Journal of Lightwave Technology, 39(13), 4262–4269.0733-8724https://hdl.handle.net/10016/33782We propose using power-over-fiber (PoF) in some part of future 5G cellular solutions based on radio access networks considering currently installed front-haul solutions with single mode fiber to optically power communication systems for 5G new radio (NR) data transmission. Simulations addressing design parameters are presented. Radio-over-fiber (RoF) transmission over single mode fiber (SMF) is experimentally implemented and tested for link lengths ranging from 100 m up to 10 km with injected PoF signals up to 2 W. 64QAM, 16QAM and QPSK data traffic of 100 MHz bandwidth are transmitted simultaneously with the PoF signal showing an EVM compliant with 5G NR standard, and up to 0.5 W for 256QAM. EVM of 4.3% is achieved with RF signal of 20 GHz and QPSK modulation format in coexistence with delivering 870 mW of optical power to a photovoltaic cell (PV) after 10 km-long SMF link. Using PoF technology to optically powering remote units and Internet-of-Things (IoT) solutions based on RoF links is also discussed.8eng© The authors, 2021.Atribución 3.0 España5GChromatic dispersionError vector magnitudePower-over-fiberRadio access networkRadio-over-fiberSmall cellresearch articleElectrónicahttps://doi.org/10.1109/JLT.2021.3074193open access4262134269Journal of Lightwave Technology39AR/0000028841
