Dark fiber might be one of those terms that is used differently from place
to place. But when I used to splice fiber for a LEC, we referred to dark
fiber as unused and more importantly unusable. The engineering group would
send us the prints and assign the fibers that they wanted us to splice.
There would be fiber splices moving the light from point "a" to point "b".
In the process of moving from one cable run to another, we would end up with
fiber that was "dark" or unusable because they had been cut and had no way
of terminating back to one of the central offices.

It is my understanding that dark fiber is un-used/non-saturated fiber. I
havn't heard that its a special type of fiber, just a condition of the
fiber.
