During the 1980s, France Télécom wished to develop a modern broadband infrastructure to meet future needs and to continue the modernisation of its network. The network evolved and became modernised, and optical fibre replaced coaxial cables. An optical fibre is a very thin wire made of glass or plastic surrounded by a plastic sheath.

In 1983, in Biarritz, optical fibre was tested as a transmission medium.
In large companies, the videophone made it possible to conduct meetings at a distance while being able to see the participants.

The arrival of fibre optics allowed several types of high-speed information to be transmitted over the same network: data, voice, and images.
