TYPES OF CABLE

Most of the data you send and receive over the internet travels by cable

COAXIAL CABLE

Often known as coax, these cables are thick and round, with layers of insulation surrounding a single central core. They can transmit ten megabits of data per second.

TWISTED PAIR

Also known as ethernet cables, twisted pairs were specifically made for connecting computers. Each cable contains four pairs of twisted wires, transmitting ten gigabits per second.

FIBRE

The fastest cables don’t carry data as electricity; they carry it as beams of light. At their centres they have a glass core capable of transmitting up to 100 gigabits per second.
