Power‐over‐fibre for wireless applications

Abstract

This paper demonstrates the use of the power-over-fiber concept for wireless applications, which removes the need for DC power supplies at the remote network. The article shows results using low cost lasers, photodiodes, a highly efficient voltage booster circuit (>80%), and rechargeable batteries. Results show that with the best choice of each component, the system can operate for 8 h per day over 200 m MMF for 41 days. System modeling shows that the system can operate indefinitely for 5 h a day over 200 m MMF. Finally, the system was tested for a 802.11 g WLAN application over 200 m MMF and a maximum range of 4 m at 500 kbps can be obtained.

Research on the key technology of power over fiber transmission based on OPGW power cable

“…Then the remaining laser power in the remote station is converted to electrical power by photovoltaic cells. It also has internal features such as immunity from electromagnetic noise and interference, no potential danger of fire or explosion caused by electric sparks, electrical insulation between both ends of the link [7]. With the rapid development of semiconductor lasers and optical fibers, PoF technology has been widely used in various fields [8].…”
