[802.3af] FW: [10GBASE-T] Power over the MDI...
10GBASE-T is beginning to formulate objectives, and is trying to decide if
compatibility with 802.3af should be one of them. I am forwarding this
request from Brad Booth, Study Group Chair of 10GBASE-T, for your
It would be of great value to 802.3 for 10GBASE-T to be 802.3af compatible.
Therefore, I would propose that our TF do a short presentation to the
10GBASE-T SG at the March Plenary. This presentation should contain a quick
overview of DTE power, a discussion of signal-pair power (with emphasis on
the magnetics and power supply noise parameters), and a summary. It should
be short and concise, and will hopefully serve as an executive summary of
the possible compatibility issues.
Please let me know if you would like to work on this presentation.
See you at DFW,

Study group members,
As some of you may know, 802.3af is starting to wind down and getting closer
to completion. For those that do not know what 802.3af is, it is the
specification for transmitting power to the DTE over the medium. The study
group needs to decide whether or not compliance with 802.3af is within the
scope of our effort. This relates to compatibility with our existing
standards. If there is anyone that would like to make presentations for or
against compliance with 802.3af, please let me know.
Chair, 10GBASE-T Study Group
