Siemon IEEE 802.3at PoE Plus Operating Efficiency

The development of the pending PoE Plus standards brings to light a significant new challenge in delivering power over a structured cabling system. The higher power delivered by PoE Plus devices causes a temperature rise within the cabling which can negatively impact system performance. The information in this paper will allow readers to be better equipped to make PoE Plus-ready cabling choices that will support reduced current-induced temperature rise and minimize the risk of degraded physical and electrical performance due to elevated temperature.
