Power Over Fiber and Analog Radio Over Fiber Simultaneous Transmission Over Long Distance in Single Mode, Multicore, and Hollow Core Fibers

In this work, a novel study of the feasibility of shared Power over Fiber (PoF)and Fifth-Generation (5G) New Radio (NR) Analog Radio over Fiber (ARoF)over long distance Hollow-core Fibers (HCF) is presented. Comparativemeasurements between similar lengths of HCFs, Multicore (MCF) and SingleMode Fibers (SMF) are performed. A complete analysis on the StimulatedRaman Scattering (SRS)-induced noise transfer from PoF to ARoF is tackled.Relative Intensity Noise (RIN) of ARoF signals is measured for all the opticalﬁbers tested, observing no degradation in HCFs, neither on MCFs andsigniﬁcant deterioration in SMFs. A combination of PoF and 5G NR ARoF linkin a single ﬁber is implemented, and 5G NR signals with diﬀerent modulationformats are successfully transmitted through HCFs and MCFs withoutdegradation, while SRS-induced noise transfer in SMFs massively deterioratethem. PoF transmission eﬃciencies are also analyzed, achieving up to 9.9 %System Energy Eﬃciency (SEE) for a 3.1 km HCF, 0.9 % for a 11.1 km HCFand 1.5 %, 13.5 %, and 20.4 % in a 10 km MCF, a 9.8 km SMF and a 3.3 kmSMF, respectively. The PoF signal is used to supply a Bluetooth Low-Energy(BLE) load with a power consumption of ≈ 20 mW.
