Abstract :
We study the effect of polarization dependent loss (PDL) on the signal to noise ratio of optical communications systems. We discuss the value of dynamic gain equalization in this context and show that in most cases of interest, the penalties that are induced by PDL are caused by the coupling of noise that is emitted into a state of polarization that is orthogonal to the signal.
