It sounds like your service provider is providing some form of metro-E solution or DWDM based solution.

What sort of configuration are they expecting at the handoff point ?

you know , we only have a single 2 core fiber and we should connect 20 node to eachother as a ring topology, it means a fiber must enter the switch and exit from the same switch, is it possible for switch to  drop-and-insert fiber optic or not ?

Its possible. It does sound like a DWDM solution. You should press your provider for more details.
