ABSTRACT:
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.
