MODEL RELEASED. Optical fibre manufacture. Techni- cian by a control panel in a glass factory which makes optical fibres. The control panel is used to monitor and control complex production processes. Optical fibres are made from flexible glass that has a high refractive index. Each fibre is then coated with an outer protective layer that has a low refractive index. Light beams travelling through the glass are internally reflected instead of passing out into the coating. The light may travel along the entire cable with little absorption. Bundles of optical fibres may be used to carry images,or high volumes of data such as telephone conversations.
