Fibre to the home (FTTH) / Fibre to the premises (FTTP) is the delivery of a communications signal over optical fibre from the operators switching equipment all the way to a home or business, thereby replacing existing copper infrastructure such as telephone wires and coaxial cable.
Fibre To The Cabinet (FTTC) typically refers to a broadband connection which uses high-speed optical fibre cabling between the local exchange and a cabinet in the street close to the consumers premises. The connection between the cabinet and the customer then uses the existing copper wiring from the telephone network. This results in much higher potential broadband speeds.
