Fiber optic module transmit optical power
Power-over-fiber (PoF) is a technology in which a fiber-optic cable carries optical power, which is used as an energy source rather than, or as well as, carrying data. This allows a device to be remotely powered, while providing electrical isolation between the device and the power. Our patented Power Over Fiber (PoF) system provides power transmission over three multimode (62. The PoF system is able to provide true isolated power to a remote location utilizing Laser Light at the transmitter and a photovoltaic power converter at the remote location. Power meters generally have modular adapters that allow connecting to various types of connectors.
