Do those small utility boxes alongside the tracks make sense for fiber optic? I expected things like that to be larger, if only because fiber has a minimum bend radius.

Edit: Good article though, I enjoyed it a lot.

The min bend radius isn’t that large in my experience. On the order of 10cm IIRC, possibly even less.

Even less is correct: outdoor fibers (G.652.D) have a minimum bend radius of about 30mm. The indoor counterpart (G.657.A1 and A2) have 10mm and 7.5mm.

		Those are more of a technically no? Like I have fiber to the house and you really need to pinch it and whatnot to cause an internet outage.

Much smaller than that, some might even say a utility box is overkill: https://old.reddit.com/r/techsupportgore/comments/nvwcuh/the...

Fiber’s perfectly happy being joined in 12” by 16” boxes for small runs. The terminal box in my garage has a few loops and is more like 6” x 8”.
