Differences between PoE, PoE+ and PoE++ Switches
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. PoE switch use two pair 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.
Applications of PoE Switches, PoE+ Switches, and PoE++ Switches
PoE switches can be used to power a wide range of surveillance as well as audio-visual equipment in commercial facilities.
PoE switches | · VoIP phones operated across offices · Pool pumps, cameras, lighting installations, and digital signage on the sides and tops of skyscrapers · Audio visual equipment in stadium and indoor spaces · Wireless access points for small networks, RFID readers, wireless network repeaters · Stationary cameras as well as cameras with no PTZ features · Solar power equipment in commercial and industrial spaces |
PoE+ Switches | · Office or home alarm systems · Biometric sensors · Motion tracking cameras installed in commercial premises · Remotely managed PTZ cameras · Remote computer terminals · IP telephones for voice calls, text messaging, and fax |
PoE++ Switches | · Video telephones · Thin clients (small computer) · Door access systems or gate controllers · Remote patient monitoring devices |
Note: PoE switches are not recommended for data transfer over long distances or in applications where ambient temperature conditions may be present. Both these factors can have an impact on these switches.
