I'ts almost certainly shared. 99% of FTTH is (X)G(S)-PON which shares the fibre over a few properties. Usually something like 32 max.

The Swiss use point to point fibre (there are a few small pockets of this elsewhere). But in reality it is very hard to saturate. XGSPON has 10G/10G shared between the node. GPON has 2.4gbit down/1.2gbit up shared across the node.

In reality point to point is not really a benefit in 99.99% of scenarios, residential internet use cannot saturate 10G/10G for long, even with many 'heavy' internet users (most users can't really get more than >1gig internally over WiFi to start with).

And if it is a problem there is now 50G-PON which can run side by side, so you just add more bandwidth that way.

Sweden doesn't use much PON either. If a countries fiber build out started before gpon was released or got popular you likely continue a lot with point to point. There's a small drawback, TDM/A for the uplink, introduces some jitter but guessing it's not as bad as cable.

Residential 2.5gb equipment is just starting to appear as a “default” and 10gb is still pretty rare, though accessible if you want it.

I don’t even have 25gb and I’ve a home lab!
