Power Over Ethernet (PoE) Calculator
Temperature rise in structured cabling networks have a negative impact on performance and reach.
This includes category cables and connectors typically used in enterprise commercial buildings
under various installation conditions and ambient temperatures. Using this calculator allows the
cabling to be designed, installed and operated to optimize thermal and electrical performance
in different configurations. This tool should be used as a reference following ISO/IEC 14763-2,
EN 50174-1 and EN 50174-2: guidelines to support delivery of power using all four pairs with up
to 1000 mA per pair (500 mA per conductor) for a maximum power of 100 VA (100 watts) at the power
source over four-pair cabling. Installations within the boundaries calculated with this tool can
be marked RP3 according to the standards above.
