How does it work?

The majority of UK broadband connections use telephone lines (ADSL). ADSL (Asymmetric Digital Subscriber Line) broadband is available across most of the UK, provided through a standard copper telephone line. 

Superfast broadband will be delivered by a cable, or fibre-optic, broadband network. These cables are made up of glass and plastic, which allows data to move much faster than along the copper pipes used by ADSL broadband. 

Superfast fibre broadband, as deployed by Openreach can currently be delivered in two ways:

Fibre-to-the-cabinet (FTTC) technology - where the fibre runs from the exchange to a local roadside cabinet. In addition to download speeds of up to 80Mbps, FTTC also delivers upload speeds of up to 20Mbps — and could deliver even faster speeds in the future.  

Fibre-to-the-premises (FTTP) technology - where the fibre runs all the way to the home or business. FTTP on demand offers the top current download speed of 330Mbps. According to the regulator Ofcom, the current average UK residential broadband download speed is 14.7Mbps.

The exact speed of your superfast broadband also depends on a number of additional factors: the length of your line from the green cabinet, the line quality and the equipment and internal wiring within your premises. The Black Country Local Broadband Plan is working to ensure that everyone gets as fast a speed as possible given their geographical location.
