What is xDSL technology?

xDSL is a technology which enables ordinary voice-grade copper telephone wires, used to service more than 600 million customers worldwide, to also carry high-speed data traffic at the same time, thus obviating the need for expensive system upgrades.

What does xDSL stand for?

Digital Subscriber Lines
Services. Digital Subscriber Lines (xDSL) xDSL, a term that encompasses the broad range of digital subscriber line (DSL) service options, has the potential to revolutionize the areas of Internet access and telecommuting by offering a low-cost, high-speed data transport option for both individuals and businesses.

What technology does DSL use?

The underlying technology of transport across DSL facilities uses modulation of high-frequency carrier waves, an analog signal transmission. A DSL circuit terminates at each end in a modem which modulates patterns of bits into certain high-frequency impulses for transmission to the opposing modem.

What is VDSL technology?

Very high-speed digital subscriber line (VDSL) and very high-speed digital subscriber line 2 (VDSL2) 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.


xDSL is a general term for various types of digital subscriber line (DSL), including ADSL, RADSL, VDSL, SDSL, IDSL, and HDSL.

What’s the difference between VDSL and ADSL?

ADSL provides a connection of up to 24 Mbps. VDSL (Very high bit rate digital subscriber line) is a newer technology. Like ADSL, VDSL uses your copper phone line, but delivers a faster connection speed. A VDSL connection is approximately twice as fast as ADSL.

What is the difference between DSL and fiber?

It’s simple — fiber is fast. While DSL uses copper phone lines to transmit data, fiber uses ultra-thin glass strands that carry light instead of electricity. Since light can travel very quickly through the fiber-optic cables, fiber connection can see gigabit speeds 100x faster than DSL.

What is the latest DSL technology?

VDSL. VDSL (Very high data rate DSL) is a developing technology that promises much higher data rates over relatively short distances (between 51 and 55 Mbps over lines up to 1,000 feet or 300 meters in length). It’s envisioned that VDSL may emerge somewhat after ADSL is widely deployed and co-exist with it.

What are types of DSL?


  • HDSL (High-Bit-Rate DSL)
  • SDSL (Symmetric DSL)
  • ADSL: Asymmetric DSL.
  • SHDSL: Single-Pair, High-Speed Digital Subscriber Line.
  • VDSL: Very-High-Bit-Rate DSL.
  • VDSL2: Very-High-Bit-Rate DSL 2.

Is VDSL same as fiber?

VDSL (Very High Speed Digital Subscriber Line) is the best known yet, but basically only partially fiber-optic based. In this variant, fiber optic cables are laid from the switchboard to the cable distribution system (DSLAM).

Is VDSL better than fibre?

With speeds of 100MBps and up, ultra fast fibre broadband is more reliable and faster than average broadband speeds for ADSL or VDSL. Unlike the copper based network, fibre is not distance sensitive, so there are no connection interruptions or dropping speeds.

Is VDSL better than Fibre?

¿Qué es la tecnología xDSL?

DSL ha dado origen a una familia de equipos y soluciones de transmisión que se agrupan bajo el nombre de tecnologías xDSL las cuales soportan servicios de gran ancho de banda sobre la red telefónica de cobre ya existente. 3 ¿Por qué la x?

¿Qué son los servicios basados en xDSL?

Los servicios basados en xDSL se han establecido como una solución para el acceso de banda ancha a datos, tanto en los mercados comerciales como residenciales. Las principales ventajas de esta tecnología son la capacidad para acomodar al mismo tiempo voz y datos y la posibilidad de aprovechar la infraestructura ya existente de telecomunicaciones.

¿Qué es la tecnología HDSL?

High-data-rate Digital Suscriber Line (HDSL).- Es un tipo de tecnología xDSL simétrica, es decir, provee el mismo ancho de banda en los dos sentidos.

¿Cuáles son las variantes de xDSL?

Son múltiples las variantes de xDSL, entre otras: HDSL, SDSL, ADSL, VDSL y la estandarizada hace apenas algunos meses por la UIT, GSDSL. Seguidamente relacionamos las variantes mas significativas:
