Non-zero dispersion fiber with improved characteristics for wideband optical transmission

In this paper, we propose a non-zero dispersion fiber for wideband optical transmission. The proposed fiber has large enough effective area and small macrobanding loss (in accordance with the draft of ITU Recommendation G.656). The fundamental part of the intensity is focused in a central part of the core, that is in a place with rather small percentage of the doping material additive allowing us to achieve low attenuation in the fiber. The chromatic dispersion dependence of wavelength is chosen so the fiber can be used in S, C and L wavelength diapasons. For long-haul and wideband optical networks, advanced technologies can be applied to increase overall system margin. As the percentage of data traffic in a network continues to increase, the emphasis on ultra-long-haul transport will also increase.
