Re: A few GPON questions...

Sure but I can fit quite a lot of fiber in very little space. eg an 864 is approx 1” dia.

Fan-outs can be done each floor, etc.  And a single single mode strand has prodigious bandwidth available with the 
right optics.

Bonus: if you did this 30 years ago, you’re still good.  Anything else (remember FDDI grade Multi-mode?) is not future 
proof IMO.  Basic 9/125 Singlemode always will be.

In city wide deployments, a bit different, especially for eg residential service at economical pricing.  GPON for sure 
has it’s place, I just don’t personally feel it’s inside a building all else being equal.
