I doubt any such data exists, but I wonder how many fiber miles and custome=

I can provide you some advice from a local person in my area that is doing =
this, while homes aren=E2=80=99t of such a nice identity of 10 meters, they=
place a pedestal that has capacity for 96 count splice trays at every 3rd =
home. You can use something like a flat drop cable to be buried later as th=
at connection. They may also drill up to the home or use a maxi or mini-sne=
aker type device to directly place the duct in the ground from that pedesta=
l.=20
The bonus of this type of solution is in the winter months where the ground=
is frozen you can often leave this cable on the ground to be buried at a l=
ater date. I helped a local WISP turn up their first fiber link in the past=
two weeks and this was the strategy they took.=20
