There are very survivable fiber cables designed for stage and A/V setups for instance, and even "real" military grade ones. But the common thin LZSH stuff is surprisingly resilient in my experience, so long as it didn't kink the OP would probably have been fine with a "standard" cable. In any case I would always try to place fiber in a place where it can be re-pulled.. conduit, tray, or a plenum.

I bought a big spool of 6 strand Corning stuff a long time ago for various projects, the cost and diameter don't increase much to add some protection lines even if you never imagine using them they can save you a re-pull if you bugger something up in construction.

The contractors were probably dubious of that resiliency given their lack of experience. I recently ran fibre in my house and have to say I was pleasantly surprised that fiber patch cables (unarmored) can survive a good pull through a duct.

They can survive a 500m pull (in 100m stages, or the friction is too high) in mud and rain, through active water line.

Honestly, fibre, even unarmoured with just a standard Kevlar & HDPE sleeve is hardy stuff. When I first started mucking around with it a few years ago I was like “don’t breathe on it too hard”, now I’m like “tie the fibre in a knot on the bullbar and pull it with the truck”.

To be fair, it also got a lot better in the last 20–30 years. In particular, we now have bend-insensitive fiber for the last mile (G.657.A1/G.657.A2) and in general, we just figured out how to make it more robust.

You can kink the shit out of fibre and it’s fine. Like, I’ve accidentally managed ~15mm diameter loops while pulling and then proceeded to yank on them. The Kevlar takes the brunt. Only time I broke a fibre was when it was me and two other guys pulling on it as hard as possible - and instead of moving it went “ping”.
