Explore the fascinating history of fibre optics, from its ancient origins with the Romans drawing glass fibres in 27BC to its modern-day applications in telecommunications, medicine, and entertainment. Discover how this ubiquitous technology evolved from a simple concept into a cornerstone of connectivity.

While fibre technology has become ubiquitous in today’s modern telecommunications networks, did you know that fibre optic technology has been around for a very long time and is quite simple in concept. Glass dates back to around 3000BC and the Romans were drawing glass into fibre as early as 27BC. So while fibre has become an everyday technology ranging from medical to telecommunications to entertainment applications, you can see from its history that fibre has come a very long way in a very short time.

The following is an historical chronology of some of the key milestones with regards to fibre optics.

~3000BC - Earliest known making of glass in the Bronze Ages.

~27BC - Romans draw glass into fibre.

1840s - Jacques Babinet guides light in water and bent glass rods.

1888 - Bent glass rods used to illuminate body cavities for medical purposes.

1920s - Microscope illumination achieved using bent glass rods.

1931 - Mass production of glass fibres conceived.

1951 - First discussions of using transparent cladding on glass or plastic fibres.

1959 - American Optical draws fibres so fine they can only transmit a single mode of light.

1960 - First lasers demonstrated.
