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.
