There are three main types of broadband connection that link the local telephone exchange to your home or office: ADSL (asymmetric digital subscriber line) uses copper cables to a street-level cabinet or junction box and on to the house FTTC (fibre to the cabinet) uses a faster fibre optic cable to the cabinet, but then copper cable from there to the house FTTP (fibre to the premises) uses a fibre optic cable to connect to households without using any copper cable
