Abstract
In this paper, performance analysis of 64-channel DWDM is investigated using EDFA and an optimized reflectivity of the
cascaded fiber Bragg grating (CFBG) to minimize the presence of more side lobes. The progress of 5G technologies in the
telecommunication industry leads to more end-users and higher data traffic, which increases data rate consumption. This
introduces more fiber nonlinearities, consumption of high input power, and introducing more sidelobes, thereby degrading
DWDM system performance. This research benefit shows that the EDFA and FBG with optimized reflectivity achieve high
gain and reduce side lobes. The performance of the proposed experiment can be assessed by computing the quality factor
(Q-factor), Bit Error Rate (BER), and output signal-to-noise ratio (OSNR) of a DWDM system embedded with EDFA and
CFBG system. The proposed DWDM system is analyzed from comprehensive simulations to achieve high-quality data
transmission with low power consumption for long distances. The spectral analysis shows that the absence of side lobes
indicates the reduction of four-wave mixing and enhances the system performance. The proposed system performance
parameters are investigated and achieved enhanced performance with a better Q-factor of 21.1099, BER of 3.28 E-98, high
gain of 37.74 dB, and achieves proper spectral eye-opening.
