Summary

Recommendation ITU-T G.693 provides parameters and values for optical interfaces of single channel intra‑office systems of nominal 10 Gbit/s and 40 Gbit/s aggregate bit rate. Applications are specified with target distances of 0.6 and 2 km and various loss budgets for ITU-T G.652, ITU‑T G.653 and ITU-T G.655 fibres. The latest version makes use of improved specifications for chromatic dispersion of these fibre types.
