ABSTRACT:
The invention relates to a method for manufacturing a hihg-tensile strength optical waveguide with a plastic layer of the epoxy-acrylate type located on the lightguide fiber, wherein a radiation-hardenable prepolymer is applied to the lightguide fiber immediately after the fiber-drawing process. The invention provides for the use in such a method of a preopolymer, which can be hardened by actinic radiation, of at least one acylated hydroxy ester of acrylic and/or methacrylic acid and an epoxide with n.ltoreq.3 epoxide groups per molecule. The optical waveguides manufactured by the method according the present invention are suitable particularly for purposes of optical information transmission.
