Abstract

In this research, the problem of the optical link in different fog cases was solved through the use of the proposed center balance with the RF link, where this center adjusts the power of the laser transmitter according to the damping of the optical link, where the length of the transmitted signal is increased which leads to overcome dispersion. Measurements are carried out by three fog laser sensors located at the beginning, middle and end of the optical link. These sensors generate voltage proportional to the amount of fog and then send these values ​​using radio waves RF to the equilibrium center, which calculates the average damping value and adjusts the power value of the laser transmitter according to the damping coefficient value. Simulated using OPTISYSTE programming environment and MATLAB environment, MIE dispersion was adopted in wireless optical link and transmitted signal wavelength 1550nm where quality coefficient was improved from 3.6% to 44.45% in moderate, light and very light fog
