How TUBE TUNNELS will be used to deliver ultra-fast full fibre broadband quick enough to download a two-hour HD movie in 25 seconds to London homes (let’s hope it’s quicker than the District line!)

  • Gigabit broadband speeds will be delivered using fibre optics in Tube tunnels 
  • The plan targets ‘not spot’ areas where connectivity is particularly poor  
  • Mayor of London says high-speed connectivity is ‘crucial’ for businesses
  • Full fibre is currently only available to around 11% of properties in the Capital

Properties in London are set to benefit from a £10 million investment in full fibre broadband using Tube tunnels and public buildings to deliver gigabit speeds.

Mayor of London Sadiq Khan announced the latest upgrade from copper cables to full fibre optics, in a bid to help the capital catch up with other cities across Europe.

Full fibre, which is fast enough to download a two-hour high definition movie in about 25 seconds, is only available to around 11% of properties in London at present.

The plan will start with 118,000 premises in south London and hopes to tackle so-called ‘not spot’ areas where connectivity is particularly poor.

Tube tunnels will carry fibre optic cables capable of delivering gigabit broadband speeds to homes and businesses across London

‘London’s future digital connectivity will be built on fibre,’ Mr Khan said.

‘High-speed connectivity is crucial for businesses of all sizes and sectors, not to mention Londoners accessing digital services at home and around the city.

‘This represents the largest investment in connectivity City Hall has ever made – the funding I’m announcing today unlocks the potential for us to use the Tube network and public buildings in bringing gigabit-speed connectivity to Londoners currently putting up with poor service.

‘I hope this provides the catalyst for further investment from the public and private sectors – I’m urging them to match my ambitions to get all Londoners connected.’

Mayor of London Sadiq Khan said that high-speed connectivity is ‘crucial’ for businesses of all sizes and sectors

The investment will cover the installation costs of linking fibre optic cables to public buildings, such as community centres and libraries, as well as reducing the cost to providers of laying cabling between the public buildings and Londoners’ homes and businesses.

WHAT IS FIBRE OPTIC BROADBAND?

Fibre optic cables involve tiny tubes that are about as thick as a human hair and are reflective on the inside.

They transfer information by sending flashes of light through the tubes.

This bounces off the reflective walls and along the cable. 

These flashes of data are then received and interpreted at the other end.  

City Hall says the additional funding brings its total investment in full fibre connectivity to more than £30 million, which will help more than 400,000 homes across London.

‘We’re delighted that we can help increase connectivity across the city by using the London Underground to help provide better broadband internet,’ said Shashi Verma, chief technology officer at Transport for London.

‘This work is on top of our wider plans to remove one of London’s biggest not-spots by bringing 4G to the Tube network, with the first section on track to go live from March 2020.’
