An optical fiber cable including first, second and third optical fibers
connected together so that light traveling through the cable travels
through the first optical fiber, then through the second optical fiber
and then through the third optical fiber. The second optical fiber has a
negative dispersion value. The first and third optical fibers each have a
positive dispersion value. The cable optically connects together two
optical repeater stations, or an optical repeater station and an end
station. Lengths of the first, second and third optical fibers are set so
that loss in the first, second and third optical fibers of light
transmitted through the first, second and third optical fibers is
compensated by Raman amplification occurring in the first, second and
third optical fibers.
