Re: PMD discussion
Roy,
I'm not sure where your confusion is coming from, please explain.
All initial LAN WDM PHY proposals as well as those currently in front of the
Task Force employ 8B/10B encoding. This coding choice has been essentially
stable for more than a year now. 64B/66B has never been formally proposed as a
PCS for LAN WDM PHYs.
64B/66B has been proposed as the PCS for the LAN Serial PHY since approximately
the November, 1999 meeting.
Best Regards,
Rich
