Power over Ethernet (PoE)

1. What is Power over Ethernet?

Power over Ethernet (PoE) describes several standards or ad hoc systems for transmitting power and data over twisted-pair Ethernet cables. Power over Ethernet (PoE) is the process of transmitting both power and data over copper wiring. By combining data transmission and power supply hardware on the same RJ45 Ethernet connector, power can be delivered over the network cable.

2. How does Power over Ethernet Work?

Power over Ethernet (PoE) is a technology that transmits both power and data over Ethernet cables. It eliminates the need for an external power supply and makes it easy to install devices in locations where power outlets are inconvenient. The technology works by utilizing the unused wire pairs in the Ethernet cable to power devices. Power is transmitted from the power source to the device via the twisted copper wires, which then operate.
