Achieving Optical Fiber Transmission of Over 60 W of Electrical Power and Optical Data

For future mobile communication networks, optically powered remote antenna modules are shown with simultaneous transmission of over 60 watts of electric power and optical data over an optical fibre. As the temperature rises over the set point, the light source undergoes modulation, causing a shift in wavelength. Fibre Bragg Grating Sensors are presented in this study, along with an examination of their design for use in measuring and monitoring powerline temperature change over a certain temperature range. In this piece, we enhance the link design to extract a greater feed light power from the double-clad fibre output, which in turn increases the provided electric power via power-over-fiber connection. Furthermore, we employ a bespoke photovoltaic power converter that directly converts optical power into electric power to increase the electric power for running remote antenna units. The photovoltaic power converter has an efficiency of more than 50% and can absorb feed light of more than 20 W. Up to 43.7 W of electrical power may be sent over the fibre optic cable thanks to the improved design of the power-over-fiber connection and the use of the solar power converter. Power-over-fiber with optical data transfers utilising a single optical fibre has been demonstrated for the first time at this altitude, according to the scientists.
