ITU-T Recommendation G.983 is a family of recommendations that defines
broadband
In telecommunications, broadband or high speed is the wide-bandwidth (signal processing), bandwidth data transmission that exploits signals at a wide spread of frequencies or several different simultaneous frequencies, and is used in fast Inter ...
passive optical network
A passive optical network (PON) is a fiber-optic telecommunications network that uses only ''unpowered'' devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the '' last mile'' between Internet ...

telecommunications
Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies. These means of ...
Access networks. It originally comprised ten recommendations, G.983.1 through G.983.10, but recommendations .6–.10 were withdrawn when their content was incorporated into G.983.2.
The current view is that the BPON standards are mature, and no further work will be done on them after the 2007 round. The

OMCI definition has been revised to stand alone, rather than citing G.983.2.
Although G.983 is directed at BPON, the GPON recommendations draw heavily on it, especially

Current recommendations
The current recommendations are:
G.983.1 Broadband optical access systems based on passive optical networks (PON), 2005, with amendment 1 and erratum 1. Includes the definition of the
churning cipher.
G.983.2 ONT management and control interface specification for B-PON, 2005, with amendments 1 and 2, erratum 1 and an implementer's guide.
G.983.3 A broadband optical access system with increased service capability by wavelength allocation, 2001, with amendments 1 and 2.
G.983.4 A broadband optical access system with increased service capability using dynamic bandwidth assignment, 2001, with amendment 1 and corrigendum 1.
G.983.5 A broadband optical access system with enhanced survivability, 2002.
