Summary:
|
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 ITU‑T G.65x‑series 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.
