Free space optics communication is widely used in satellite communication
Free space optics communication is a type of telecommunications and computer networking technology that utilizes light propagating in "free space." In this context, "free space" means air, outer space, a vacuum, or something similar. Solid optical fiber cable is one example of free-space optical communication. This kind of cable can be used to transmit data at extremely high speeds. To transmit data, the light must travel through an unobstructed path.
The basic principle behind
Free-Space Optics (FSO) is that the data must be transmitted above the earth's
atmosphere. The atmospheric conditions create the biggest challenge for FSO,
but many drawbacks can be overcome by correct wireless network planning and
redundancy systems. Nonetheless, it is still important to keep these in mind.

An optical fiber connects the two
heads, and the resulting light beam carries information. The transmission
window of an FSO laser is characterized by the wavelength and the atmosphere's
absorption coefficient.
The range of free space optics
communication wireless network is typically between one hundred and two
kilometers. The distance between two units directly impacts the signal
strength. The shorter the distance between the two units, the higher the
performance. Typical applications of FSO include satellite communication and
telecommunications backhaul. Despite its inherent drawbacks, the benefits of
this technology are undeniable. The main benefit of this technology is its low
latency and high-bit-rate. Moreover, FSO provides enhanced security and
reliability.
One of the major drawbacks of FSO
is that it cannot be used in turbid environments. A single beam in a FSO system
will not transmit a signal at all, which can be disrupted by physical
obstructions. Another major drawback of this technology is its sensitivity to
atmospheric conditions. But fortunately, these issues can be easily mitigated
with the proper planning and redundancy systems.
