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”.

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.
