havn't heard that its a special type of fiber, just a condition of the
fiber.

Dark fiber means you push the light and is currently unused. Don't worry, I
was in the dark when the term was introduced to me. :-)

Think for a minute. How does fiber transmit data? Using light. So when the
provider is selling "dark fiber" it means that it's fiber without the light
source to transmit the data. You provide your own. Generally get it at a
discount but in practice it ends up costing about the same since the cost
David is correct. Dark fiber is unprovisioned by the
carrier and is useful for campus and MAN
installations. For example, I can order dark fiber
between buildings in the same city (under 70 miles)
and run whatever services I wish (DWDM, GE, etc).
