Yeah, the cost isn't that much higher for the fiber...

Still, typical FTTH deployment uses a network architecture known as PON
(Passive Optical Network).  The wikipedia article on the matter is fairly
accurate, for the interested  (
http://en.wikipedia.org/wiki/Passive_optical_network)

PON is basically a broadcast-style design that is not too different than a
cable HFC plant architecture; the same data gets sent to all connected units
by being split out optically at the neighborhood.

PON does save a significant amount of money; lower fiber costs just being
one.  Good fiber equipment (for terminating fiber) is quite expensive
still.   Management/maintenance is the other.  The main disadvantage
(long-term) is the upstream capacity....

The alternative designs would run as follows:
1. Each customer has a unique fiber run all the way back to the head end /
co.  This is complicated for a lot of reasons (in terms of line
maintenance), becomes cost proh. quite quickly just on the fiber (it's not
_that_ cheap, even if it's not very expensive).  The biggest problem is that
you have to have a the optical equipment on each end that can cover the
entire span for each customer; this gets quite expensive, of course.

2. Build a single run out to the neighborhood / whatever and then have an
actual router / switch split out from there.  This isn't really much more
expensive, but does require a lot more management and more stuff that can
fail.  This is, however, often done for commercial customers in MTUs.
Doesn't really make sense for resi or small business environment.

It costs about the same labor to run anything and the material cost

vary much either.
