Short-Reach Multimode Fiber Optic Network Upgrade for High Bit Rates

This project addresses the critical need to increase bit rates in communication networks, moving from 1Gbps to 100Gbps, driven by the demand for intensive data services. The main obstacle in existing optical networks is the high modal dispersion inherent in Multimode Fiber (MMF), which is used for cost and handling ease. While solutions like electronic and optical equalizers have been proposed, electronic devices are limited by processing speed, and many proposed optical profiles are difficult to implement. This study focuses on investigating the use of new optical fiber architectures, such as Few-Mode Fibers (FMF), Multi-Core Fibers (MCF), or hybrid fibers (MCF-FMF)—traditionally used with techniques like MDM or SWDM—to specifically mitigate the problem of modal dispersion compensation in MMF. The methodology involves an exhaustive state-of-the-art review, the development of mathematical and numerical models involving the MMF and the new fiber, implementation of these models in specialized simulation software for transmission scenarios, and dissemination of the results through scientific publications.<br/><br/><b>Goal</b>: <br/>The main objective is to increase the reach of a multimode fiber optic (MMF) network by implementing new optical fibers to upgrade its capacity and enable high bit rates, investigating the use of these new fibers to compensate for modal dispersion.<br/><br/><b>Research lines</b>: <br/>New generation telecommunications networks
