I agree, but what if it's not as simple as a bunch of strands in a
conduit.  What if the plant is part of some sort of multiplexed network or
GPON solution.  That's alot harder to share with another carrier .  But yes
if it's simple stands of glass not plugged into anything in particular it
can be shared just like copper.  Alot of the fiber plant out there isn't
used this way though.

This is different than sharing cables. Any long distance carrier is still
free to purchase service from any LEC.  The term "sharing fiber" seemed to
imply that it's freely transferable from one company to the next.  It
largely isn't though, which is why I think the FCC hasn't touched it yet.
