FCCs RFC for the Definition of Broadband

Perhaps the most practical service for both broadband and ALWAYS-on voice
service is one pair of copper (POTS) and one pair of fiber everything-else
per house.

Does anyone have a ballpark guess on the incremental cost of a strand-mile
(assuming the ditch is going to be dug and the cable put in it, how much
does the per-mile cost of the cable go up for each additional strand in it)
?

If the fiber pair goes all the way from some reasonably concentrated
location to the house, then excessive locations with batteries should not be
required.
