BT has announced the commercial launch of its 'up to' 100Mbps fibre-to-the-premises broadband service. Exchanges in London and Exeter are the first to get FTTP upgrades. It was previously only available to residents of Milton Keynes via a BT trial. 

The fibre-optic broadband service will be available as BT Infinity Option 3. As of today a limited number of suburban London exchanges, plus ones in Chester, York, St Austell and Exeter will be able to deliver the FTTP service. As well as much faster downloads, the fibre-optic broadband service will offer upload speeds of up to 15Mbps.

Exchanges first to get FTTP broadband include Highams Park, Leytonstone, Ilford and Forest Hill in London, Ashford in Middlesex, Chester, York, St. Austell and Exeter. BT plans to roll out the service to more exchanges in the future.

The existing BT Infinity FTTC (fibre-to-the-cabinet) service offering downloads of up to 40Mbps is now accessible to more than 6 million homes and premises. Until now, the FTTP-based service was only available in Milton Keynes, where it was being trialled. 

“We are delighted to launch BT Infinity Option 3, which offers our fastest-ever speeds for consumers. We are seeing very encouraging take-up of our fibre-based broadband and we now have more than 300,000 customers,” said John Petter, managing director of BT’s consumer division.

“Today’s addition expands our product offering, so we now have three versions of BT Infinity offering high speeds that allow families to do more online at the same time. BT Infinity Option 3 matches the top speed currently available in the UK and beats the upload speed offered by Virgin Media’s best offering.”

BT recently revealed it will bring superfast fibre broadband to two thirds of the country by 2014, a year earlier than hoped. Under its £2.5bn roll-out BT had originally hoped to reach 66 percent of the UK with its fibre network that offers speeds of 'up-to' 100Mbps through a combination of fibre-to-the-premises (FTTP) and Fibre-to-the-cabinet (FTTC) technology by 2015. However the telecoms firm has bought forward some £300m worth of investment which now take place over the next few years and revised the deadline to 2014.

BT Infinity Option 3 costs £35 per month with unlimited evening and weekend calls.
