Quite popular in the UK is the concept of A) Splitter cabinets which you get a fibre back to and then get put on one of several splitters. These cabs are completely passive and come in 48 or 96 (maximum) ports (usually fed by 12f back to the exchange). You can then patch a user onto a different splitter or even a dedicated fibre back to the exchange for P2P ethernet. B) Split at 8:1 near to the end user and then split again at the exchange, sometimes upto 8:1 again, so 1:64 on XGS-PON. The advantage of this is as a PON gets busy it's a 10 second job to change it to 2 X 4:1 splits in the exchange and so on all the way down to having upto 8 subscribers on a port. If you have a business park you can make a central decision to not further split at the exchange so they get 8:1, and you don't have to change your physical plant at all, so the field engineers build to one standard regardless of if it's domestic or business.
