Chemical Vapour Deposition for Optical Fibre Technology

At the beginning of the seventies, a break-through took place in the telecommunication research. The introduction of Chemical Vapour Deposition technology in the manufacture of optical fibres allowed both technical quality and economical convenience to realise optical networks, thus beginning the telecommunication revolution. Since that moment, a great development of the CVD techniques has been performed, introducing several methods to produce fibres with geometry and optical properties optimised for different applications. An overview of the different methods is given, and the problems which have been to be solved in these years are described.
