“VDSL vectoring and other DSL acceleration technologies will prove vital in enabling operators in major markets worldwide to roll out superfast broadband quickly and cost-effectively. ” Stephen Wilson, Senior Analyst, Europe, Informa Telecoms & Media.

This report contains global VDSL subscriber forecasts by region and 24 major markets. It also contains detailed case studies on operator best-practice and incisive analysis and recommendations about the opportunities that the new DSL technologies present.


Next-generation copper technologies such as VDSL pair-bonding and vectoring are shaking up the competitive and political landscape for next-generation access broadband markets.

Operators and vendors are placing increasing importance on these technologies as a means to allow operators to offer superfast broadband speeds in a more rapid fashion than having to build FTTH networks. Regulators are also grappling with the complex consequences of this new wave of technologies, while the investment community is looking to understand what DSL acceleration means for potential returns.

An understanding of where these technologies will be applicable and the potential limitations that they face is therefore essential. In some cases, regulation may stymie DSL acceleration technologies and in other markets there may be structural issues, such as copper loop lengths and the availability of multiple copper pairs.

The usefulness of DSL acceleration technologies will therefore differ by market and so a granular quantitative breakdown by region and country is essential. As a result, the report includes detailed five-year VDSL subscriber forecasts for all regions and 24 countries worldwide.

The report also takes time to look at operators that have already deployed VDSL in order to draw key lessons about the technical and commercial strategies that have been successful for these operators and those that have not.

How will this research help you:

  • Quantify, with country and regional-level subscriber forecasts, the potential growth for VDSL.
  • Understand the next generation of copper technologies - including VDSL-from-the-central-office, pair-bonding, vectoring, phantom mode and G.Fast - that promise to increase broadband speeds over DSL networks.
  • Learn from case studies how successful operators have been with their VDSL rollouts.
  • Interpret the regulatory implications of next-generation copper technologies.

Analysis includes:

  • Technology analysis
  • VDSL-bonding strategies: A secret weapon to save time and money in the battle with cable
  • VDSL-vectoring strategies: The copper technology that's making FTTH look passe
  • To what extent are VDSL vectoring and sub loop unbundling incompatible?
  • VDSL-from-the-central-office: the cheapest and easiest NGA option for both incumbents and unbundlers
  • DSL acceleration: Phantom mode a longer-term option for operators
  • G.Fast: business rationale for copper 2.0 remains unclear

Case studies:

  • Belgacom's copper centric NGA strategy
  • O2 Czech Republic's VDSL-from-the - central-office strategy
  • Regulatory issues with vectoring and VDSL=from-the-central-office in Austria
