Evaluation of nonlinear propagation effects on coherent optical transmission systems for various commercial optical fiber types

This paper presents the study of Gaussian Noise (GN) model based on power spectral density (PSD) of amplified spontaneous emission (GASE) noise and nonlinear interference (GNLI). GASE is the summation of erbium doped fiber amplifier (EDFA) noise in the optical link. GNLI appears for a number of channels in coherent optical transmission systems. We show the computed nonlinear effects on coherent uncompensated optical transmission systems (CUOTS) for different commercial optical fiber types (PSCF150, SSMF, SSMFULL) considering channel spacing, number of span, span length and number of channels respectively.
