Detailed explanation-1: -Power over Ethernet (PoE) is technology that passes electric power over twisted-pair Ethernet cable to powered devices (PD), such as wireless access points, IP cameras, and VoIP phones in addition to the data that cable usually carries.

Detailed explanation-2: -Power over Ethernet (PoE) is a technology for implementing wired Ethernet local area networks (LANs) that enables the electrical current necessary for operating each device to be carried by Ethernet data cables instead of standard electrical power cords and wiring.

Detailed explanation-3: -Power over Ethernet (PoE) technology has been using Cat 5e/Cat 6 Ethernet cables to transport electric power over a single data connection for years. This technology allows for a safe and responsive installation that does a great job collecting data as well as transmitting power, all at a reasonable cost.

Detailed explanation-4: -Power over Ethernet (PoE) is technology that passes electric power and data over twisted-pair Ethernet cable to wireless access points, IP cameras, and VoIP phones. It enables one RJ45 patch cable to provide both a data connection and electric power to connected edge devices instead of having a separate cable for each.
