PoE vs PoE+ vs PoE++ - Know the Real Difference

The following are some important pointers that will help you understand the difference between these switches.

• One of the major differences between PoE, PoE+, and PoE++ switches is the IEEE standards. A PoE switch is designed as per 802.3af, PoE+ as per 802.3at, and PoE++ as per 802.3bt.


• Next, Ethernet cabling is an important consideration when differentiating these switches. The PoE switch uses two pair of twisted cables, and the same goes for the PoE+ network switch. On the other hand, PoE++ uses four pairs of twisted cables. 


• Differences among these switches lie in the maximum power supply delivered by each port and their working mode, which reflect on their applications. PoE switches are designed to support network devices that require a power supply of up to 15.4watts. The list includes sensors, meters, wireless access points, surveillance systems, and many more. PoE+ switches support devices such as video IP phones, wireless access points with multiple antennas, and complex surveillance cameras. PoE++ switches can support devices that need higher power wattage such as video conferencing system components and building management devices, laptops, televisions, and so on.
