PD Type PD Power Cable Category Classes
Type 1 up to 12.95 Cat 3 and Cat 5 2 pairs class 1-2
Type 2 up to 25.5W Cat 5 2 pairs class 3-4
Type 3 40 – 51 W Cat5e 4 pairs class 5-6
Type 4 62 – 71 W Cat5e 4 pairs class 7-8
Type 1 : Also known as PoE, 2-pair PoE. Related standard: IEEE 802.3af. Maximum power to port: 15.4W.
PoE Type 1 utilizes two pairs to connect many types of lower-powered devices to the network. Based on the
initial IEEE 802.3af-2003 standard, it provides up to 15.4W of DC power to each PoE port (up to 12.95W of
power for each device). PoE Type 1 can support devices such as VoIP phones, sensors/meters, wireless access
points with two antennas and simple, static surveillance cameras (no pan, tilt or zoom).
Type 2
: Also known as PoE+, and PoE Plus. Related standard: IEEE 802.3at. Maximum power to port: 30W.
Higher-powered devices are connected to the network using PoE Type 2, based on the IEEE 802.3at-2009
standard. It is backward compatible (supports PoE Type 1 devices) and provides 30W of DC power to each PoE
port (up to 25.5W of power for each device). PoE Type 2 can support devices such as more complex surveillance
cameras that pan, tilt or zoom, as well as wireless access points with six antennas, LCD displays, biometric
sensors, and tablets.
Type 3 : Also known as 4-pair PoE, 4P PoE, PoE++, and UPOE. Related standard: IEEE 802.3bt. Maximum power
to port: 60W. PoE Type 3 uses all four pairs in a copper cable. Currently in development with IEEE 802.3bt Type 3
Work Group. It provides 60W of DC power to each PoE port (up to 51W of power for each device). PoE Type 3
can support devices such as videoconferencing system components and building management devices.
Type 4: Also known as higher-power PoE. Related standard: IEEE 802.3bt. Maximum power to port: 90W.
Growing power requirements of network devices are pushing the need for higher power delivered through
network cabling – which is where PoE Type 4 comes into play. It provides up to 90W of DC power to each PoE
port (up to 71W of power for each device – see IEEE 802.3bt Annex Clause 145.3.8.2.1 - Input average power
exceptions). PoE Type 4 can support devices such as laptops and TVs.
