PoE cable bundles generate heat due to the power transmission that occurs through the copper conductors of standard networking cables. Wiring cabinets or networking sites that do not allow for proper heat dissipation can lead to cable bundles with higher-temperature cores. Cable bundles with higher temperature
IEEE’s 802.3at Power over Ethernet (PoE) standard helps network installers connect higher powered network applications that require up to 25.5 watts of power. But a new PoE standard, 802.3bt, is promising to deliver up to 100 watts of power to powered devices.
The 802.3bt standard has been in the works since 2013 and finalization is expected to occur on 2017. Even though IEEE has yet to finalize
