In this paper, we review the feasibility of simultaneously transmitting optical power and 5G NR data signals over a 20 km single-mode optical fiber. A power-over-fiber system was designed that combines a 5G NR signal at a Frequency of 3.5 GHz and a bandwidth of 100 MHz with a power signal of 1.5 W. The effect of linear transmission attenuation, as well as non-linear transmission effects such as stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS), was analyzed to evaluate their impact on data transmission quality and power transmission efficiency, succeeded in achieving high data transmission performance, with an EVM value of 3%. Additionally, an optical power of 585.3 mW was measured at the end of the optical fiber. These results confirm the feasibility of using the proposed system, paving the way for its application in 5G systems, particularly in RAUs.

摘要

In this paper, we review the feasibility of simultaneously transmitting optical power and 5G NR data signals over a 20 km single-mode optical fiber. A power-over-fiber system was designed that combines a 5G NR signal at a Frequency of 3.5 GHz and a bandwidth of 100 MHz with a power signal of 1.5 W. The effect of linear transmission attenuation, as well as non-linear transmission effects such as stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS), was analyzed to evaluate their impact on data transmission quality and power transmission efficiency, succeeded in achieving high data transmission performance, with an EVM value of 3%. Additionally, an optical power of 585.3 mW was measured at the end of the optical fiber. These results confirm the feasibility of using the proposed system, paving the way for its application in 5G systems, particularly in RAUs.
