Steve, If we could just performance tune that
engine in the Smart car, then your concept might be
more compelling. I wish this could
be true. We would be finished with
this issue now. At present, however,
we have to find a new engine (improved VCSEL) and/or strap on rockets (FEC,
EDC), which doesn’t seem so Smart anymore. Jeff ———————————————— Jeffery J. Maki, Ph.D. Principal Optical

E [mailto:SwansonSE@xxxxxxxxxxx] Geoff, You know me - I like analogies; I seem to
remember using airplanes as an example during the development of 10GbE,
something like comparing 747s to regional jets. I also like automobiles so let
give you my take on where we are at as it relates to 802.3ba. I agree that the bulk of automobile
product line only has 5 passenger capacity. However, how many cars will you see
this morning on the way to work will have five people in them? Very few - most
will have one and some will have two. Using the 802.3ba philosophy, we would
standardize a two-seater since that is what the majority of the market needs.
We would ignore the typical sedan which gives broader market coverage at maybe,
just maybe a small premium. I view the XR variant as the typical sedan. We have an objective for Scooters - 10m of
copper - just get me from here to there at the lowest cost We have an objective for a Smart car -
100m of MMF - good enough for most commuters We have an objective for a Greyhound bus -
10km of SMF We have an objective for a turbo-charged
Greyhound bus (or a John Madden luxury liner or a 747) - 40km of SMF) But we have ignored the family sedan that
provides broader coverage at a reasonable cost. Our argument is that it is not
large enough or doesn't warrant the extra cost. I see 10-20% of a lot of ports
as much, much bigger than 100% of hardly any ports (albeit expensive ones). I
don't hear anyone talking about how small the 40km SMF market is. I still don't get it. Best regards, Steve From: Geoff

link lengths longer than 100m and want (or require) a standardized solution?
