Abstract
Transmission of ultrahigh data rates through fiber optics networks (FONs) over long transmission distances in an intensity‐dependent refractive index medium suffers from nonlinear self‐steepening (NSS) and stimulated Raman scattering (SRS). In this paper, a FON model is proposed to compensate NSS and SRS impairments, using a theoretical model and its verification through simulation for different set of parameters. The proposed FON is designed to support 8, 16, and 32 channels with dual polarization quadrature phase shift keying modulation format. The analysis is performed for a range of values for the transmission medium including nonlinear effective area, nonlinear refractive index, and nonlinear dispersion. Moreover, the performance of the proposed model is evaluated in terms of launch power, polarization variations, received power, and length of transmission fiber. The overall work is analyzed for transmission distances up to 1200 km for performance metric of bit error rate, eye diagram, and received symbols constellations diagram.
