What is optical fibre?
An optical fibre is a thin, flexible filament of transparent material, usually glass, able to transmit light signals over long distances and at high speeds, averaging over 100 gigabits per second — like downloading an entire HD movie in one second.
The light travelling in the optical fibre is reflected by the fibre’s inner core, thereby maintaining its intensity and quality. In addition, the optical fibre is thinner than a human hair, with a diameter of about 0.1 millimetres.
It was invented in 1952 by Indian physicist Narinder Singh Kapany and today has multiple applications in medicine, art, military and space communication. In fact, one of its main advantages is that it allows the transfer of huge amounts of data in a very short time, ensuring a fast and stable Internet connection, which is essential in many different areas.
