Abstract

Major challenge faced by today's
telecommunication is the increasing demand of bandwidth
and data rates. In order to expand the capacity of the optical
system, it has accelerated the development of high capacity
DWDM links. There are some barriers in DWDM related to
data rate and capacity. These barriers are linear and
nonlinear effects. Out of these barriers, linear effects such as
attenuation and dispersion can be easily compensated using
soliton and dispersion compensating fiber but there is an
accumulation of nonlinear effects. The nonlinear effects occur
in optical system are Self-Phase Modulation (SPM),
Stimulated Brillouin Scattering (SBS), Stimulated
Raman Scattering (SRS), Cross Phase Modulation
(XPM), And Four-Wave Mixing (FWM). Out of which
SBS and SPM is examined in single channel link
whereas SRS, XPM and FWM is introduced in multichannel link
In this paper optical link of different number of data channels
is studied using MDRZ modulation scheme at various input
power levels. Paper shows the simulated performance analysis
of the impact of Cross Phase Modulation and Four Wave
Mixing on DWDM optical network. The analysis is done on
the basis of Q-factor, Optical Spectrum and Eye Diagram.
Performance of link deteriorates as the input power and the
number of data channels increases.
