Incremento de eficiencia espectral de una red pasiva óptica G-PON con modulaciones de intensidad y sistemas IMDD

Abstract

Abstract: Gigabit Passive Optical Networks (G-PON) are essential for Internet access and development of society. The demand for higher transmission speeds has increased due to technological advancement and user growth. This study explores improving spectral efficiency in conventional G-PON networks through PAM-4 and PAM-8 modulation. A simulation was used with Optisystem and Matlab, applying stress the network with an optical attenuator to evaluate its performance. The results indicate that the implementation of PAM-4 and PAM-8 is viable, reaching bit rates of 4.9 Gbps and 7.35 Gbps, respectively, with a target BER less than 0.001. This advance improves significantly the performance of G-PON networks, demonstrating the effectiveness of these modulation techniques to meet future data transmission needs. This work highlights the importance of optimizing telecommunications infrastructure to adapt to the demands of the digital age.
