Another 20 million fibre-optic broadband lines were added worldwide during the first half of 2013, it has been revealed.
Research conducted by Point Topic revealed that super-fast, fibre-based services accounted for 25 per cent of all connections at the end of June 2013.
This was up from 22 per cent at the end of the first quarter of the year.
Point Topic said 7.7 million copper broadband subscriptions were lost in Q1 and Q2 as more households and businesses signed up for fibre services.
Overall, the number of fixed broadband customers increased to 656.5 million during the second quarter of the year.
Subscriber numbers increased by 0.7 per cent between April and June, but this was down from the two per cent growth rate witnessed between January and March.
Indeed, Q2 2013 saw the slowest quarterly growth in internet connections since 1998, with the loss of half a million subscribers in China contributing to this trend.
