PoF

What is Power over Fiber?

PoF is a technology that uses optical fiber to simultaneously transmit data and power. It may sound a bit surprising, but its core principle is:

• Energy transmission through optical fiber: At the transmitting end, a highly efficient photoelectric converter converts electrical power into high-intensity laser light.

• Laser transmission through optical fiber: This laser beam is transmitted to a remote device via a specialized optical fiber (usually glass fiber, as it can handle higher optical powers).

• Photoelectric conversion: At the receiving end, a photovoltaic cell or photodiode converts the received laser light back into electrical energy to power the device.

PoF is like a "light cable," achieving the dual functions of "data + power" through a single optical fiber.
