In 2009 Kao was awarded the Nobel Prize in Physics for his function. Plastic fibers, usually made of polymethylmethacrylate, polystyrene, or polycarbonate, are much less expensive to generate plus much more flexible than glass fibers, but their bigger attenuation of light restricts their use to much shorter one-way links in buildings or cars.

Through a procedure generally known as total inner reflection, light rays beamed in to the fiber can propagate in the core for excellent distances with remarkably tiny attenuation, or reduction in intensity. The diploma of attenuation over distance may differ according to the wavelength of the light and also to the composition here of the fiber.
By way of example, the appliance layer is accustomed to determine where, when and how much data should be despatched at a specific charge.
