Exemplary embodiments of the present invention relate to electronic dispersion compensation (EDC). The interaction between the frequency chirp and the fiber dispersion is newly analyzed. The linear and nonlinear properties of the chirp-dispersion are separately analyzed. A pre-compensating transmitter may consist of a phase interpolator (PI), a 2 tap data generator, a pulse widening CLK generator, a rising pattern detector, 4:1 Mux and an output driver. A post-compensating receiver may consist of linear equalizer for the rabbit ear compensation, nonlinear equalizer for tilting compensation, typical high frequency boosting equalizer (EQ) and limiting amp (LA).
