Study of the Impact of optical nonlinear interference on elastic optical networks

Abstract

In the BTP, an innovative lightpath OSNR estimation model has been developed which considers the Ampli ed Spontaneous Emission (ASE) noise and Nonlinear Interference (NLI) sue to Inter-channel Stimulated Raman Scattering (ISRS) while predicting the OSNR of a network lightpath. Further, this model has been used to report the bene ts of operating at reduced Link Margin(LM) in various diverse networks across the C+L band optical spectrum. K
