DSL is still the most widely-used broadband access technology, according to the latest statistics.
In a study carried out for the Broadband Forum, industry analyst Point Topic found that of the 370 million broadband subscribers worldwide, 65 per cent rely on DSL technology.
The rise in the number of those enjoying connections via fibre-optic networks was also noted in the report presented at the Broadband World Forum Asia in Hong Kong.
According to Point Topic, ten million people are now connected through high-speed fibre-optic networks - the figure represents an increase of 33 per cent since the start of 2007.
George Dobrowski, chairman and president of the Broadband Forum, commented: "This report shows that although DSL remains the key vehicle for delivering broadband associated services, alternative access technologies, such as fibre, are increasing their footprints and their requirements need to be considered in our work."
It was also found that the growth rate of cable subscriptions has slowed to 18 per cent.
