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 added support for 50 Gbit/s.

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

Amendment 3 added 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).

Corrigendum 2 made the following additions and corrections:

1)��������� Added a keyword for 100 Gbit/s

2)��������� Added a missing definition for Overload in clause 3

3)��������� Replaced MAX/max with Maximum and MIN/min with Minimum as needed

4)��������� Corrects the following typos:

������������ Table 7-1.3

����� Correct Nominal modulation rate unit to "Gbaud"

����� Add "�" as the unit for modulation format and bit error ratio

����� Add missing unit "dBm" for Launch power in OMAouter minus TDECQ and Average launch power of OFF transmitter

����� Correct mean launch power Minimum for 1.4 dB ≤ TDECQ < 3.2 dB to "−1.8 + TDECQ" for Class S and "6.2 + TDECQ" for Class B�

����� Correct receiver Sensitivity for 1.4 dB ≤ TDECQ < 3.2 dB to "−17.3 + TDECQ" for both Class S and Class B�

������������ Table 7-1.4

����� Correct nominal modulation rate unit to "Gbaud"

����� Add the missing unit for |TDECQ � TECQ| (Maximum): "dB"

����� Add "�" for the unit of modulation format and bit error ratio
