Noise enhancement caused by polarization dependent loss (PDL) and the effect of dynamic gain equalizers (DGE) were discussed. It was shown that in cases where PDL induced signal to noise ratio (SNR) penalties were significant, the SNR degradation was dominated by the coupling of orthogonal noise into the polarization of the signal. Only a small number of DGEs were effective in mitigating PDL related degradation in performance.
