Power Transmission over Ethernet (Power over Ethernet (PoE)) is a technology that allows electrical power to be delivered to a remote device along with data through a standard twisted-pair cable in an Ethernet network. This technology is intended for IP telephony, wireless access points, IP cameras, network hubs, and other devices where running a separate electrical cable is undesirable or impractical.
This adapter is a PoE injector operating on Passive PoE technology, designed to power devices compatible with this technology. It is also worth noting that this injector allows simultaneous power delivery and gigabit network connectivity over a single twisted-pair cable.
