Study of Next-Generation Access Optical Networks to Determine Their Effectiveness and Viability for Responding to Ultra-Broadband Demands

This project addresses the critical need for new optical access technologies to meet the growing bandwidth demand driven by advanced applications and IPv6. The focus is on evaluating the effectiveness and viability of next-generation optical access networks, such as NGPON2 and the 802.ca standard, which aim for speeds up to 100 Gb/s using technologies like DWDM and WDM/TDM. Various architectures are investigated, including those based on pure WDM, tunable sources, and the use of low-cost components like those proposed in the COCONUT project. Furthermore, solutions for extending reach (LR-PON) using Reflective Optical Amplifiers (RSOA) and techniques like RZ modulation are explored. Although coherent transmission offers the best performance, its high cost remains a barrier. The methodology involves an exhaustive state-of-the-art investigation in databases like ScienceDirect and IEEExplore, followed by the design and mathematical modeling of transmission and optimization schemes using specialized software such as MatLab, Python, OptSym, or VPI-Photonics. Finally, simulation results will be experimentally validated to generate relevant conclusions and scientific publications.<br/><br/><b>Goal</b>: <br/>To study next-generation optical access networks (NG-PON) to determine their effectiveness and viability in meeting the growing demands for ultra-broadband, by analyzing new transmission techniques and optimization models.<br/><br/><b>Research lines</b>: <br/>Telecommunications and information technologies
