optical fibre

Fibre optic cable, also known as optical fibre, is a very fine glass strand that allows rapid transmission of data, using modulated light beams. It is usual to put many strands together in a single cable, each one capable of carrying one or more data signals. Fibre optic cable provides interference-free, secure data transmission and, unlike metal wires, is not subject to corrosion.
