Abstract

—Free space optical (FSO) communication technology that wirelessly transmits data through light propagation in free space has drawn increasing attention from researchers. Optical intensity irradiance and atmospheric turbulence severely degrade the system’s performance, causing the signal to be transmitted poorly. The probability of an outage is considered one of the key performance indicators for the assessment of all possible fading states. However, this study observed a probability of outage that is linked to the consumption of transmit optical power under a number of link distances, data rates and weather parameters like haze, moderate and heavy rain. The analysis has been carried out through a MATLAB simulation. It is evident that, among 0.2, 0.5 and 1.0 bits/ channel, the lowest power consumption can be achieved at 0.2 bits/ channel with a 2.0 km propagation distance, which is 14 dBm for the probability of outage 10-9 under moderate rain. Furthermore, in all-weather parameters mentioned in this paper, 0.2 bits/channel at 2.0 km can establish an optimum outage with the lowest power transmission.
