Home Fibre Plans Survive Downturn
The latest figures on superfast broadband delivered by fibre to the home (FTFH) shows 18% growth over the last survey compiled in late 2008.
The continued growth suggests that the global economic downturn has not hit plans to build a fibre infrastructure.
Sweden tops the list of nations roiling out the technology, with 10.9% of its broadband customers using fibre.
Karel Helsen, president of Europe’s Fibre -To- The- Home Council, said the growth matched predictions that were revised when the credit crunch started to make itself felt.
By 2012. the FTTH Council expects that 13 million people across 35 European nations will have their broadband delivered by fibre. Such services would start at speeds of 100 megabits per second (mbps) , said Mr. Helsen.
Around Europe more than 233 projects were underway to lay the fibre that would connect homes or buildings to the net, said Mr. Helsen. Many of those, he said, were being operated by local governments or smaller net firms.
They were interested in FTTH because of the economic and social benefits it brought, said Mr. Helsen.
The low delay in data transfer in high - speed fibre networks made possible novel uses of broadband ,he said.
"No delay is very important," he said," specifically if you talk about applications that are time dependent such as personal communications, conference calls or video calls where delays cause a lot of interference. "
While early FTTH services were concentrated in cities, said Mr Helsen, many more were reaching out to rural areas for e - health and e - learning projects.
Separate studies show that an FTTH infrastructure can have a direct impact on local economic output, said Mr Helsen.
The UK, France and Germany have yet to break into the list of top ten FTTH nations.

A.To introduce the development of fiber projects in Europe.
B.To praise Sweden for its high percentage of customers using fiber.
