Chris, Those were straw-man numbers. The point is that eventually it all becomes a commodity and mass-produced, and I'd like to see the stuff that would be maximally useful to us be the commodity that benefits most from the mass production. Hence my preference for the 10km optics. ---rob "Chris Cole" <chris.cole@finisar.com> writes:
Owen,
You are an optimist. Initially, the pricing will be more then an order of magnitude higher. :)

So, assuming this translates roughly to optics being:
$1,000 4km $1,300 10km $2,600 40km
You'd rather have to pay $2,600 for all your campus links than $1,300 for all your LAN links?
My preference would be quite different. I'd much rather pay $1,300 for the LAN links than $2,600 for the Campus links.

The 40km/10km cost ratio is between 1.6x and 2x, depending on the source.
The 10km/4km cost ratio is between 1.15x and 1.3x, again depending on the source.
If those numbers translate into prices (not costs), then I'd prefer to see 40km and 4km optics, with no 10km optics. The important point is that the 40km optics neet to be able to handle 4.1km links with no attenuators, preferably without any human tuning at all. You only pay the extra capital cost once (if there even is any, due to more volume of fewer parts), but you pay labor and sparing over and over.
