How is FTTH different from FTTB?

Question

Computer networks

There are two providers in the house, one provides the service via FTTH, the other via FTTB. How do they differ when installed in an apartment building, because at least one, at least the other, as I understand it, is a switch in the basement / attic and a twisted pair cable to the subscriber's apartment?

Answer 1

On the example of a multi-storey building.
FTTB - optics to the building. most often, an L2 provider switch is placed in the attic and a regular, twisted pair cable goes from it to the apartments. In apartments, an Ethernet router of a provider or client can be installed (not essential) or a wire directly to the computer.
FTTH - optics to the apartment. most often using XPON technology. An optical cable is brought into the apartment, a provider's router is installed (in principle).
In general, FTTX terms are quite specific for the telecommunications industry, and at present they practically do not represent a difference for the end user, but marketers love to call out incomprehensible words and abbreviations, which they themselves often do not understand, but proudly say "Here we have FTTH - it's much cooler than their FTTB"

Answer 2

As follows from the transcript, FTTH - Fiber To The Home and FTTB - Fiber To The Building, in the first case, optics are thrown to the door, in the second - to the building.
