PoE: The 802.3bt standard that pushes Power over Ethernet up to 100W
Since January 2019, the IEEE body ratified the new 802.3bt norm. The maximum Powered Device (PD) power available is increased to a 100W by utilizing all four pairs in the specified structured wiring plant. This represents a substantial change to the capabilities of Ethernet with standardized power. The power classification information exchanged during negotiation is extended to allow meaningful power management capability. These enhancements solve the problem of higher power and more efficient standardized Power over Ethernet (PoE) delivery systems. Energie IP was first to realize the potential of the newly ratified norm and has intergated it into its PoE based BMS solution.
