fibre-optics communication lines. SUBSTANCE: single-mode optical fibre has a core and a shell. The radius of the core and the diameter of the shell are selected processing from definite conditions. The fibre refractive index is characterized by a stepped, trapezoidal or triangular profile. EFFECT: reduced dimensions of fibres for enhancing the carrying capacity of fibre-optics cables, reduced cost of manufacture. 4 cl, 5 dwg |
