Mr Elizade said that DSL, which uses existing copper access networks to deliver broadband therefore lengthens the useful life of existing copper structures, may not be able to cope with demand in the longer term.
Estimating that fibre-to-thehome deployments would reach over 14 million in 2012, compared to 2.5 million in 2006, Mr Elizade noted how the arrival of high-definition video and other entertainments through broadband would necessitate the use of different technologies.
He said: "Several technologies are available to meet the delivery of bandwidth demand, of which fibre in the local loop and in particular fibre-to-the-home, is future-proof."
Fibre would need to be deployed deeper into the network, possibly into homes and buildings, in order to meet future bandwidth requirements, he added.
