Exactly. Dark means that the provider does not see your traffic or manage
the fiber. Dark fiber is hard to acquire these days for that reason; most
telco's want to manage the fiber that they provide at an additional cost.
If they don't manage it they don't make too much of a profit. I have a few
strands in my network. I provide the muxes and light it; the telco just
provides the fiber itself.

When we use this term at my work place, it means we manage the fiber. Dark
fiber = Customer managed.

Blatantly ripped from Newton Telecom Dictionary:
Dark Fiber Unused fiber through which no light in transmitted or installed
fiber optic cable not carrying a signal. Sometimes dark fiber is sold by a
carrier without the (usually) accompanying transmission service. It's
"dark" because it's sold without light communication transmission. The
customer is expected to put his own electronics and signals on the fiber and
make it light.
