Análisis de propagación de las comunicaciones ópticas subacuáticas.

Abstract

This article presents a study of light propagation in aquatic environments. The main objective was to research and understand the phenomena that cause propagation losses in the transmission of light in liquid media, specifically water under different conditions. To study the behavior of these waves in a liquid medium, a simulation was carried out using a Corning SMF-28 singlemode optical fiber with a water transition using the FIMMWAVE software and performing an analysis through polynomail regression, relating the variation of the wavelength as a function of the permittivity of the water, with which an equation with a polynomial behavior of order 11 was obtained. The wavelengths analyzed spanned a range of 0.18 to 1.13 μm, considering drinking water as the transition medium. In the analysis of results, FIMMWAVE's WG Scanner tool was used to analyze the propagation modes in the optical fiber, observing an exponential behavior beyond a certain wavelength value. This study seeks to advance the knowledge of underwater communications and provide relevant information for the design and optimization of optical transmission systems in aquatic environments. Understanding light propagation in this context is critical to improving the quality and efficiency of submarine communications.
