Abstract: PROBLEM TO BE SOLVED: To harmonize the necessity of high power density for increasing Raman amplifier efficiency with that of low power density for reducing nonlinear operation in an optical transmission system. SOLUTION: The optical cable is characterized in that it has one or more single mode optical fibers of a first type and one or more optical fibers of a second type, that both types of optical fibers are suitable for transmitting optical signals at a system wavelength λs, and that the effective cross section of the first type optical fiber is substantially larger than that of the second type. In such a cable structure, it is desirable that the optical fiber of the large effective cross section (i.e., Aeff>=70 μm2) and that of the small effective cross section (i.e., Aeff<=60 μm2) are contained in the same numbers in the same cable. In addition, a variety of cable structure can contain, for example, a planar array of optical fibers bound together by a matrix material and a fiber group enclosed within one or more plastic tubes.
