Performance of Free Space Optical Terrestrial Link under Dense Fog Conditions

Investigating Wavelength Dependency of Terrestrial Free Space Optical Communication Link

Free space optical communication involves fiber-less optical based data transmission using visible and infrared bands of the spectrum. This technology has gained huge popularity in the past decades. In recent past a lot of research has been carried out to improve the FSO link performance which is seriously affected due to atmospheric inconsistencies. This paper investigates the performance of f...

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...

Free Space Optical Link Performance Evaluation using AODV and DYMO

Free space optical network gained increasing visibly as a broadband communication network over traditional wireless networks because of their high bandwidth (up to Gbps), low cost easy installation and also license free long range spectrum. Existence of line of site and alignment between the nodes is one of the key requirements for free space optical communication. In this paper the free space ...

Terrestrial Coherent Free-Space Optical Communication Systems

In the past three decades, the demand for high-speed communications has increased dramatically, while fiber optical communications has been applied in the majority of data transmission networks. Optical fiber has advantages over existing copper wire in long distance and high demand applications. The ever increasing need for higher bandwidth and higher speed optical data and communications trans...
