Power over Ethernet (PoE) describes any of several standards or ad hoc systems that pass electric power along with data on twisted-pair Ethernet cabling. This allows a single cable to provide both a data connection and enough electricity to power networked devices such as wireless access points (WAPs), IP cameras and VoIP phones.

Mar 28, 2025 · Smaller gauge cables carrying PoE can heat up and cause increased insertion loss, preventing proper data transmission. Heat rise is especially a concern in bundles of closely packed cables carrying higher levels of PoE, which is why the NEC specifies bundling requirements for Type 3 and Type 4 PoE based on the cable gauge and temperature rating.

Power over Ethernet (PoE) is a standard that allows Ethernet cables to transmit data and power simultaneously using a single network cable. This allows system integration and network installers to deploy powered devices in locations that lack electrical circuitry.
