Pete, Appreciate the email explaining it all. We value your expert contributions in the
SG. -Roger From: Pete Anslow
[mailto:pja@xxxxxxxxxx] Roger, Thanks for your excellent
minutes. In the discussion section
on Presentation #21 it says: “PMD tolerance
should say Mean DGD” I think that this should
read “PMD tolerance should say Max. DGD”. John D’Ambrosia
tells me that the way to deal with this is to make a motion requesting this
change at the next meeting in Background for those not
at the meeting - The Max DGD specification for many 10 Gbit/s NRZ interfaces is
30 ps. One would therefore expect a 100 Gbit/s NRZ signal to have a factor of
ten smaller tolerance than this which agrees with the 3 ps number in
duelk_01_0906.pdf. The term “PMD tolerance” usually means
Mean DGD and would be expected to be a factor of at least 3 smaller than this
at about 1 ps. Pete Anslow Nortel Networks UK Limited, External +44 1279 402540 Fax +44
