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.

How many fiber cables do they put in each one of those ducts? There’s 15 ducts and let’s say 5 cables each, 75 fiber lines is a ton of bandwidth!! Lots of room for expansion there.
I did this for work a few years ago in New Zealand and they run them through neighbourhoods with enough for each house and spare ones for errors and expansion. Particularly in commercial areas because some businesses need multiple lines.
The fibre itself is a piece of glass the size of a strand of hair with infrared shot down it, but with the casing it looks similar to that small blue one poking out there. Can’t remember exactly how many but that’s the size of a single line so you can fit a lot of them.
When they installed it to my house, they left some of the bare fibre lying on the ground. It's a little thicker than the fibre you see in those "fibre optic flower lamps", but not by much. If I'm not mistaken, the blue wire you see in the picture is to help detect the cable after it's buried.
Good catch, that’s exactly what that is. Just to clarify my Job was to take it from the boundary of the property and finish the connection so I’m not super knowledgeable on those main lines but the fibre shot through them to us was about the size of that blue wire. There’s also a type that goes along phone lines instead of underground and that’s a thick black one with Kevlar in it.
