Fibre broadband is also known as FTTC broadband, or Fibre to the Cabinet. Fibre broadband deals are usually listed as speeds ‘up to 38Mbps’ and ‘up to 76Mbps’.
Fibre broadband is sometimes called ‘superfast broadband’.
All of these terms are talking about the same thing. It’s a connection that uses a copper telephone line to connect your home to a green street cabinet, then a fibre optic cable to connect that cabinet to your ISP and give you access to the internet.
Because the connection also involves copper telephone lines, the name ‘fibre broadband’ can be pretty misleading.
Connections that use only fibre optic cables with no copper are named ‘full-fibre broadband’.
It is important to be aware of the different names because the difference in speed is staggering. A full-fibre connection is typically more than 10 times the speed of ‘fibre broadband’. As of 2017, full-fibre broadband is only available to around 2% of UK homes and business.
