Attempting to stretch copper for a 100Mbps broadband target shows up the huge
variations between legacy network topologies: it could work well in the final
third in some countries, but may have limited impact in others.
Vectoring, pair-bonding and phantom-mode technologies promise greatly improved
rate-reach metrics for copper, as well as faster, cheaper roll-outs. This
Viewpoint examines the potential of these technologies for meeting the
European Commission's Digital Agenda targets for coverage of 30Mbps and
100Mbps broadband - also known as ‘superfast' and ‘ultra-fast'
This Viewpoint provides:
- analysis of the rate-reach of accelerated DSL technologies
- models of local and cabinet loop topologies in real networks
- an assessment of the potential for 30Mbps and 100Mbps coverage on copper
- an assessment of the role of copper in delivering 50% take-up in 100Mbps
service by 2020.

1 The ITU standard G993.2 for VDSL2 specifies eight implementation
(configuration) profiles that are subsets of the full suite of VDSL2
capabilities. Each profile targets different deployment scenarios, and
provides different levels of upstream and downstream bandwidth. This leads to
simplified, optimised system designs. A summary of the profiles is provided in
the Annex to this Viewpoint. A more-detailed discussion of accelerated DSL
technologies will be presented in a forthcoming Viewpoint.
