Summary

Recommendation ITU-T G.9806 describes a higher speed bidirectional single fibre point-to-point optical access system than the data rate in existing ITU-T point-to-point access systems. It supports 10 Gbit/s for the optical access services including the optical distribution network (ODN) specification, the physical layer specification, services requirements and the operation, administration and maintenance (OAM) specification.

Amendment 1 added support for 25 Gbit/s.

Amendment 2 adds support for 50 Gbit/s.

Corrigendum 1 corrects a typo in Table 7-2.1 by replacing the current Mean launch power MAX Class S "+5.6" value by "−5.6".

Amendment 3 adds support for 100 Gbit/s, optical path loss budget classes S_L (0-10 dB), S_U (5‑15 dB) and B_L (10-20 dB).
