Re: [802.3_DIALOG] [STDS-802-3] Call for interest - 40Gb/s Ethernet Single-mode Fibre PMD
Dear Colleagues,
I received the following comment from Geoff Thompson in response to the
40Gb/s Ethernet Single-mode Fibre PMD Call for Interest announcement. To
keep the email burden low this IEEE 802.3 reflector is only used for
announcements and hence is not the appropriate venue to discuss this
issue. Since there wasn't really anywhere else that was appropriate I have
taken the step of setting up an IEEE 802.3 general discussion reflector at
the email address [stds-802-3-dialog@ieee.org] which I have CCed this
message to.
The IEEE 802.3 general discussion reflector is an opt-in reflector so if
you wish to discuss this issue please subscribe to the IEEE 802.3 general
discussion reflector at the URL [
http://www.ieee802.org/3/dialog_reflector.html ] or follow the discussion
in the reflector email archive at the URL [
http://www.ieee802.org/3/email_dialog/thrd1.html ].
Best regards,
David
