A PoE switch is a network switch that transmits both data and power over the same Ethernet cable. It can power connected devices such as wireless access points, network cameras, and IP phones, eliminating the need for additional power lines.
The China International Optoelectronics Expo is a premier event for the optoelectronics industry, and HSGQ had an impressive presence this year. HSGQ showcased its core product lines, including OLT GEPON, ONT, and SFP modules.
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.
