Free Space Optics: Easy and Cost-Effective Medium for Communication

Free space optics (FSO), also called Free-space photonics (FSP), is a technology line that uses lasers to provide optical bandwidth connections that transmit data for communication and computer networking. FSO is capable of voice and video communication through the air, allowing optical connectivity of several Gbps of data without requiring fiber-optic cable.

FSO also refers to transmitting infrared beams (IR) through the atmosphere to obtain broadband communications. FSO technology can function for several kilometers as long as there is a clear sight for signal transmission. FSO technology is also considered an alternative to a line-of-sight (LOS) communication system.

FSO communication can provide high data rates using links as a medium that helps transfer data from a few hundred meters to a few kilometers. These links act as a mediator, and they are as follows:

  1. Inter-building communication

  2. Indoor infrared (IR) or VLC,

  3. Free-space laser communications, including airborne, deep space missions, and space-borne.

  4. Chip-to-chip communication

Free space optics technology is used daily in several applications, such as telescopes, lenses, lasers, and fiber optics.

What are the applications of Free Space Optics?

Frees Space Optics (FSO) is used for several purposes, such as

  • Point-to-point LOS links

  • Computer networking and telecommunication

  • Security applications

  • Communication between spacecraft, including satellite constellation

  • Temporary Network Installation for specific event purposes

  • For Military applications such as the transfer of sensitive data to the air force

What are the Pros and Cons of Free Space Optics?

FSO is used for serval purposes, but there are some pros and cons of using FSO technology


  1. Low error rates compared to other

  2. High Bandwidth to cost ratio-

  3. No need for License and regulations

  4. Full Duplex Communication

  5. Low initial investment

  6. Low power usage per transmitted bit


  1. Atmospheric absorption

  2. Increase in pollution levels

  3. Beam dispersion

  4. Pointing error

  5. Temperature variations

What is the future of FSO technology?

The FSO technology requires less cost and time to set up. The demand for Free Space Optics is growing rapidly as global telecommunication companies launch advanced networks for better communication, such as 5G and 6G. The demand for FSO technology will grow significantly in the coming years as it is cheaper than other optic fibers and has easy installation. The increasing use of Artificial Intelligence in telecommunication can create new opportunities for FSO technology in the future for various applications.
