Fibre broadband uses glass cables rather than the standard copper wires used in regular broadband connections.

Data is transmitted via beams of light, meaning it travels at light speed and won’t slow down over distance. 

My current provider already advertises it as Fibre, what is the difference?

Many providers will use the word Fibre within their package name, when it is not a true Full Fibre product. Full fibre is called FTTP (Fibre To The Premises) and the fibre cable runs directly in to your home. FTTC is Fibre To The Cabinet and only includes fibre to the green cabinet on your street or nearby. Your home is then supplied connectivity via a copper cable from the cabinet. 

FTTC speeds are typically up to 40Mbps or up to 70Mbps.
