All about Fibre Optics
Fibre optic cables are thin strands of glass that carry data as pulses of light. They can send huge amounts of information over long distances very quickly.
Light travels along the fibre by bouncing off the inside walls, so the signal stays strong even over long distances. A single fibre can be thinner than a human hair.
They also bring fast internet into homes and schools.
