Short-Reach Multimode Fiber Optic Network Upgrade for High Bit Rates (Phase 4)

This research project focuses on addressing the bandwidth and reach limitation in legacy multimode optical fiber (MMF) networks, caused by high modal dispersion, which prevents achieving the high bit rates (up to 100 Gbps) demanded by modern services like real-time applications and server farms. The problem is exacerbated in systems using MMF due to its inherent modal dispersion. The proposed solution investigates the use of new optical fibers, such as few-mode fibers (FMF) or modal adapters, acting as optical equalizers to compensate for modal dispersion. The methodology includes an exhaustive review of the state-of-the-art, the development of a mathematical model for equalization based on the new optical fiber, and the generation of numerical simulation scenarios to evaluate performance. The main objective is to increase the reach of these MMF networks by upgrading them to high bit rates, with the hypothesis of achieving a 10% increase in reach through compensation using a new equalizing optical fiber. The primary expected outcome is the dissemination of findings in a scientific article indexed in Scopus.<br/><br/><b>Goal</b>: <br/>To increase the reach of a multimode fiber-based network by using new optical fibers to upgrade it to high bit rates.<br/><br/><b>Research lines</b>: <br/>New generation telecommunications networks
