Abstract

Efficiency indicators optical telecommunication systems using modern optical technologies spectral wavelength multiplexing have been analyzed. Influence nonlinear effects in fibre-optic transmission lines in dispersion control mode on the basis of which methods for calculation efficiency indicators of optical information transmission systems and algorithms for determination parameters single-mode optical fibres in dispersion control mode have been investigated. Analytical expressions are obtained, allowing to estimate efficiency of optical signal transmission systems based on technologies of spectral WDM (Wavelength Division Multiplexing) and dense spectral multiplexing DWDM (Dense WDM) channels by wavelength.
