Broadband and Wi-Fi Technologies
VDSL/ADSL – DSL, which stands for Digital Subscriber Line, is a technology that delivers broadband speeds over distances of miles or kilometers via copper wiring. DSL delivers broadband to more people today than any other technology. Roughly two-thirds of all broadband subscribers are DSL subscribers, and there are more new DSL subscribers each month than new subscribers for all other broadband access technologies combined.
Vectored VDSL2 (Vectoring) – Vectoring greatly improves the performance of VDSL2 by using physical layer signal processing to enable cancellation of crosstalk between all the lines that terminate on a single DSLAM.
G.fast – G.fast aims at providing ultra-high speeds over copper twisted pairs, up to and sometimes even exceeding speeds of 1 Gbps.
G.now – G.now is a MARVELL brand for a broadband access platform based on the G.hn technology. G.hn is a family of ITU-T Recommendations (G.996x) defining home networking over phone lines, power lines and coaxial cables.
Hybrid Fiber Coax (HFC) – In a hybrid fiber coaxial (HFC) network, optical fiber and coaxial cables are used in together but in different parts of the network to carry broadband data.
Fiber-to-the-Home (FTTH) – Gigabit-capable Passive Optical Network (GPON) extends fiber all the way to the home or premises, and uses an entirely passive outside plant (with the exception of Optical Network Terminals, ONTs, that are sometimes located outside of homes).
Terabit DSL (TDSL) – Fiber-like speeds of 10 – 1000’s of gigabits/second (Gbps) are possible by using the previously unexploited waveguide modes of current copper infrastructure. Waveguide-mode use is similar to use of millimeter-wave transmissions in advanced wireless and 5G. Waveguides can enable use of frequencies above 100 GHz for extraordinary speeds.
