What does PSE stand for in PoE terminology?

Explanation:
Power Sourcing Equipment is the device that provides power to a PoE-enabled device over the Ethernet cable. This source sits on the power supply end of the link, and it can be a PoE-capable switch (endspan) or a separate midspan injector. Before delivering power, the PSE performs a detection and classification process with the powered device to ensure a real PD is connected and to determine how much power can be safely supplied. This negotiation, used across standards like 802.3af, 802.3at, and 802.3bt, ensures the right amount of power is allocated without harming the switch, the injector, or the connected device. The term distinguishes the power source from the powered device on the other end of the link.
