The abbreviation POE in relation to cabling refers to "Power over Ethernet." This is a technology that enables network cables, specifically Ethernet cables, to carry electrical power along with data. This capability allows devices such as IP cameras, VoIP phones, and wireless access points to receive power directly through the Ethernet cable, eliminating the need for a separate power supply.

Understanding Power over Ethernet is essential for modern networking, as it simplifies installations and reduces the number of cables required. PoE can also enhance device flexibility, allowing them to be placed in locations that may not have easy access to power outlets. The technology follows specific standards, such as IEEE 802.3af and 802.3at, which define power delivery and ensure safety and compatibility among different devices.
