Every year on the fourth Thursday of November, people in North America celebrate Thanksgiving. This holiday is not only a time for family reunions and feasts, but also an important reminder to be grateful and cherish the present moment.
PoE, also known as Power over Ethernet or Active Ethernet, is a technology that simultaneously transmits data and power over 10BASE-T, 100BASE-TX, and 1000BASE-T Ethernet networks, with a reliable power supply distance of up to 100 meters.
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.
