Abstract: This study involved a quantitative evaluation of the performance of dispersion and polarisation of light in a fibre optic link for broadband communication. The dispersion that occurs in the transmission of a signal over a 120 km separation at 100 Gbps was studied, and uniform chirped fibre Bragg grating dispersion compensation was adopted using three particular setups: predispersion compensation, Post-Dispersion Compensation, and Mixed dispersion compensation procedures. Optical fibre is a medium consisting of slender glass or plastic strands that enables high-speed data transmission across a wide frequency range, spanning up to 25 GHz, and this is achieved without signal amplification. However, as data rates and transmission distances escalate, challenges stemming from nonlinearities and dispersion intensify, impacting overall performance. This study is devoted to tackling these challenges through the deployment of Fibre Bragg Gratings (FBGs) in three distinct configurations: pre-dispersion compensation, Post-Dispersion Compensation, and Mixed dispersion compensation. Its principal objective is to correct dispersion in a 120 km transmission operating at 100 Gbps. The results obtained from each of the three compensation methods, employing the Optisystem simulation application software, were then analysed using key performance metrics such as Bit Error Rate (BER), Quality Factor (Q-Factor), and received power to identify the best compensation method, with the ultimate aim of significantly enhancing signal transmission performance. Postcompensation of UFBG exhibits the best performance, with the highest quality factor, the lowest BER, and the lowest power requirements among the three compensation techniques. Hence, UFBG Post-compensation is recommended to mitigate chromatic and polarization dispersions in fibre optic transmission systems. The findings of this work will provide valuable information for the design and manufacture of fibre optic transmission equipment for long-haul data communication systems.
