Re: IEEE 40GE & 100GE

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.
