IEEE Forms 4-Pair Power-over-Ethernet Group

The IEEE has established a new study group to consider initiating a formal project to standardize 4-pair Power over Ethernet (PoE).

A 4-pair Power over Ethernet implementation could provide greater than 25.5 Watts of power.

"The formation of this study group will allow collaboration on a proposal for the development of a 4-pair PoE standard, which would allow support of new PoE applications in the areas of IPTV, industrial Ethernet and more," said David Law, chair of the IEEE 802.3 Ethernet Working Group and distinguished engineer with HP Networking. "A 4-pair approach would result in increased efficiency, since the use of additional pairs results in lower channel resistance."
