Free Space Optical Communications: An Overview
نویسندگان
چکیده
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 being a realistic alternative to laying fiber in access networks. This paper presents an introduction to FSO and the current state of its technology and market.

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 کاملA Survey of Terrestrial and Free Space Based Optical Communications Systems
A low-level operational overview of terrestrial and free space optical communications systems is presented. Communication topics such as modulation, multiplexing, and detection are discussed in relation to optical links. Negative channel effects such as dispersion and absorption are investigated with respect to their impact on the channel and the associated bit error rates. The challenges posed...
