摘要： A glass fiber for use as a light waveguide characterized by a one piece member having at least one transverse opening extending through the fiber to subdivide a section of the fiber into two portions connected at each end by the zones of the fiber free of the opening. By cutting in the area of the opening, a branch fiber can be produced. Preferably, the fiber includes a pair of cores which are separated by the openings. The method includes drawing the fiber from a mass of softened glass and while in the softened state, forming the openings therein or by drawing the fiber from a preform having at least one transverse extending opening. Preferably the preform is formed by joining two members having flat surfaces together and the openings in the preform are formed by forming transverse grooves in one of the flat surfaces.

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.
