What? $300,000,000 divided by (5280*6200) = $9.16/ft.
EDIT: ahhh per mile. My bad.
9.16 was rounded, *5280 = $48,364.80/mile.
Edit2: Which isn't astonishingly more than general zip cord fiber (ie patch cable), which is on average $5.20/ft. So take into account the armoring for that cable, and you have an idea.
