Community fibre customer here!
I’d upload pictures but the site’s size restrictions are bound to make it an impossibility…
Community fibre use a slim (~2.5mm) drop cable that is a single piece all the way to the termination plate, which is internally mounted. The plate has a pre-installed connector which is fusion spliced to the drop cable. This termination plate then connects to the ONT.
On the outside of the house, a small auto-tensioning fixture is mounted to the eyelet that is mounted to the soffit/wall. As you probably guessed, this maintains tension on the drop wire to the poll.
That’s about it. I had no problems asking the installer to take a preferred route and had them pull it through conduit, so the cable entered my under-stairs cupboard, where the ONT and pfSense router are located.
