 Recommendation G.984 is a family of recommendations that defines gigabit passive optical networks (GPON) for telecommunications access networks. It comprises four recommendations:

• G.984.1, Gigabit-capable Passive Optical Networks (GPON): General characteristics, 2008, with amendment 1.
• G.984.2, GPON: Physical Media Dependent (PMD) layer specification, 2003, with amendment 1 and 2.
• G.984.3, G-PON: Transmission convergence layer specification, 2008, with amendments 1, 2 and erratum 1.
• G.984.4, G-PON: ONT management and control interface (OMCI) specification, 2008, with amendments 1, 2, 3, corrigendum 1, erratum 1 and an implementer's guide.

The GPON OMCI recommendation G.984.4 draws on G.983

G.983

ITU-T Recommendation G.983 is a family of recommendations that defines Broadband Passive Optical Network for telecommunications Access networks. It originally comprised ten recommendations, G.983.1 through G.983.10, but recommendations .6–.10 were withdrawn when their content was...

is a stand-alone OMCI recommendation and supersedes G.984.4 except for G-PON specifics that are not defined in G.988. Future work on the PON management model is expected to appear only in the GPON space.
