[[File:ZyXEL ZyAIR G-1000 and D-Link DWL-P50 20060829 2.jpg|thumb|300px|In this configuration, an Ethernet connection includes Power over Ethernet (PoE) (gray cable looping below), and a PoE splitter provides a separate data cable (gray, looping above) and power cable (black, also looping above) for a [[wireless access point]].  The splitter is the silver and black box in the middle between the wiring junction box (left) and the access point (right).  The PoE connection eliminates the need for a nearby [[power outlet]].  In another common configuration, the access point or other connected device includes internal PoE splitting and the external splitter is not necessary.]]

'''Power over Ethernet''' ('''PoE''') describes any of several [[technical standard|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 point]]s (WAPs), [[IP camera]]s and [[VoIP phone]]s.
