Hello,
as far as I understood from the ISP's the "dark fiber" is the equivalent of
a leased line:
the ISP provides you the Physical connectivity between the endpoints, but
they do not provide any routing
This kind of commercial offer is mainly used by ISPs that use DWDM on their
fibers and they can offer one wavelength to you.
