Getting Ready for VDSL2 - How to get the Best Performance out of your Copper Lines

Hosted by

Andrew Long

Senior Product Line Manager, Access Business Unit

Andy Long joined EXFO in May 2008 in his current role. He brings to EXFO his telecommunications test industry experience in a variety of positions, including design, technical support as well as product and marketing management. Andrew graduated with a degree in Electrical and Electronic Engineering from the University of Plymouth in the UK.

The different types of DSL are designed to work on copper local loops, and deliver ever more bandwidth. Yet, often the challenge is not more speed, but reaching and connecting more customers. How do you get DSL further out to more customers, especially on long loops? It is quite a challenge to get broadband to go further on an aging plant designed for traditional telephone services. This webinar discusses the issues behind that and how to make DSL work more reliably on long loops.

To reach further out to more customers we have to consider three areas when deploying any type of residential DSL: 

  1. Which type of DSL is more suited (ADSL2, VDSL2, etc.)
  2. Loop length and quality
  3. Other signals and noise

We will  discuss:

  1. How far can DSL go? How fast?
  2. What types of DSL are best for longer loops? Why?
  3. How signals travel down copper pairs
  4. Faults that reduce signal strength (loss)
  5. Why there may be too much noise (interference)
  6. How to minimise interference

What you will learn:

  1. The best DSL profile/mode for longer reach
  2. Pair quality factors that affect signal strength
  3. Issues that create or allow too much noise/interference
  4. Techniques to reduce the effect of noise/interference
