Just patched a long fiber link, which would've absolutely _sucked_ to get CAT.7 cable through.
The steel-armored OS2 cable is cheap and super robust/easy to work with. The LC connectors are even smaller than the hole for CAT.7 would've been.

This is nice \o/

What I want to say is: Don't be afraid of fiber for DIY networking people, it's awesome and often muuuch better than copper cable!

I also didn't have to do any annoying LSA+ terminations or crimps and the link will do 10G+ easily :)
