The global market for very-high-bitrate DSL (VDSL) grew by 49 per cent in 2014 and is set to quadruple in size by 2014, according to a report from IHS iSuppli.
In 2010 the VDSL subscriber base rose by 23.3 million, up from 15.6 million in 2009, and the analysts forecast is that this will grow to 60.1 million by 2014. In the UK BT has invested in the technology to get the fastest possible speed out of its current copper connections.
"As the broadband market switches from a focus on data to stressing wideband multi-service and multimedia, fatter pipes to receive content are becoming more desired," said Lee Ratliff, senior analyst for broadband and digital home at IHS.
"Peer-to-peer file sharing, online gaming, streaming audio, voice over IP and Internet protocol television (IPTV) now all could be operating within one home. Such heavy activity points likely to a future in which 50 to 100MB/s will be standard - which fits exactly with VDSL's capabilities."
VSDL, and since 2006 VSDL2, allows ISPs to boost the performance of existing copper connections up to 100MB/s. It is however degraded by distance from an exchange to a far greater degree than fibre and is seen as a bridging technology until fibre-to-the-home (FTTH) is deployed.
"The telco broadband market is undergoing a seismic shift," said Ratliff
"Newer technologies such as VDSL and FTTH have begun to emerge, while interest is waning within the industry for traditional broadband technologies like cable and ADSL."
