Resilience of long range free space optical link under a tropical weather effects

Availability Prediction Methods for Terrestrial Free-Space- Optical Link Under Tropical Climate

Received Jan 11, 2018 Revised Mar 8, 2018 Accepted Mar 22, 2018 Free-space optical (FSO) links provide high speed point-to-point wireless communication, but its availability can easily be affected by weather conditions. In heavy rainfall regions, FSO links are relatively sensitive to rain. Availability prediction of FSO is indispensable part, especially in tropical areas. In this paper, methods...

Link Range of Free Space Laser Communication System

In this paper a model analytical description of a Free Space Laser Communication System the type ground-tospace is constructed. It is used for quantitative determination of the maximum range between transmitter and receiver depending on the bit error rate (BER). The laser radiation extinction in the atmosphere is accounted for by means of the visibility.

Modeling of RF Waves in Free Space Optical Communication System Under Gamma-Gamma Turbulent Channel Effect

In this paper, an enhancement design of communication system using optical radio frequency (RF) waves in free space optical communication (FSO) system is presented. To our knowledge, it is the first time that the effect of Gamma-Gamma turbulent channel model on the performance of the proposed system is analyzed and simulated. To obtain an optical communication system with good performance and h...

Development of Free Space Optical Link for Broadband Data Communication

To transfer high speed data streams, a line of sight (LOS) broadband free space optical (FSO) communication link has been designed between two private local LANs located at an aerial distance of about 2 km. A laser diode (LD) – avalanche photodiode (APD) combination operating at 1550nm is used to work as an optical trans-receiver system while an Erbium-doped optical amplifier (EDFA) is used to ...
