Opis:: Nonlinear effects in optical fibres play an important role for transmission parameters in wavelength-division multiplexed telecommunication systems. Those effects cause an additional attenuation, distortion and inter-channel interference of the multi-wavelength optical signal. Therefore, it is important to optimise inter-channel wavelength span in a wavelength-division multiplexed system, and also the optical power and transmission bit-rate. Another drawback is a limitation of the number of the transmitted optical channels and network nodes. The paper reports the results of the analysis and computer simulations of the wavelength-division multiplexed transmission through fibre link in a presence of nonlinear effects: self-phase modulation, cross-phase modulation, Raman scattering, four-wave mixing. The analysis enables network designers to evaluate the system performance and to optimise transmission parameters.

Opis:: In the paper results of analysis of nonlinear phenomena in optical fibres: Self-Phase Modulation, Cross-Phase Modulation, Four-Wave Mixing and Stimulated Raman Scattering and their influence on Dense-Wavelength Division Multiplexed system performance are reported. Different nonuniform optical channel allocation schemes based on ITU Recommendation G.692 100 GHz frequency grid are compared with uniform channel distribution. The level of nonlinear cross-talk is determined for different levels of the total optical power. As an example a 10 Gbit/s D-WDM dispersion-shifted single mode fibre link with dispersion-compensating fibres is envisaged. The directions for optimization of the system design in view of actual international standardization trends are pointed out.

Opis:: In this paper we present results of an investigation into the power penalty introduced by Stimulated Raman Scattering (SRS) in WDM systems with concentration on application of dispersion-shifted single-mode optical fibres (G.653) and unequal channel allocation schemes. System parameters based on ITU-T Recommendation G.692 and analytic formulas were used in calculations. It is shown that SRS does present a practical limitation to the multichannel systems. We also indicate limitations of the G.692 Recommendation and we point at directions of study in the area of nonlinear phenomena and multichannel systems.
