Abstract
It is necessary to know exact value of the full dispersion of waveguides, which leads to broadening and reduction of pulse amplitude for modeling laser radiation passage in quantum cryptography systems. The operation purpose was obtaining of dependences on a wavelength of various dispersion types according to the Sellmeier’ sequationand optical pulse radiation modelling in quantum communication systems. Dependences of the material, waveguide and chromatic dispersions on length of a wave according to the Sellmeier’s equation which allows to consider an optical fiber’s material are received. Distribution of a cryptographic impulse through fiber-optical communication lines of various extent is simulated
