Abstract

The demand for higher capacities in fifth-generation networks and upcoming generations can be met with technology such as Wavelength Division Multiplexing (WDM). A study has been conducted to enhance the performance of a system comprising of sixteen light waves that carry high data rates of 40 Gbps for each data source associated with one of the wavelengths. The key focus of this study was to optimize the system parameters, including channel spacing, power levels, and dispersion compensation, to increase the signal-to-noise ratio and reduce signal degradation, which would be compatible with high data transfer speeds. The aim of this work is to improve the efficiency and performance of the proposed system. Using the simulation program OptiSystem, the proposed optical communications system based on 16 WDM channels for the 40 Gbps optical link was improved. Several parameters were adjusted to improve the performance of the proposed system. By carefully treating variables that can significantly affect system performance and striving to maximize the signal-to-noise ratio, minimize signal degradation, including dispersion compensation strategies, and optimize power levels. This work can determine the ideal configuration for the 16 WDM channels by evaluating and comparing the performance of different optimization strategies to obtain better results compared to previous work. The results show the extent of the impact of the optimization process on improving the system performance, which makes the proposed system suitable for communications systems in the next generations.
