Towards high bandwidth communication systems: from Multi-Gbit/s over SI-POF in home scenarios to 5G cellular networks over SMF

The main objective of the thesis is to study high bandwidth communication systems for different network architectures from the end user at the in-home scenario to the service provider through the mobile cellular front-haul network. This is in parallel with the integration of power over fiber (PoF) technology in these systems.The present work received funds from the following Spanish and international projects: - Spanish Ministerio de Ciencia, Innovación y Universidades, “Tecnologías avanzadas inteligentes basadas en fibras ópticas/Advanced SMART technologies based on Optical Fibers (SMART-OF)”, grant no.

SI-POF supporting power-over-fiber in multi-Gbit/s transmission for in-home networks

We propose the integration of power-over-fiber (PoF) in home networks with multi Gbit/s data transmission based on wavelength-division-multiplexing (WDM) in step-index plastic optical fibers (SI-POF). Different powering architectures are described. The efficiencies of different components are discussed to address the maximum remote energy that can be delivered. Experimental results show the ability of the system to deliver several mW of optical power with negligible data signal quality degradation and with BER of 1 × 10¿10. The potential of utilizing PoF in combination with low-loss WDM-POF to optically powering multiple devices for specific in-home applications and IoT ecosystems is discussed. A PoF scalability analysis is detailed.This work was supported in part by the Spanish Ministry of Science, Innovation and Universities under Grant RTI2018-094669-B-C3; in part by the Directorate for Research and Innovation at Madrid region under Grant Y2018/EMT-4892; and in part by the H2020 European Union 5G PPP Bluespace project under Grant n°.762055
