One of the noticeable non-linear properties in Li-Fi technology is the four-wave mixing occurrence. Mixing consequence is booming when the segment matching disorder is fulfilled. It only happens for particular groupings of fiber diffusion and signal occurrences. It is a very disagreeable transmission phenomenon happening in a translucent optical network based on Li-Fi, but it can be recycled favorably for implementing optical strategies such as wavelength converters, parametric amps, optical multiplexers or de-multiplexers, chromatic scattering compensators, as well as a gesture to noise regenerators. This paper discusses the consequence of channel spacing, dispersion, optical fiber length and the dissimilarity of input power in the Li-Fi technology to reimburse the consequence of mixing of frequencies when realized in a short haul situation. The approach used is match filtering with pulse shaping to increase the quality factor with less bit error rates and the whole simulation is taken place in MATLAB.
