Yeah, I suppose you've got one or two 250um fibers inside of a 3000um
buffer tube and that's a fair bit of extra space. Plus the grease in
the tube ought to distribute pressure around.
....just not aimin to have any problems.

I would hazard that loose tube is pretty immune from freezing water
crushing damage in a duct.

In this case it was a round loose tube drop cable.

Subject: [AFMUG] fiber conduit depth
So we buried a 3/4 PVC conduit about 8" deep for a drop cable. Due to
obstacles, that's as deep as it was realistically going to go. Now
somebody is wondering whether ice in the conduit is going to be a
problem. We're assuming in the long run water will always get in, but
the question is whether it'll hurt the fiber when it freezes.
The person doing the wondering speculates that when the ice expands it
will crush the cable and damage the fibers. Is this actually
possible?
