‘Up to 38Mbps’ is a term that describes the slower type of fibre broadband, also known as FTTC (Fibre to the Cabinet).
FTTC uses copper telephone lines to connect you to a green street cabinet near your home before handing the connection over to fibre optic cables.
Although the maximum speed is ‘up to 38Mbps’ you are unlikely to get download speeds as fast as this in everyday use. The quality of an individual connection can vary between customers depending on the distance between your home and the nearest street cabinet, as well as how crowded your cabinet is with other users.
‘Up to 38Mbps’ broadband is a significant improvement over ‘up to 17Mbps’ broadband because of the massively increased stability of fibre optic lines. This means you’ll have much more reliable broadband, especially during peak times.
