PoE standards such as IEEE 802.3af (PoE), IEEE 802.3at (PoE+), IEEE 802.3bt (PoE++) define parameters for delivering power over Ethernet cables. These standards ensure compatibility between different devices and power sources and specify the maximum amount of power that can be supplied. Standardizing PoE makes it easier to implement and manage power for different network devices, which increases the security, efficiency, and flexibility of network installations.
