CHEMICAL-VAPOR-DEPOSITION FOR OPTICAL-FIBER TECHNOLOGY

At the beginning of the seventies, a break-through took place in the t elecommunication research. The introduction of Chemical Vapour Deposit ion technology in the manufacture of optical fibres allowed both techn ical quality and economical convenience to realise optical networks, t hus beginning the telecommunication revolution. Since that moment, a g reat development of the CVD techniques has been performed, introducing several methods to produce fibres with geometry and optical propertie s optimised for different applications. An overview of the different m ethods is given, and the problems which have been to be solved in thes e years are described.
