Abstract

Recently, a perturbative model of non-linear fiber propagation in uncompensated optical transmission systems has been proposed, called GN-model [1]. Here, an extended and more detailed version of the GN-model derivation [1] is reported, providing deeper insight into the model. Some straightforward generalizations of the model are also proposed.
