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.

Verizon has no problem delivering service via fiber with a DSX-1 or Ethernet handoff.  We simply want that service backhauled to us just like all our customers with service over copper with DSX-1 or Ethernet handoff.
