What is free space optical communication system?

What is free space optical communication system?

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.

How does free space optical communication work?

Free Space Optics (FSO) transmits invisible, eye-safe light beams from one “telescope” to another using low power infrared lasers in the terahertz spectrum. The beams of light in Free Space Optics (FSO) systems are transmitted by laser light focused on highly sensitive photon detector receivers.

What is Fsoc technology?

Free Space Optics is a line-of-sight technology that uses invisible beams of light to provide optical bandwidth connections that can send and receive voice, video, and data information.

What is FSO channel?

Free Space Optical communication (FSO) is a wireless communication technology which uses light to transmit the data in free space. FSO has advantages like unlicensed spectrum and higher bandwidth. In this paper FSO system merits and demerits, challenges in FSO, and various channel models are discussed.

Why do we use free space in optical communication?

FSO is a communication system where free space acts as medium between transceivers and they should be in LOS for successful transmission of optical signal. This system can be used for communication purpose in hours and in lesser economy. There are many advantages of FSO like high bandwidth and no spectrum license.

What are the disadvantages of FSO?

Drawbacks or disadvantages of FSO ➨Power consumption is higher. ➨It is easy to intercept due to its propagation medium and hence it is less secure than OFC. ➨The FSO transmitted signal gets blocked due to trees, animals, buildings and other atmospheric conditions. Birds and scintillation cause beam interruptions.

What are the advantages of free space optical communication?

FSO lasercom offers substantial advantages over conventional radio frequency (RF) wireless communications technology such as much higher bandwidth (data rates), low probability of intercept for higher security, low power requirements, and much smaller packaging to make them portable.

What is the bandwidth of free space?

Free Space Optics (FSO) is a technology that uses laser beams via a line of sight optical bandwidth connection to transfer data, video or voice communications across areas ranging typically from 100m to a few kilometres at throughput bandwidths up to 1.5Gbps at frequencies above 300GHz of wavelengths, typically, 785 to …

What are the advantages of FSO?

There are many advantages of FSO like high bandwidth and no spectrum license. The transmission in FSO is dependent on the medium because the presence of foreign elements like rain, fog, and haze, physical obstruction, scattering, and atmospheric turbulence are some of these factors.

What means free space?

A theoretical region of space utterly devoid of physical matter, gravitational fields, and electromagnetic fields. A region devoid of physical obstructions that might hinder the propagation of electromagnetic signals.

What is free space optics and what role does it play in data networks?

FSO or Free Space Optics is a line-of-sight technology using light to provide optical bandwidth connections in which voice, video and data information can be sent and received simultaneously on invisible beams of light.

Where is FSO used?

FSO is a communication system where free space acts as medium between transceivers and they should be in LOS for successful transmission of optical signal. Medium can be air, outer space, or vacuum. This system can be used for communication purpose in hours and in lesser economy.

What is free space optic?

Free Space Optics is a line-of-sight technology that uses invisible beams of light to provide optical bandwidth connections that can send and receive up to 2.5 Gbps of data, voice, and video communications. It uses the same concept as fiber optics except without the cable.

What is optical communication technology?

Optical communication, also known as optical telecommunication, is communication at a distance using light to carry information. It can be performed visually or by using electronic devices.

What is wireless optical networks?

Advantages of Optical Wireless System It is immune to interference. It is highly secure as optical waves do not penetrate the walls. It provides higher data rate due to huge bandwidth available on fiber cable. As it operates using ISM unlicensed bands, license related issues are not required to be tackled with.

What is optical satellite communication?

Optical satellite communication is also known as Free-space optical communication (FSO) that uses an optical communication technology which uses light propagating in free space to wirelessly transmit data for telecommunication or computer networking.
