Re: what is dark fiber?

[Karen . Young]

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
of management shifts to you. From what I hear, its easier and cheaper in
the long run to just go with standard fiber. However, it also means that
you're at the mercy of the provider for service (of course you are
anyway...)

hi.
what is dark fiber?
i found some sites that says dark fiber means unused fiber.
is it so?
i think dark fiber must be different then unused fiber.
i mean for example. 10gigabit ethernet runs on dark fiber.
dark must be something related to bandwidth or wavelength.

if someone knows dark fiber definition i ll be happy.
