They installed fibre optic Internet in my neighbourhood a while back, and this is what the cable ducts look like. Also interesting to see how these get installed, with a sort of huge needle/drill on tracks.

I’m sure it’s how they find specific cables if they need to do a repair.
was at a facility that was installing a network for a new build out- I don't know how many cables were pulled, but they were pulling them twenty at a time, and the final bundle going to the network switching room was... uh... about the size of an enclosed slide in diameter...
... the guy at the box side, whose job was to label and cut was only doing the pull-side labels. They ended up loosing about two weeks on that project.
