What does PoE stand for in the context of cabling?

Power over Ethernet (PoE) refers to a technology that allows network cables to carry electrical power alongside data to devices. This is particularly beneficial for devices such as IP cameras, VoIP phones, and wireless access points, enabling them to operate without requiring a separate power source. Utilizing PoE simplifies installation and reduces the complexity of wiring infrastructure, as it consolidates both data and power delivery through a single cable.

The application of PoE facilitates a streamlined setup in environments where power outlets may be limited or impractical. By sending power directly over the Ethernet cabling, this technology enhances the efficiency and flexibility of network installations. Additionally, PoE standards like IEEE 802.3af and IEEE 802.3at define the means and power levels that can safely be transmitted over these cables, ensuring compatibility and safety across devices.

In contrast, the other options do not accurately represent the function or application of PoE in cabling.
