Performance Evaluation of FreeSpace Optical Communication Systems Using Visible Light Bands

Evaluating the Performance of Free-Space Optical Systems with Visible Light Bands FSO communication systems using visible light bands form a revolutionary concept of developing new generation high-speed, high-capacity data link solutions where conventional fibre-optic or radio frequency links may not suffice. This paper provides a comprehensive evaluation of the performance of FSO systems utilizing visible light bands by focusing on critical performance metrics: It also highlighted Q-factor, bit error rate, and the eye diagrams. A detailed elaboration of the Q-factor analysis is presented since this parameter controls the signal quality and system performance levels. The Q-factor is evaluated in terms of the BER to analyse the effects of multiple operational parameters, including atmospheric conditions, optical power levels, and modulation schemes, on the reliability and efficiency of the given communication link. Analysing these factors, we can characterise their impact on signal quality and stability of the system. Canonical examples incorporate eye diagrams as parts of a complete signal quality assessment system where we can look for problems such as signal deterioration, noise, and other types of perturbations that can influence performance. Our evaluation also includes simulations and practical experiments for comparing various FSO configurations and operation conditions. This paper thus demonstrates the opportunities and risks related to the use of visible light FSO systems and provides important knowledge regarding their applicability in urban and remote locations. Here we outline potential approaches to increasing the efficiency of the system’s functioning and suggestions on means for increasing the signal-to-noise ratio and decreasing the error rate. The submitted work benefits the progress of FSO technology, as it promotes the creation of stable and reliable communication channels in various operation conditions.
