The problem is that if you break down the costs, you'll find out that
it almost doesn't matter what you put in as a cost of the total build;
the big costs are the engineering and the labor to install, not the
"cost of the NID" or anything like that. Nobody cares whether you
saved a million bucks on a 2 billion dollar project.
One of the cool things about the infrastructure that is now in place
(copper pairs) is that it turned out to be relatively future-proof -
lots of 50 and 70 year old OSP still in use. In order to get
similarly long life out of newly installed fiber assets, the only real
solution is home runs to either existing or newly constructed
concentration points (not just a box at the side of the road, that's
not what I'm talking about here). Distributed splitter designs force
forklift upgrades when the Next Big Thing comes along, rather than
upgrading the service only for folks who are willing to pay for it.
The Next Big Thing is always coming, and 2.4 Gbit/sec down per port
GPON is gonna look awfully slow 10 years hence when everyone's
demanding gigabit ethernet to the desktop, not to mention 20 years
from now with IPv6 multicast of 2000 channels of 4320p pr0n.
I used to believe in the FTTC (fiber to the curb) model too - it's the
"obvious" solution. That was before I started cranking the numbers
myself, playing with some of the new splicing solutions that are out
there that require *far* less finesse than the cam-splice stuff I was
using 10 years ago. Now I believe in the "other" FTTC (fiber to the couch).
Get it as far out into the field as you possibly can, right up to,
or even inside, the house.
