ITU-T 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.983.2, which defines the BPON management model. However, G.984.4 removed all references to ATM. G.988 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.
