Abstract
An optical fibre with a core of glass and a cladding of plastics. In accordance with the invention, the glass is a sodium borosilicate glass containing refractive index-raising oxides, while the plastics is an optically low-attenuation plastics with a low refrective index, whereby a high numerical aperture is obtained in the optical fibre.
