What is Poe technology?

POE (power over Ethernet) refers to a technology of transmitting power through network cable. With the help of existing Ethernet, it can simultaneously transmit data and supply power to IP terminal equipment (such as IP phone, AP, IP camera, etc.) through network cable.

Poe is also known as power over LAN (POL) or active Ethernet, sometimes referred to as Ethernet power supply.

In order to standardize and promote the development of Poe power supply technology and solve the problem of adaptability between power supply and power receiving equipment from different manufacturers, IEEE standards committee has successively issued three Poe standards: IEEE 802.3af standard, IEEE 802.3at standard and IEEE 802.3bt standard.
