  2. G.992.3 Annex J - Wikipedia

    en.wikipedia.org/wiki/G.992.3_Annex_J

    This specification has the same upstream/downstream frequency split of 276 kHz as Annex B, but does not have lower frequency limit of 138 kHz, allowing upstream bandwidth to be increased from 1.8 Mbit/s to 3.5 Mbit/s. This is similar to Annex M, but Annex J can not have POTS on the same line.

  3. G.992.3 - Wikipedia

    en.wikipedia.org/wiki/G.992.3

    ITU G.992.3 is an ITU (International Telecommunication Union) standard, also referred to as ADSL2 or G.dmt.bis.It optionally extends the capability of basic ADSL in data rates to 12 Mbit/s downstream and, depending on Annex version, up to 3.5 Mbit/s upstream (with a mandatory capability of ADSL2 transceivers of 8 Mbit/s downstream and 800 kbit/s upstream).

  4. Radio frequency over glass - Wikipedia

    en.wikipedia.org/wiki/Radio_frequency_over_glass

    More upstream bandwidth; RFoG's improved noise characteristics allow for the use of the full 5–42 MHz return-path spectrum. Additionally, higher-performance RFoG systems not only support DOCSIS 3.0 with bonding, but also enable 64 quadrature amplitude modulation (QAM) upstream transmission in a DOCSIS 3.0 bonded channel, dramatically ...

  5. G.992.5 - Wikipedia

    en.wikipedia.org/wiki/G.992.5

    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).

  6. IMT Advanced - Wikipedia

    en.wikipedia.org/wiki/IMT_Advanced

    IMT-Advanced is intended to accommodate the quality of service (QoS) and rate requirements set by further development of existing applications like mobile broadband access, Multimedia Messaging Service (MMS), video chat, mobile TV, but also new services like high-definition television (HDTV). 4G may allow roaming with wireless local area ...

  7. List of interface bit rates - Wikipedia

    en.wikipedia.org/wiki/List_of_interface_bit_rates

    Choosing service providers or interfaces based on theoretical maxima is unwise, especially for commercial needs. A good example is large scale data centers, which should be more concerned with price per port to support the interface, wattage and heat considerations, and total cost of the solution.

  8. 10G-PON - Wikipedia

    en.wikipedia.org/wiki/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 ...

  9. Digital subscriber line - Wikipedia

    en.wikipedia.org/wiki/Digital_subscriber_line

    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.
