PoE+ technology (IEEE 802.3at standard) is an upgraded version of PoE technology, released in 2009. PDs on the market tend to require higher wattages, for example wireless access points require more than 12.95W of PoE wattage to function properly. To solve this problem, PoE+ technology was created to support high power consumption.

Similar to PoE network switches, PoE plus switches are powered through two pairs, but it adds an extra power level capable of delivering up to 25.5W of power to PDs with voltages ranging from 42.5V to 57V. PoE+ switches provide a maximum of 30W per port for a voltage range of 50V to 57V.

What are PoE++ and PoE++ switches?

In order to provide more power to a wider range of device applications, the IEEE 802.3 standard once again calls for an upgrade of its PoE+ technology to PoE++ (IEEE 802.3bt standard) in 2018.PoE++ can be divided into two types: Type 3 and Type 4. Type 3 enables two or all four twisted pairs in a copper cable to provide up to 51W on a PD power on the PD. Type 4 enables up to 71W of power over the PD via four twisted pairs in an Ethernet cable.

PoE++ network switches are the next generation of PoE+ technology. PoE++ switches support up to 60 watts per port under Type 3 and provide the highest level of power for Power over Ethernet switches - up to 100W per PoE port under Type 4.
