G.984.1 – Gigabit-capable Passive Optical Networks (G-PON): General characteristics

I n t e r n a t i o n a l Te l e c o m m u n i c a t i o n U n i o n

Provides examples of services, User Network Interfaces (UNI) and Service Node Interfaces (SNI) that are required by network operators. In addition, it shows the principal deployment configuration. Wherever possible, this Recommendation maintains characteristics from the ITU-T G.982 and G.983.x series Recommendations in order to promote backward compatibility with existing Optical Distribution Networks (ODN) that comply with these Recommendations.
G.984.2 – Gigabit-capable Passive Optical Networks (G-PON): Physical Media Dependent (PMD) layer specification

G.984.6 – Gigabit-capable Passive Optical Networks (G-PON): Reach extension

Outlines the architecture and interface parameters for G-PON systems with extended reach using a physical layer reach extension device, including regenerators or optical amplifiers. The maximum physical reach is up to 60 km, with loss budgets in excess of 27.5 dB being achievable in both spans. This new capability will allow operators to provide optical access service to areas that were previously out of reach, and also explore new network designs for greater central office consolidation.

Specifies the physical layer requirements and specifications for the Physical Media Dependent (PMD) layer. This Recommendation covers systems with nominal line rates of 2488.320 Mbit/s in the downstream direction and 1244.160 Mbit/s and 2488.320 Mbit/s in the upstream direction. Both symmetrical and asymmetrical (upstream/downstream) Gigabit-capable Passive Optical Network (G-PON) systems are described.
G.984.3 – Gigabit-capable Passive Optical Networks (G-PON): Transmission convergence layer specification

G-PON means
• Full service support – including voice, TDM, Ethernet (10/100/1000 BaseT), xDSL, leased lines, wireless
