What is Power over Ethernet?

In this blog, read about the advantages of Power over Ethernet, the IEEE 802.3 standard, and what’s next for PoE.

Power over Ethernet means an Ethernet cable is used for two purposes: a network connection and a power source. Devices that utilize PoE include computers, VoIP phones, cameras, kiosks, digital signage, industrial controls, network routers, and other IoT devices. PoE is often used on manufacturing and assembly lines, where dozens of devices are used to monitor and record data, and in security systems where cameras and other devices must be connected to the system from a great distance.

In this article, learn where PoE is used, how it works, PoE standards including 802.3, PoE+ and PoE++, and what to expect from this technology in the future.
