What Is Power over Ethernet (PoE)? - How-To Geek
2021年7月6日 · Power over Ethernet, or PoE for short, is a method of providing both power and networking to a device via network cabling. Just like with wireless networking, there are different standards for various PoE implementations, with newer standards providing more power for more demanding devices.
Power over Ethernet - Wikipedia
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 .
What Is Power over Ethernet (PoE)? - Cisco
Power over Ethernet (PoE) is a technique for delivering DC power to devices over copper Ethernet cabling, eliminating the need for separate power supplies and outlets. While PoE doesn't add Ethernet data capabilities, it does offer expanded options for how and where Ethernet end devices can be placed.
