In this paper, the ultimate limit of the signal to nonlinear noise ratio (SNRNLI) for high bit rate system operating near zero-dispersion wavelength is calculated. Carried out simulations revealed that the shape coefficient (Φ) is a very important factor that must be taken into account in the theoretical model.
Scilab toolbox for fiber optic communication systems simulation was developed, named SSS. The features of SSS simulator are presented by including examples of program code with short comments explaining the key instructions, followed by graphical presentation of simulation results. Scilab is an open-source alternative of Matlab and combined with SSS toolbox could be implemented in research and education.
In this paper we address the problem of the impairments in Radio-over-Fiber (RoF) transmission which occur in an optical link in a millimeter-wave (mm-wave) band, e.g. for 60 GHz carrier frequency. We carry out some basic relations between DSB, SSB and OSC modulation formats and than compare duobinary and RZ modulation by numerical simulations.
