The main difference between PoE and PoE+ lies in the power supply and applicable scenarios.
Power supply
PoE: Based on the IEEE 802.3af standard, the maximum output power of each port is 15.4W, and the voltage range is 44V to 57V.
PoE+: Based on the IEEE 802.3at standard, the maximum output power of each port is 30W, and the voltage range is 50V to 57V.
Applicable scenarios
PoE: Suitable for devices with lower power requirements, such as ordinary IP phones and cameras. These devices generally do not require more than 15.4W of power support.
PoE+: Suitable for devices that require more power support, such as high-definition cameras and wireless access points. These devices generally require more than 15.4W but no more than 30W of power supply.
Technical advantages
PoE: It can ensure the safety of existing structured cabling. At the same time, it ensures the normal operation of the existing network. It can minimize costs. At the same time, it eliminates the need for additional power wiring, making network deployment more flexible and convenient.
PoE+: Inherits all the advantages of PoE and provides higher power to meet the needs of more devices. It also has the advantages of cost savings and flexible deployment.
