The Tenda PoE30G-AT is an IEEE802.3at Gigabit PoE injector that fully complies with the 802.3at standard. This allows voltage to be transmitted over an Ethernet cable up to a maximum distance of 100 meters. The PoE Injector has two Ethernet Gigabit data ports and an output, combined data and voltage port. The device delivers IEEE802.3af/at-compatible PoE power supply to Ethernet devices, such as wireless access points, VoIP phones and web cameras. The PoE30G-AT supplies the voltage via an Ethernet cable, which on the one hand enables the creation of a reliable system and the expansion of the traditional electrical network, and on the other hand simplifies the construction of electrical wiring.
