ITU-T Recommendation G.984 is a family of recommendations that defines gigabit passive optical network (GPON) 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.
G.987 XG-PON
ITU-T Recommendation G.987 is a family of recommendations that defines 10 gigabit passive optical network (XG-PON) telecommunications access networks. It comprises four recommendations:
- G.987, 10-Gigabit-capable passive optical network (XG-PON) systems: Definitions, Abbreviations, and Acronyms, 2010.
- G.987.1, XG-PON: General requirements, 2010.
- G.987.2, XG-PON: Physical media dependent (PMD) layer specification, 2010.
- G.987.3, XG-PON: Transmission convergence (TC) specifications, 2010.
G.988 OMCI
ITU-T Recommendation G.988 defines a management and control interface for optical network units. It comprises one recommendation:
- G.988, ONU management and control interface (OMCI) specification, 2010.
