The number of businesses and consumers signing up for fixed-line broadband services is continuing to increase.
A study conducted by ABI Research indicates that there were 539 million users with a fixed connection at the end of Q2 2011.
This represented an eight per cent increase on the previous three-month period.
Jason Blackwell, Practice Director at ABI Research, explained that broadband rollouts in the developing world are set to drive adoption rates in particular.
"Customer net addition is stronger in emerging markets," he stated.
Based upon current adoption levels, ABI Research expects the number of fibre-optic broadband lines to more than double over the next five years.
The firm expects the total number of fibre customers to rise from 69.6 million in 2011 to 142 million by 2016.
However, fibre broadband is also set to become more popular in the UK as BT continues to roll out the technology across the country.
The broadband provider is currently investing £2.5 billion upgrading telephone exchanges across the UK to support fibre broadband services.
UK households and businesses are able to take advantage of fibre broadband services by signing up for a BT Infinity deal.
Virgin Media is also deploying fibre broadband services in the UK, albeit on a smaller scale.
Around four million UK homes are now able to take advantage of the firm's 100Mb broadband network.
Recent research conducted by Point Topic found that global fibre broadband subscriptions rose at a rate of 2.9 per cent during the first quarter of 2011.
