Five interesting facts about fibre optic cables

1. Fibre optics has a longer history than you might think
Although fibre optic cables first appeared in the 1950s, fibre optic technology originated long before the 20th century. As far back as Roman times, glass was being pulled into fibres. The first optical telex was invented by the French Chappet brothers in the 1790s. In the 1840s, two physicists demonstrated that light could be refracted by water jets in fountains. Date In 1854, a British physicist used a stream of water to prove that light could be bent. This was followed in 1880 by Alexander Graham Bell’s invention of the fibre optic photophone telephone.

2. Fibre optic cables are not as fragile as they may seem
Fibre optic cables are made of glass or plastic, making them much more durable than traditional copper cables. They are resistant to corrosion, water damage and temperature fluctuations, making them ideal for use in harsh environments. Some aspects of glass fibre require more care, but fibre optic cables are designed to work in the toughest environments. For a quick comparison, fibre optic cable can withstand more than 200 pounds of tension (depending on the design); while category-rated Ethernet cables are limited to about 25 pounds (according to TIA/EIA-568A standards).

3. Fibre optic cables also support wireless networks
Telecommunications companies rely heavily on optics to carry wireless signals and data from towers back to the central network. Fibre optics is their best choice because of its high bandwidth, low attenuation, and ability to operate over very long distances.

4. Sustainability
Fibre optic cables have less environmental impact than traditional copper cables because they are made of glass or plastic and are more energy efficient.
We can all do our part, and fibre optic cables are no exception. The amount of energy it takes to send a flash of light through a fibre optic cable is much less than it takes to send electrical signals. Less energy means less carbon, fewer emissions, and greener operations.

5. Fibre optic cables are not a one-trick pony
They are not limited to transmitting voice, video and data only. They are now being used in many applications, including:
·         Hydrophones (seismic and sonar)
·         Imaging Optics
·         Digital signage
·         Spectroscopy – the study of the interaction of matter and electromagnetic radiation
