Diseño y simulación de sistemas de comunicación óptica por el espacio libre usando múltiples transmisores/receptores mediante OptiSystem.

Abstract

Various communication technologies through wireless optical links can achieve data transmission speeds in the order of Gbps, making them effective solutions for areas of difficult access or where the implementation of physical fiber systems is very complex, such as country regions, airports or remote territories. This is how the FSO technology allows users to move without losing connectivity within the coverage area, is easy to install and manage and is free of spectrum licenses, which reduces costs. The security present in this technology within the transfer of information and the considerable immunity to interference and dispersion effects, are prerogatives to take into account. In this work an analysis of the previously mentioned technology is accomplished, and different scenarios and configurations are simulated using the OptiSystem. Within this study, the behavior of the system was evaluated through indicators such as the error bit rate (BER), eye diagram and Q factor (quality factor), which made it possible to verify the successful operation of the link.
