Abstract
A method for determining an optical signal-to-noise ratio penalty as a measure for a quality of an optical signal transmitted via an optical link between a source optical node and a destination optical node in an optical network, the method includes collecting information of the optical link; determining a configuration parameter Pof the optical link based on the information of the optical link; adjusting the configuration parameter Pto an adjusted configuration parameter P'according to linear impairments in the optical link; and determining the optical signal-to-noise ratio penalty based on a non-linear function of the adjusted configuration parameter P′, the non-linear function accounting for non-linear impairments in the optical link.
