A) I've never seen fiber without wire for the locaters to use later.

B) Fiber duct is often punched through with a ram, not buried
by cut & cover methods; it being far cheaper to ram. But b1)
that means there is no way to leave "buried trouble below" tape
and b2) the NEXT guy will likely be ramming as well so even if
there was tape, no one would see it.

Note the ram is a source of many problems. The protypical is 
the cas company uses one to install a new plastic line to a house,
inadventently going clean through a 6" sewer line. Trees soon
clog the sewer with roots, and a sewer company roto-rooters
[tm] the line clear, flooding the sewer system and basement with
gas. Kaboom.
