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.
