How is dark fiber used in a SAN?

I was doing some reading up on SAN technology and I came across the use
of dark fiber to extend SAN connections. My understanding of dark fiber
is that it's unused (dark=no light).
So if it's used in a SAN, it is no longer dark fiber. Am I correct?
Is "dark fiber" required for extending a SAN since it carries no other
type of frame, Ethernet for example?
