PoE technology facilitates the transfer of power and data over Ethernet cabling using PoE devices such as injectors, switches, and splitters.

PoE injectors are generally categorized based on the output power voltage they can provide, with 12V, 24V, and 48V being the most common options.

The PoE injector is a useful device that can provide power to standard-based PoE, PoE+, and PoE++ compliant devices while also sending data.
