Abstract

We experimentally investigate a dispersion-managed four-channel 2R regenerator that relies on self-phase modulation-induced spectral broadening and offset filtering at four shifted wavelengths. The device consists of several alternating sections of dispersion-compensating fibers and single-mode fibers. Due to this arrangement and the use of low duty-cycle return-to-zero pulses, nonlinear interchannel effects are sufficiently mitigated resulting in almost no additional degradation compared to the single-channel case.
