摘要： For the production of glass fiber optical waveguides with increased tensile strength, these are drawn from a glass preform with a single-layer or multi-layer of additional sheathing of a glass material, with the material of at least the outermost layer in each case having a lower coefficient of thermal expansion as compared with the layer located underneath it or with the material of the preform. During the drawing process, the fiber is drawn from the preform in the cold state with increased tensile force of 70 to 200 cN.
