Abstract
A method and apparatus for manufacturing a graded-index plastics optical fiber of continuously varying index profile, starting from a particular polymer P and a particular compound M1, the method including the steps of: preparing two compositions of different refractive index, allowing the compositions to diffuse one into the other, and spinning the compositions so as to obtain the fiber, wherein, prior to extrusion, the two compositions are subjected to active mixing, and extrusion of the fiber is followed by curing.
