What is FSO known as?

Free-space optics (FSO), also called free-space photonics (FSP), refers to the transmission of modulated visible or infrared ( IR ) beams through the atmosphere to obtain Broadband communications.

What does FSO mean in networking?

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 are the advantages of FSO?

An FSO system offers many features: low-cost set-up and operation, bandwidth on par with fiber optic cables, light-speed transmission, resistance to signal interception, and license- and regulation-free use.

What do you mean by optical communication?

Optical communication systems transmit information optically through fibers. This is done by converting the initial electronic signals into light pulses employing laser or light-emitting diode light sources.

How does FSO overcome scintillation?

Various types of optical amplifiers such as EDFA, SOA, gain-controlled amplifier and black box model of amplifier can be used to improve the performance of FSO thereby hampering the effect of scintillation.

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 are the types of optical communication?
