[c-nsp] DWDM optics on 6500s

[Tony Varriale]

Yup!  No 80g cards yet.  I haven't been debriefed on the architecture but 
I'm assuming it is going to be 2 x 40g or 4 x 20g backplane lanes.

Thanks.  I assume that even though the 6509-V-E is available, until the 
80gig line cards and Sup are available, you'd be stuck at 40gig/slot?

It will shortly but it won't do you any good with the existing family of
sups.  The 2T will be the first (and last?) sup that can push the bandwidth
to all those slots.

You can also reference the 6509-V-E...it's ready for 80gbps/slot.  You can
order that today.  Note that it's a NEBS chassis.
