PoE 802.3at 802.3af
PoE Plus has vowed to provide the maximum power within practical limits. • Assuming that power delivery is ultimately limited by heating in the cable, this suggests that a 4-pair system is a necessary solution. • In the case of maximum delivered power, 4-Pair PoE can deliver about 50% more power than a 2-Pair PoE system. • This significant advantage of 4-Pair means that PoE Plus should define a 4-Pair PoE standard.
