摘要： The present invention relates to a method for the manufacture of a high-tensile-strength light waveguide with a plastic layer on the optical fiber, in which a hardenable polymer precursor stage is applied to the optical fiber. Uniform, thick layers are produced in a single operation in a process comprising applying an oligomeric and/or polymeric polyaddition or polycondensation product to the optical fiber from a solution and subsequently irradiating with actinic light and/or performing a thermal treatment. The polyaddition or polycondensation product is made from a carbocyclic or heterocyclic compound which carries two functional groups suitable for addition or condensation reactions, and a diamine, a diisocyanate, a bis-acid chloride or a dicarboxylic acid. The carbocyclic or heterocyclic compound has in a position adjacent to the functional groups partially ester, amide, urethane or urea groupings which may be of an unsaturated nature. The light waveguides made by the method according to the invention are suitable particularly for purposes of optical information transmission.
