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. - Ben Cannon, AS15206

Rip it out and run 9/125 SMF fiber home runs. Use BiDi SFPs to re-use your existing (likely SMF thankfully) cable plant. My opinion.
There’s only so much space in conduits, risers and ducts. At some point, scale would press this up against physical infrastructure realities depending on how far the active gear at the head end is from the subscriber.
