Evaluation of Nonlinear Interference Effects in a Dispersion Managed
(DM) Optical Fiber: Performance and Transmission Analysis of 16QAM
Modulation using Split Step Fourier Method
Abstract
This paper investigates the impact on the optical
signal-to-noise ratio (OSNR) of the residual per span (RDPS) in a N ×
100km dispersion managed system with zero total accumulated dispersion
from input to output using split step Fourier method (SSFM) -Monte Carlo
simulation.
This paper shows that the nonlinear interference NLI does in-fact impact
the performance yielding different best working power depending on the
value of Nx100 km span and the type of dispersion managed link. The
paper shows that dispersion uncompensated optical links are preferable
to dispersion managed fibers in equalizing NLI effects in long haul
optical links.
