Lasers have been considered for space communications since their realization in 1960. However, it was soon recognized that, although the laser had potential for the transfer of data at extremely high rates, specific advancements were needed in component performance and systems engineering, particularly for space-qualified hardware. Advances in system architecture, data formatting, and component technology over the past three decades have made laser communications in space not only a viable but also a attractive approach to intersate ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

Free Space Optics (FSO) communications, also called Optical Wireless (OW)
Bo Rong, Yi Qian, Member, IEEE, and Kejie Lu, Member, IEEE
Overview

Imagine a technology that offers unsurpassed reliability and

high-speed connectivity. A technology that can be installed globally is

easy to deploy, license-free and offers a fast, high ROI. That

technology is free-space optics (FSO).

Free Space Optics (FSO) communications, also called Optical

Wireless (OW) or Infrared Laser, refers to the transmission of

modulated visible or infrar ....etc
