Vectoring eliminates Far End CrossTalk (FEXT) and allows service providers to deploy

100 Mbps out to >1 km over two pairs of copper

VDSL2 with Vectoring Mass-Market 100 Mbps Service Delivery

VDSL2 w/ Vectoring: – Latest generation copper

access technology for FTTN architectures

– Mass deployable technology in 2013

– Delivers 100Mbps out to >1km/3kft with 2pr bonding

– Enables cost-effective and widespread delivery of 100M services

– Small form-factor DSLAMs optimized around vectoring coming to market

The solution to the problem of alien pairs is

to take a “system-level” approach to vectoring.

44

Vectoring Summary

Increases VDSL2 bandwidth – 50% or more; Attain 100Mbps per

pair

Works best on short loops – Less than 1.5km/5kft

A system-level approach is key – Any ‘alien’ service reduces

performance

45

Summary

Near-term requirement: 100Mbps

Make smart investments in the face of a rapidly changing landscape

Stay focused on customer experience, not technology for its own sake

Beware disruptive technologies and market entrants – Revenue erosion

– Undermine business case assumptions

Incremental investment with quick ROI mitigates risk

46

A Comprehensive Toolkit

Be technology-agile – Greenfield: FTTP is the obvious choice

– Brownfield: FTTP economics are challenging, FTTN is an effective alternative

Carriers must continue to leverage existing network to fund long-term fiber buildout

Successful carriers will combine both architectures to build a profitable network

The all-fiber future belongs to those who survive long enough to reach it
