What does the acronym "POE" stand for in networking?

The acronym "POE" stands for "Power Over Ethernet." This technology allows network cables to carry electrical power alongside data, enabling devices such as IP cameras, VoIP phones, and wireless access points to receive power directly through the Ethernet cable rather than requiring separate power supplies. This not only simplifies installation but also reduces cable clutter and allows for more flexible placement of devices.

Power Over Ethernet is particularly advantageous in scenarios where it may be difficult or expensive to provide power to a device, as in outdoor installations or areas without nearby power outlets. Employing POE can result in cost savings and improved efficiency in network setups, making it a widely adopted standard in networking.

Understanding POE is essential for technicians, as it affects cabling choices, installation planning, and troubleshooting in network environments.
