Cell phones, video game consoles and even computers would have never become normal everyday objects, had the first fibre optic network not been installed in 1979.
At the time, it connected Montreal and Quebec City and replaced all earlier technologies (copper cables, radio waves, etc.), which made it possible to transmit 32,000 conversations at the same time.
In Saint Laurent, Nortel manufactured the fibre itself, which was made out of glass or plastic, and all equipment that made it possible to convert electronic signals into optical signals and vice versa.
Bell was then in charge of installing the urban and long-distance fibre optic network, which now covers almost all of Québec. This company also created a research centre in Varennes that was able to connect fibres to each other and discovered different installation methods.
But the use of optical fibre was not limited to television, telephone and computer data.
Combined with the laser, it allowed doctors to eliminate kidney stones, explore inside the body and operate on the eyes.
It equips the navigation systems of rockets and satellites, and, a little closer to us, traffic lights and lighted signs.
Thanks to optical fibre, we can light up tinsel on Christmas trees.
