Optical 2R regeneration of 10 Gbps signal using cascaded fiber four wave mixing

摘要

A fiber-FWM based all-optical 2R regeneration technique with near-ideal (step-like) transfer function is proposed. By setting proper modulation index and wavelength relations in a two-stage cascaded approach, we succeeded in near spectral-spread free 2R regeneration, with demonstration of improved performance for 10 Gbps NRZ PRBS data transmission.
