VDSLPlus - Data Rates Up to 150Mbps and Extended Reach Exceeding 4 KM

12.06.2003


Addressing the market demand for ever greater reach for VDSL and ever greater bandwidth over a single pair, Infineon Technologies (FSE/NYSE: IFX) and Metalink (Nasdaq: MTLK), today announced they are each developing VDSLPlus, which introduces a fifth-band extension of standard VDSL technology. VDSLPlus will enable service providers to offer scalable DSL services ranging from short range applications at data rates up to 150 Megabits per second (Mbps), to long reach applications that allow for more than 4Mbps rates over distances of 4km (13,200 ft) using the same line-card and Customer Premise Equipment (CPE) designs.

VDSLPlus will use a new frequency “band” above the current 12 MHz limit, as defined by international VDSL standards, to achieve the highest speeds ever reached in data transmission over standard twisted-pair copper wire. The benefits of the extended QAM VDSL technology include:

  • Delivery of over 150 Mbps aggregated bandwidth over single-pair copper

    wire - at more than 300m (1000 feet).
  • Reach of over 4km (13,200 feet) at speeds exceeding 4 Mbps.
  • Compliance with all relevant VDSL standards’ requirements including:
    Band Plan 998, 997, and those defined by the Chinese CTSI as well as any
    proprietary band plans.
  • Spectral compatibility and co-existence with narrowband and legacy DSL
    services including POTS, EuroISDN, TCM-ISDN and ADSL.
  • Support for both Ethernet and ATM over VDSL

"Infineon and Metalink continuously work to extend the capabilities of QAM VDSL, each making great strides in advancing the technology. As Service Providers and Carriers have mass deployed and gotten familiar with QAM VDSL over the four years it has been in the market, their demands have grown for increased VDSL bandwidth and reach, while they want QAM to maintain its highly cost effective, scalable deployment model. Metalink and Infineon are committed to collaborating with other industry leaders in extending the open QAM VDSL specifications and definitions to continuously meet this demand while preserving strict compliance to international standards," said Tzvika Shukhman, Chairman and CEO of Metalink.

Metalink and Infineon continue to be committed to teaming with other QAM PHY and system companies to promote VDSLPlus standardization in the various standar-dization bodies and to extend the companies’ already proven interoperability to the new technology. The two companies are the only suppliers to have demonstrated fully interoperable, commercially available VDSL products.
" The accelerated market demand for enhanced VDSL drives the cooperation between Metalink and Infineon, especially in Asia Pacific and Japan where QAM VDSL is a huge ongoing success. VDSLPlus is an extension to field-proven QAM-VDSL technology, incorporating enhanced integration levels, higher bandwidth capacity, and greater reach capabilities. With more than two million QAM VDSL lines in service generating revenue for Operators and more than a hundred system vendors who already offer QAM-based VDSL platforms, QAM is accepted as the de-facto line code for VDSL,” said Christian Wolff, Vice President of Infineon’s Communications Business Group and General Manager of the Access Business Unit.

QAM VDSL chipsets and systems, supporting the ITU, ETSI, Chinese, and ANSI band allocation plans, provide very high speed data transmission rates over robust, noise-immune QAM links enabling simultaneous video, data, and voice services over single-pair copper wires. The inherent simplicity of the QAM line code is demon-strated in superior cost and power advantages over competing VDSL line codes, yet with QAM’s sophisticated features and benefits. These advantages are further emphasized with the distance and speed increase available only in QAM VDSL with VDSLPlus technology.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
