We are in a world that is rapidly depending on the technology. In the past years and for decades, fabulous expansion and development has been noticed in the field of different technologies such as communication and information. The increase of high speed has been used in video-conferencing, live streaming and also in the internet, the bandwidth of FSO is increasing hugely. Free Space Optics (FSO), known as optical wireless are systems of the telecommunication wireless that use free air from medium transmission to deliver optical data signals at high rates. Free Space Optics uses Light Amplification by Stimulated Emission of Radiation (LASER) and Light Emitting Diode (LED) for transmitting data, instead of closing off the data stream on all sides in a glass fiber; this data is broadcasting through the air at a range works in 780nm-1600 nm wavelength.
The use of these lasers is uncomplicated hypothesis which is similar to optical broadcasts using fiber-optic cables. The light goes through air more rapidly than the light in glass. That is the reason behind categorizing Free Space Optics as optical communications at the high speed as a light. These FSO are already being used in many fields to communicate between submarines.
Most fighter jets emit a lot of electromagnetic waves to reduce the amount of electromagnetic waves jets.
