Four pair cable is required by the IEEE standards. A Hi-PoE PSE provides a maximum of 100 watts of power. A PoE+ PSE provides a maximum of 30 watts of power at 48vDC.
A PoE PSE provides a maximum of 15.4 watts of power at 48vDC. The PSE provides the power and the PD accepts the power. There are two main types of devices used in a PoE environment - the Power Source Equipment (PSE) and the Powered Device (PD). Additional advantages include greater flexibility for the location of installed equipment, less downtime, lower wiring costs, and lower power costs.
PoE, sometimes referred to as “inline power”, significantly reduces the number of wires that must be strung to install a network.

PSE Output Power to Dual-Signature PD (per pairset)ĭual-Signature PD Input Power (pairset / total) The differences between IEEE PoE standards are: IEEE PoE Specifications for Cat5e / Type The Hi-PoE standard is backward compatible with the existing PoE and PoE+ standards and helps to expand the adoption of standard PoE products and increase the demand for PoE powered products. With the ratification of the IEEE 802.3bt High Power PoE (Hi-PoE) standard in 2018, which can deliver up to 100W per port, there is now alignment between Hi-PoE vendors and no more compatibility issues between their products.
However, for PoE above 30 watts vendors began developing proprietary, non-interoperable (UPoE, 4PPoE, PoE++, UltraPoE, 4 Pair PoE, etc) implementations that made deployments of multiple vendor product solutions difficult. Using these standards, organizations commonly deployed equipment in locations that are difficult or too costly to have separate AC power installed - such as ceilings, walls, and kiosks. Since 2003, the PoE (IEEE 802.3af) and PoE+ (IEEE 802.3at) standards have been conveniently used to power and connect network devices that required voltage up to 30 watts. Similar to the way the wire pair that carries your POTS (Plain Old Telephone System) telephone signal into your house provides sufficient power for the headset, dial, and ringer systems for your telephone, PoE delivers DC power over standard Ethernet cabling (CAT3 and better).
