10G-PON
technology for computer networking
10G-PON (also known as XG-PON or G.987) is a 2010 computer networking standard for data links, capable of delivering shared Internet access rates up to 10 Gbit/s (gigabits per second) over optical fibre. This is the ITU-T's next-generation standard following on from GPON or gigabit-capable PON. Optical fibre is shared by many subscribers in a network known as FTTx in a way that centralises most of the telecommunications equipment, often displacing copper phone lines that connect premises to the phone exchange. Passive optical network (PON) architecture has become a cost-effective way to meet performance demands in access networks, and sometimes also in large optical local networks for fibre-to-the-desk.
Passive optical networks are used for the fibre-to-the-home or fibre-to-the-premises last mile with splitters that connect each central transmitter to many subscribers. The 10 Gbit/s shared capacity is the downstream speed broadcast to all users connected to the same PON, and the 2.5 Gbit/s upstream speed uses multiplexing techniques to prevent data frames from interfering with each other. Each user has a network device that converts between the optical signals and the signals used in building wiring, such as Ethernet and wired analogue plain old telephone service. XGS-PON is a related technology that can deliver upstream and downstream (symmetrical) speeds of up to 10 Gbit/s (gigabits per second), first approved in 2016 as G.9807.1. XGS-PON uses time division multiplexing (TDM) and time division multiple access (TDMA).
Standards
ITU-T G.987 is the standard for 10G-PON.
Asymmetric 10G-PON is specified as XG-PON1: 10 Gbit/s downstream and 2.5 Gbit/s upstream (nominal line rate of 9.95328 Gbit/s downstream and 2.48832 Gbit/s upstream).
Symmetric 10G-PON is also proposed as XG-PON2 with 10 Gbit/s upstream, but would require more expensive burst-mode lasers on optical network terminals (ONTs) to deliver the upstream transmission speed.
The public source identifies “10G-PON” as technology for computer networking. This brief keeps that definition visible, then builds a research path around 10G-PON, technology and computer.
Why this record matters
A short description can identify a subject without explaining its stakes. For “10G-PON”, the useful work is to connect “technology for computer networking” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 9, 2026. The linked authority identifier is Q3642817. 1 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2010 and 2016.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
