Abstract
The 2R Mamyshev regenerator (MR) [1] relies on the combined effects of self-phase modulation (SPM) and normal dispersion in a fiber to induce an S-shape transfer function (TF). At 160 Gbit/s (pulses of ∼1.5 ps), even with a very low dispersion fiber, the signal still experiences the effect of third-order dispersion β3 that degrades the shape of TF. To avoid this degradation, we demonstrate that an appropriate design of dispersion-managed fibers (DMFs) allows fully performing SPM-based 2R regeneration at 160 Gbit/s.
