This is by no means crazy.  If you visit a laboratory where gear is
tested, you'll find exactly that -- spools of fiber which can be
connected together (through whatever splicing or patching method is
desired for the simulation) to give the desired span length.  These
usually look nicer than big spools of cable, and are even available in
rack-mount enclosures with vendor logos. :)

one does not however do 2200 miles of terrestrial fiber simulation
without simulating regeneration as well.
