I don't you want your fibre getting smashed by magnets all day :P

There is a lot of fiber running in railroad right of way.

Southern Pacific Railroad Internal Network Telecommunications, or SPRINT. The telecommunications name survives. The railroad is now part of Union Pacific.

I suspect that the folks putting fiber in railroad right of way know how to avoid crushing failure.

How is an _optical fiber_ affected by _magnets_ ?

When it gets crushed by the passing bolts of magnets which consume the entire tube diameter because they are propelled by air and need to fill the entire tube in order to work.

If you want to run fibre along, and it's a good idea while you're digging away, do it in a parallel but separate tube.

I think that was the idea of the parent comment, just put anything else in the hole in the ground. Fiber is welcome :)
