You're not trying to educate anyone at all. You're just stomping your foot
and insisting that you're right rather than have a meaningful discussion.

I did some research on what NTT has done on fiber deployment. From what
I've seen, they split things up into feeder, distribution and drop cable,
with the splitter between feeder and distribution. Amazingly enough, that's
what we do as well. Feeder to splitter, then on down the street breaking
off at strategic splice cases where drops go to houses. The only difference
between that and our active infrastructure is the presence of the splitter.

We also do single-stage 32:1 splits. If we ran each drop cable from the
splitter all the way to the house, we would have extremely long drop
cables, and lots of them all bundled together going down the street. We
don't do that, we use mainline distribution cable like I described above.

The last thing I feel that I need to point out is that what works in one
type of area doesn't necessarily work in another. Fiber deployment in a
large urban area is a completely different animal than in a 40-50K
population town in the midwest USA.
