Power-over-fiber, or 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 supply. Such systems can be used to protect the power supply from dangerous voltages such as from lightning, or to prevent voltage from the supply from igniting explosives. Power over fiber may also be useful in applications or environments where it is important to avoid the electromagnetic fields created by electricity flowing through copper wire, such as around delicate sensors or in sensitive military applications.

Safety protection method for optical fiber power supply system
The application discloses a safety protection method suitable for an optical fiber power supply system, wherein a gateway device sends a ranging request signal to a terminal device according to a preset frequency and provides optical energy required by the terminal, and determines the sending time, signal power and modulation mode of the terminal device according to the transmission quality of the ranging request signal. The gateway device can adjust and alarm a request signal through the terminal device, can realize real-time sensing of the change of optical energy signal transmission parameters of an optical fiber channel when remotely providing electric energy for the intelligent terminal in the optical fiber power supply communication system, so that the gateway device and the terminal device provide electric energy to an external intelligent device in an optimal mode, and mutual matching of the change of optical energy power output by the gateway and the power parameter of the external intelligent device is ensured.
