What does the abbreviation PoE stand for?

The abbreviation PoE stands for Power over Ethernet, which refers to a technology that allows electrical power to be transmitted along with data over standard Ethernet cabling. This capability is particularly useful for powering devices such as IP cameras, VoIP phones, and wireless access points without the need for separate power supplies.

Power over Ethernet simplifies installations by reducing the number of cables required and allows for greater flexibility in positioning devices where electrical outlets may not be readily available. By using a single cabling infrastructure, it enhances efficiency and can lead to cost savings in both materials and labor.

The other options do not represent established terminologies or technologies related to Ethernet, which is why they are not correct in this context.
