Copper or Fibre cables
Broadband typically comes into your home via a telephone line. There are two main types of cable for doing this – copper (ADSL) and fibre (fibre optic).
Broadband speed is impacted by the type of cable into your home and the distance from your house to the nearest exchange (either the local telephone exchange or the cabinets you see in the street). Fibre cables are faster than copper ones.
So, a fibre connection in a house that is close to the cabinet will have a faster broadband speed than a copper connection in a house that is further away from an exchange.
