Fibre Optic Cables - What Are The Maximum Distances They Can Run?

First developed in the 1970s, fibre optic communication systems have revolutionised the telecommunications industry. Fibre optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fibre – this is a strand of optically pure glass as thin as a human hair.

Because of its advantages over electrical transmission, optical fibres have largely replaced copper wire communications in core networks across the globe.

But there is sometimes some confusion over how far a fibre optic cable can be run, the table below should help to answer this question.
