Fibre to the premesis. For a large building, the fibre terminates in the basement and further distribution is with ethernet.

(But see also the first paragraph of the article.)

G.fast is common in older blocks where rewiring with ethernet or fiber isn't feasible.

Others have given the technical differences.

The practical differences are that FTTP is normally fibre provided by openreach. Openreach being the dominant heavily regulated monopoly. They provide the link, and ISPs resell over the top.

FTTH is normally fibre provided by the same company as the ISP, and so has a much smaller area of coverage.

No: FTTP and FTTH are the same thing. It’s just that in the case of FTTH the Premises in FTT”P” is a Home. It’s a colloquial difference and doesn’t represent any difference in technology or provision.

Perhaps I should have been clearer, FTTP is what openreach calls running a fibre to your house, FTTH is what most over companies call it.

As others have said, it just distinguishes between "Premises" and "Home". They're the same. They differ from FTTN (Node) or in the UK apparently FTTC (Cabinet) which is one of the boxes outside "near" your home or office, much like DSL works.

They're not (always) the same, a distinction can be drawn in the case if blocks of flats (and perhaps terraces, especially where council/mgmt company managed?) whereby FTTP means it's fibre to the block and copper to the flats. FTTH in such cases would afaik be pretty unusual, but hypothetically would mean that each flat has it own fibre termination.

FTTP aka FTTB (Building). The nomenclature's all a bit ridiculous IMO.

Fibre to the premises, the same as FTTH

Fiber to the pole.

It's copper from the telephone pole to your home. It's cheaper to implement and gives you less overprovisioning.

Fiber To The Premises. Meaning the fibre optic cable comes right to your home as opposed to FTTC Fibre To The Cabinet which means only as far as the telephone cabinet and then copper to you. It is unfortunate that fibre has been used so widely as a marketing term it's now often nearly impossible to tell what technology is actually being advertised.

No, this is Fibre to the Premises, IE actual fibre all the way to your house.

No, that's FTTC (Fiber to the Curb)

Fibre to the Cabinet, in the UK
