Periodic-group-delay (PGD) dispersion-compensation modules have recently been proposed as mechanisms to alleviate collision-induced timing shifts in dispersion-managed (DM) systems. We obtain frequency and timing shifts in quasilinear DM systems with PGDs and show that significant reductions are achieved when even a small fraction of the total dispersion is compensated by PGDs.
