About Power over Ethernet Technology

PoE is a technology for wired Ethernet, the most widely installed local area network technology in use today. PoE allows the electrical power necessary for the operation of each end-device to be carried by data cables rather than by separate power cords. It minimizes the number of wires that must be used in order to install the network, resulting in lower cost, less downtime, easier maintenance and greater installation flexibility.
