We connect via FTTB. What do providers use to convert optics to copper?

Question

network hardware

Hello.
Here, for example, optics from a provider flies into the building of a small shopping center. What's next? How is an optical signal converted to electrical? Special switch? Inverter? How? How?
Thanks in advance.)

Answer 1

Usually, in theory, if FTTB is usually in the attic, there is a cabinet with an L2 switch (they overwhelmingly have 2 SFPs for such a thing) into which optics (or a beam of a star or an arc of a ring, or whatever else the provider has screwed up) enters and from it is already in apartments/offices the usual twisted pair goes down on routers of clients.
In principle, individuals can also throw uplink from home via xPON, in which case optics->terminal (sfp or RJ45)->L2-switch->client router

Answer 2

media converter.
Well, or a router where you can cut the optics, and the output is copper. It has the same M.

Answer 3

You won’t believe it - with a router :) In a rather ordinary Mikrotik RB4011, there is an SFP port into which the corresponding module is plugged (preferably also Mikrotik, or SNR at worst, but not GigaLink!), into which optics come. And that's it :) In Mikrotik - port, the port has settings :)
