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]
A gateway is commonly used to make an ADSL connection. Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide.
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.
Following the publication of 40 Gbps NG-PON2 in July 2015, standardization activities turned to higher speed PON. [4] In November 2016, the Full Service Access Network (FSAN) Group released the Standards Roadmap 2.0 which indicated the development of "future optical access systems" with peak transmission rates above 10 Gbps.
ITU-T Recommendation G.983 is a family of recommendations that defines broadband passive optical network (BPON) for telecommunications Access networks.It originally comprised ten recommendations, G.983.1 through G.983.10, but recommendations .6–.10 were withdrawn when their content was incorporated into G.983.2.
Very high-speed digital subscriber line (VDSL) [1] and very high-speed digital subscriber line 2 (VDSL2) [2] are digital subscriber line (DSL) technologies providing data transmission faster than the earlier standards of asymmetric digital subscriber line (ADSL) G.992.1, G.992.3 (ADSL2) and G.992.5 (ADSL2+).
Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. [1] In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access.
