This Recommendation describes a single-mode fibre with chromatic dispersion that is greater than some non-zero value throughout the wavelength range of 1460-1625 nm. This dispersion reduces the growth of non-linear effects that can be particularly deleterious in dense wavelength division multiplexing (DWDM) systems. This fibre usesnon-zero dispersion to reduce four-wave mixing and cross-phase modulation over a wider wavelength range than the fibre described in [b-ITU-T G.655]. Extensions are possible, in the future, to wavelengths beyond the 1460-1625 nm region (to be determined).
