Research at the University of Electro- Communications demonstrates a high power supply over the same fiber used for data transmission

摘要

Increasing data use is placing greater demands on the radio antenna units that transmit data to mobile devices. Supplying power to these antenna units by the same optical fiber systems that transmit data signals to them could improve and simplify these infrastructures if the power supplied this way can be increased. Now Motoharu Matsuura, Hidehito Furugori and Jun Sato at the University of Electro-Communications have demonstrated the ability to supply 60 W over a 300 m test fiber system, exceeding the power supplied in previous work and emphasizing the potential of the approach.
