Hi,

The draft is here : https://wiki.openstreetmap.org/wiki/Proposed_features/Telecom_local_loop Still need edits but ready for comments,

You can find here an exemple of a street cabinet for fiber : http://www.openstreetmap.org/node/3561128729 . For central offices, i mapped some ones for copper but we can use the “telecom:medium=fiber” tag to define those used for fiber : http://www.openstreetmap.org/way/240639175
