Summary - G Suppl. 47 (03/2025) - General aspects of optical fibres and cables

Supplement 47 to ITU-T G-series Recommendations provides information on the general transmission characteristics of single-mode optical fibres and cables specified in the ITUT G.65xseries of Recommendations related to the practical use condition. It covers the environmental and length-related characteristic of ITU-T G.65x-series optical fibres and cables. The fibre material-related characteristics are also described in Appendix I.
Version 3 of this Supplement provides general guidelines for estimating the wavelength dependence of the attenuation coefficient and chromatic dispersion.
