A1, Austrian subsidiary of Telekom Austria Group, test Bell Labs G.fast vectoring technology, delivering speeds faster than 1 Gbps and demonstrating potential for copper in next-generation broadband access
PARIS, July 2, 2013 /PRNewswire/ -- Alcatel-Lucent (Euronext Paris and NYSE: ALU) and A1, the Austrian subsidiary of Telekom Austria Group, have conducted the world's first trial of an innovation from Alcatel-Lucent's Bell Labs that can upgrade existing copper telecommunications networks into ultra-fast broadband access systems capable of delivering video, data and information at speeds of more than 1 gigabit per second (Gbps).
With Alcatel-Lucent repositioning itself as a specialist in IP Networking and Ultra-broadband access, the company has adapted Bell Labs vectoring techniques - already in widespread commercial deployment in VDSL2 networks - to work with a new transmission technology called G.fast, which use a wide frequency band to achieve very high speeds on copper lines over very short distances.
G.fast is intended for typical applications of 500 megabits per second (Mbps) speeds at 100 meters or less. In recent demonstrations and under laboratory conditions, Alcatel-Lucent achieved 1.3 Gbps over 70 meters, making G.fast a promising option for service providers to complement their fiber deployments.
In any fiber-to-the-home project, a substantial part of the cost-per-subscriber is in the last few meters between the nearest network cabinet and the home. These costs can be avoided by using G.fast over the existing copper telephone line, rather than having to dig up roads or private property to install new fiber.
Bell Labs vectoring technology addresses one of the challenges related to the deployment of G.fast. In many real-world applications, such as fiber-to-the-building, the copper lines serving neighboring homes are packed closely together: this results in crosstalk interference between lines, which significantly reduces the potential speed of data transmission. G.fast vectoring removes this crosstalk, stabilizes the transmission quality and enables the technology to perform to its full potential.
- The trial, conducted with A1 and using a Bell Labs prototype, first tested G.fast over a single, good quality cable, achieving a maximum speed of 1.1 Gbps over 70 meters and 800 Mbps over 100 meters.
- On older unshielded cables, typical of most in-building cabling in Austria, the trial achieved speeds of 500 Mbps over 100 meters on a single line. However, when a second line was introduced, creating crosstalk between the two, the G.fast speed fell to only 60 Mbps.
- Vectoring was then enabled, removing the crosstalk and bringing the speed back up to 500 Mbps over 100m. This is a huge improvement over widely deployed DSL networks, which typically offer speeds of 5-30 Mbps, or VDSL2 vectoring networks supporting up to 100 Mbps. Fiber-to-the-home services typically range from 100 Mbps to 1 Gbps.
- G.fast, which is not yet standardized, won't be commercially available for several years. However, it is a natural evolution of VDSL2 that, with the help of vectoring technology, could allow service providers to more quickly and cost-effectively provide subscribers with broadband speeds from several hundreds of Mbps up to more than 1 Gbps over short distances.
Hans Pichler, Chief Technology officer at Telekom Austria Group, said: "Telekom Austria Group´s A1 was an early adopter of Alcatel-Lucent's VDSL2 vectoring because we understand the value of upgrading our existing copper infrastructure to give our customers the best possible broadband service. We are pleased to be working with Alcatel-Lucent at the cutting-edge of fixed broadband technology to look at the possibilities of G.fast vectoring."
Federico Guillen, Leader, Business Line Fixed Access, said: "As a leader in fixed broadband and a pioneer of vectoring - being the first vendor to ship 1 million VDSL2 vectoring lines - Alcatel-Lucent is ideally placed to help Telekom Austria understand the potential of G.fast and vectoring. G.fast underlines the specialist expertise Alcatel-Lucent brings to customers like Telekom Austria as they expand their footprint of ultra-broadband access coverage. While this is only a trial, the impressive results show the enormous potential of G.fast for service providers around the world."
