What does Power over Ethernet (PoE) allow devices to do?

Power over Ethernet (PoE) allows devices to receive both power and network data over a single Ethernet cable. This technology is particularly useful for devices that may not have direct access to a power outlet, such as IP cameras, VoIP phones, and wireless access points. By using standardized cables, PoE streamlines installation, reducing the need for separate power cabling and the complexities that come with managing multiple cables.

This capability simplifies network infrastructure and enhances flexibility in terms of device placement. Rather than needing to install electrical wiring for each device, they can be positioned based on network needs, while still receiving power and data through a single Ethernet connection. In this manner, PoE supports both power delivery and data communication seamlessly, making it a versatile solution for modern networking environments.
