Description
Summary: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 fibres (DCF) and single mode fibres (SMF). Due to this arrangement and the use of low duty-cycle return-to-zero (RZ) pulses nonlinear interchannel effects are sufficiently mitigated resulting in almost no additional degradation compared to the single-channel case.
