Nope, that’s HFC, and while it’s radio-frequencies just like DSL, it’s a shared medium across the entire neighbourhood while DSL is dedicated.
Ah then in that case you might want to add that some people have FTTC DOCSIS which is actually pretty good, 300Mbit down etc

Assuming they're the same as my home, they come with a battery backup unit which powers the landlines (as landline phones are normally powered from the exchange - and thus work in power cuts) Of course people who still have landlines nowdays probably have cordless ones that require a powered base station, but I assume that at least in the UK, the line must be left powered during power cuts.
Nope, none of that in France - just a standard fibre socket, and the ISP gives you an ONT that turns it into Ethernet, which then goes into a router. I've never actually seen any ISP there even advertise a battery backup unit, I guess if you need they'll just tell you to buy a standard UPS. No idea how it works in the UK, haven't had consumer-grade fibre here yet, always just got business-grade stuff where you bring…
I've installed (business) fibre links on 6 continents, handoff has always been a pair of fibres (usually LC or SC), usually with a /30 ipv4/ethernet, and a routed network pointing at my end of the handoff (or in the case of private peering, a BGP configuration)
My FTTH from BT is a single fibre (no idea if it's compatible with generic bidirectional sfps). This runs into an Openreach converter box - powered by a battery backup - which has 2 phone outputs and 4 rj45s.
My core mikrotik plugs into one of the rj45s and establishes a pppoe session with BT's network.
