Free - space optical communication ( FSO ) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. Free space means air, outer space, vacuum, or something similar. This contrasts with using solids such as optical fiber cable . That technology is free - space optics (FSO).
This line-of-sight technology approach uses invisible beams of light to provide optical bandwidth connections.
The theory of FSO is essentially the same as that for fiber optic transmission.

The difference is that the energy beam is collimated and sent through clear air or space from the source to the destination, rather than guided through an optical fiber.
FSO ( free space optics ) is an optical communication technology in which data is transmitted by propagation of light in free space allowing optical connectivity. There is no requirement of the optical fiber cable. Working of FSO is similar to OFC (optical fiber cable) networks but the only difference is that the . There are several features and benefits from free - space optics that could make it the perfect communications system to suit your needs.
Authors: Abdulsalam Ghalib Alkholidi and Khaleel Saeed Altowij. Bell used beams of light to transmit voice conversations through the air, . The range of the potential application of FSO networks is extensive, from home to satellite. However, FSO networks have not been popularized . Millimeter wave communications.
A new technology without using fiber cable. Read this little awesome story on FSO. We have studied optical and electronic signal processing methods to overcome atmospheric turbulence, in links employing either coherent detection or direct detection. We have demonstrated free - space coherent transmission at mid- infrared wavelengths, where atmospheric effects are reduce using . At the Department of Communications and Wave Propagation several FSO-systems have been developed within . Free - space optics (FSO) - or telecoms systems based on free space lasers (FSLs ) - have attractions as an alternative to existing signal conduits such as fibre or wireless.
The technology also has the potential to become a . Given the relative newness of free - space optics (FSO) technology in commercial applications, few standardized metrics exist for comparing the performance of different systems. Free Space Optics (FSO) is an excellent supplement to conventional radio links and fibre optics. Our goal here is to explain some of the design issues surround- ing FSO systems and to provide sufficient information to allow potential users.
