Review of Free-Space Optical Communications Links
Increased needs for bandwidth require technology that goes beyond traditional copper lines. As internet traffic scales faster than Moore’s law, which is the exponential growth in technology, and digging to install lines in metropolitan areas becomes infeasible, the industry has realized the benefits of free-space optical communication. Free-space optical (FSO) communication links are attractive...
متن کاملFree Space Optical Communications System Pointer
Free Space Optical (FSO) communications pointing problems will be described and a solution presented. Conventional systems used in sea, land, and space are illustrated. Our integrated approach investigates three major problems areas: kinematics, structure, and dexterity. Their interrelationship will be discussed.
متن کاملFree Space Optical Communications: An Overview
Free-Space Optics (FSO), also known as fiber-free or fiberless optics, is an emerging technology that transports data via laser technology. It is a line-of-sight technology that currently enables optical transmission up to 2.5 Gbps of data, voice and video though the air, allowing optical connectivity without deploying fiber-optic cable or securing spectrum licenses. It is moving closer to bein...
متن کاملAn Introduction to Free-space Optical Communications
Over the last two decades free-space optical communication (FSO) has become more and more interesting as an adjunct or alternative to radio frequency communication. This article gives an overview of the challenges a system designer has to consider while implementing an FSO system. Typical gains and losses along the path from the transmitter through the medium to the receiver are introduced in t...
متن کاملRelay-Assisted Free-Space Optical Communications
The atmospheric lightwave propagation is considerably influenced by the random variations in the refractive index of air pockets due to turbulence. This undesired effect significantly degrades the performance of free-space optical (FSO) communication systems. Interestingly, the severity of such random degradations is highly related to the range of atmospheric propagation. In this thesis, we int...
