ComparePoE (802.3af)
9 specs
Power over Ethernet (PoE, IEEE 802.3af Type 1) is a 2003 networking standard that delivers up to 15.40 W of direct current (DC) power from a Power Sourcing Equipment (PSE) port, guaranteeing 12.95 W of usable power at the Powered Device (PD) over two twisted pairs.
PoE+ (802.3at)
9 specs
Power over Ethernet Plus (PoE+, IEEE 802.3at Type 2) is a 2009 standard delivering up to 30.0 W of DC power per PSE port and guaranteeing 25.50 W of continuous power at the connected Powered Device (PD) across two twisted pairs of Category 5e or better cable.
PoE++ Type 3
10 specs
Power over Ethernet Plus Plus Type 3 (PoE++ / 4PPoE, IEEE 802.3bt Type 3) is a 2018 standard that supplies up to 60.0 W of DC power per PSE port and guarantees 51.0 W of usable power at the PD by transmitting current across all four twisted pairs simultaneously.
PoE++ Type 4
10 specs
Power over Ethernet Plus Plus Type 4 (High-Power PoE++, IEEE 802.3bt Type 4) is the highest standardized PoE tier, delivering up to 90.0 W (and up to 99.9 W maximum) from the PSE to guarantee 71.3 W of DC power across all four pairs to high-draw client hardware.
