Outline of Final Research Achievements |
We have conducted research and development on power-over-fiber technology for mobile communications. In this research, we achieved the following three major results. 1) We constructed an optical fiber power feed system capable of electric power feeding, and achieved 7 W electric power transmission simultaneously with multi-channel optical signals. 2) As a part of the evaluation of the extreme performance of the proposed power-over-fiber system, we constructed an power-over-fiber system using 150 W of power feed light, which is much higher than the previous system, and clarified that excellent stability and high power/signal transmission characteristics can be obtained. 3) By summarizing the previous findings and technologies, we demonstrated an power-over-fiber technology that can supply 43.7 W of electric power.
