Summary :

We study effects of preamplifier nonlinearity on polarization mode dispersion (PMD) equalization performance of feed-forward equalizer (FFE) electronic dispersion compensation (EDC) IC. We have shown that a nonlinear limiting amplifier can be used as a preamplifier for FFE EDC IC for a 6-dB dynamic range.
