G.984.6 : Reach extension (2008), with amendments 1 (2009) and 2 (2012) [12] G.984.7 : Long reach (2010) [13] 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 GPON specifics ...
GPON networks have now been deployed in numerous networks across the globe, and the trends indicate higher growth in GPON than other PON technologies. G.987 defined 10G-PON in 2010 [15] with 10 Gbit/s downstream and 2.5 Gbit/s upstream – framing is "G-PON like" and designed to coexist with GPON devices on the same network. [16]
ADSL initially existed in two versions (similar to VDSL), namely CAP and DMT. CAP was the de facto standard for ADSL deployments up until 1996, deployed in 90 percent of ADSL installations at the time. However, DMT was chosen for the first ITU-T ADSL standards, G.992.1 and G.992.2 (also called G.dmt and G.lite respectively). Therefore, all ...

[1] 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 ...
G.fast is a digital subscriber line (DSL) protocol standard for local loops shorter than 500 meters, with performance targets between 100 Mbit/s and 1 Gbit/s, depending on loop length. [1] High speeds are only achieved over very short loops.
There were roughly 0.6 billion fixed broadband subscribers and almost 1.2 billion mobile broadband subscribers in 2011. [139] In developed countries people frequently use both fixed and mobile broadband networks. In developing countries mobile broadband is often the only access method available. [93]
