By the time the London Olympics are held, you could be lapping up broadband speeds of up to 50Mbps. That's because BT is currently thinking through plans to adopt a cable fibre network that would significantly boost broadband speeds, BT top brass Sir Christopher Bland told the Financial Times late last week.
The technology in question is VDSL2 (Very High Speed Digital Subscriber Line 2) alongside a BT concept called FTTC , or Fibre To The Cabinet or Kerb. 'Cabinet' in this case means those little green boxes BT handily dots round on street corners. Some 85,000 of them exist, according to ThinkBroadband .
However, a major barrier to fibre adoption is the cost - estimated to be around the £4 billion mark. The problem is that for BT's shareholders there would be little comeback on the outlay for some time after installation. Unless, that is, VOD (video-on-demand) or services such as BT Vision start to convince consumers that they should be spending more to secure a high-bandwidth line into their homes.
From the cabinet to the home is where VDSL2 comes into its own as, like ADSL, it can use the existing copper-wire network up to a distance of 1km.
