This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
G.992.5 (also referred to as ADSL2+, G.dmt.bis+, and G.adslplus) [1] is an ITU-T standard for asymmetric digital subscriber line (ADSL) broadband Internet access.The standard has a maximum theoretical downstream sync speed of 24 megabits per second (Mbit/s).
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 that are not defined in G.988. Future work on the PON management model is expected to appear only in the GPON ...
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]
Higher Speed PON is the first PON system to use digital signal processing, succeeding both single-channel XGS-PON and multi-channel NG-PON2. [2] It provides upgrade paths for legacy PON generations such as GPON, XG-PON, XGS-PON, and 10G-EPON. [3]
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 ...
Verizon also successfully completed a field trial of the pre-standard XG-PON2 (synchronous 10G-PON) capable of delivering a 10 Gbit/s broadband connection both downstream and upstream. In October 2010, at a Verizon customer's business in Taunton, Mass., the XG-PON2 trial used the same optical fibre that provides that business with its existing ...
For the backhaul of the FTTdp fiber node, the Broadband Forum's FTTdp architecture provides GPON, XG-PON1, EPON, 10G-EPON, point-to-point fiber Ethernet, and bonded VDSL2 as options. [8] [30] G.Fast was used in the UK before the deployment of faster fiber to the premises services. [31]
