Superfast Broadband comes in a number of guises and can create confusion. It is delivered by replacing the largest percentage of a circuit with fibre, reducing the losses over distance that happen with copper. This is known as Fibre to the Cabinet (FTTC). It can be misleadingly sold as fibre, with customers believing they have an end to end fibre connection. It is still a contended service and does suffer as more users subscribe to it.
