Free space optical (FSO) communication is a wireless communication technology that uses light as the transmission medium to transmit data over the air. FSO communication systems operate in the infrared spectrum and use lasers or LED sources to transmit data over a line-of-sight path.
One of the main advantages of FSO communication is its high bandwidth potential. FSO systems can transmit data at very high speeds, making them suitable for high-bandwidth applications such as video streaming and data transfer. Additionally, FSO systems are immune to electromagnetic interference, making them a reliable choice for communication in environments where electromagnetic interference is a concern.
Another advantage of FSO communication is its low cost. FSO systems do not require costly infrastructure such as towers or cables, making them a more cost-effective option for communication in certain situations.
However, there are also some limitations to FSO communication. One of the main limitations is that FSO systems require a clear line-of-sight path between the transmitter and receiver. This means that FSO systems are not suitable for communication in environments with significant obstacles or in situations where the transmitter and receiver are not in direct view of each other. Additionally, FSO systems are vulnerable to atmospheric conditions such as fog, rain, and snow, which can absorb or scatter the transmitted light and disrupt the communication.
Overall, FSO communication is a promising technology that offers high bandwidth and low cost, but it is not suitable for all communication scenarios. It is important to carefully consider the specific requirements of a communication system and the environment in which it will be used before deciding whether FSO communication is the right choice.
FSO Communication
There are three effects on turbulence: scintillation, laser beam spreading and laser beam wander. These LCTs make over 60 satellite-to-satellite links over a distance of 45,000 km per day and have logged over 30,000 links total. It offers the speed of fiber with the flexibility of wireless. Aerospace and Defense 8. Alexander Graham Bell: Giving Voice To The World. In this part, we used design 2 as demonstrated in Figure 18.
With an appropriate design of aperture averaging, the received optical power could be increased and the effect of the scintillation can be dumped. Atmospheric Effects on Optical Wireless Links Presented at 7th International Conference on Telecommunications ConTEL , pp. Therefore in foggy areas, Free Space Optics may not be the best solution, however applications have been successfully carried out that have provided acceptable reliability with redundancy systems in place. The point where the light converges is called the focal point and the distance between the lens and the focal point is called focal length. Close to ground, there is the largest gradient of temperature associated with the largest values of atmospheric pressure and air density. The effect of Clear Atmospheric Turbulence on the Quality of the Free Space Optical Communications in Yemen.
Unfortunately such links are highly susceptible to atmospheric effects. Several entities are continually attempting to overcome these key disadvantages to FSO communications and field a system with a better Other non-government groups are fielding tests to evaluate different technologies that some claim have the ability to address key FSO adoption challenges. Key Subsidiaries or Distributors 16. Click here to view the FSO Technology Shift Zone — a timeline and market growth graphic showing FSO technology adoption. Military FSO or Laser Communications Spectrum congestion is a growing problem, it increasingly limits operational capabilities due to the increasing deployment and bandwidth of wireless communications, the use of network-centric and unmanned systems, and the need for increased flexibility in radar and communications spectrum to improve performance and overcome sophisticated countermeasures. Practical part, we take the climate effects for deployment of FSO in Yemeni territorial as a case study.
When these are considered to be random and dense enough that their individual effects average out, this kind of scattered reflection is commonly referred to as diffuse reflection. Free Space Optics FSO Communication Market Analysis By Industry Vertical 8. If we want an acceptable communication BER of 10 —9, the maximum link range between transmitter and receiver should be about 1600 m for 850 nm, 1900 m for 1000 nm, and 2500 m for 1550 nm. Market Attractiveness Analysis, By Industry Vertical 9. GA-ASI Successfully Tests Air-To-Space Laser Communication System General Atomics Aeronautical Systems, Inc. Open Access is an initiative that aims to make scientific research freely available to all.

Is easily upgradeable, and its open interfaces support equipment from a variety of vendors, which helps enterprises and service providers protect their investment in embedded telecommunications infrastructures. Diverging lenses are thinner across their middle and thicker at their upper and lower edges. This contrasts with using solids such as optical fiber cable or an optical transmission line. Light scattering is a form of scattering in which light is the form of propagating energy which is scattered. While many companies are within range of fiber-optic cable, most are not adequately connected as a result of prohibitive licensing requirements and the expense of having to dig up streets and neighborhoods. In 2018, the global Free Space Optics FSO and Visible Light Communication VLC market size was million USD and it is expected to reach million USD by the end of 2025, with a CAGR of % during 2019-2025.
Market Attractiveness Analysis, By Range Type 7. Rain and snow have little effect on FSO technology, but fog is different. Archived from PDF on 2015-04-26. We can see, anything that can be done in fiber can be done with FSO. Note you can select to save to either the free. The information used to estimate market size, share, and forecast of various segments-sub segments at the global, country level, regional level is derived from the unique sources and the right stakeholders. Simulation results of BER and SNR The data was taken from the Civil Aviation and Meteorology Authority and the Yemeni Meteorological Service.

Key Subsidiaries or Distributors 16. The transmitter, which consists of two part main parts: an interface circuit and source driver circuit, converts the input signal to an optical signal suitable for transmission. This work was concentrated on two different designs as demonstrated in We concentrate on the scintillation effects on the performance of FSO links. That means the effect of the turbulence is too small contrary to visibility and geometric loss. Proceedings of SPIE; 2002.

Limiting Resolution Down Through the Atmosphere. Copper technologies may ease some short-term pain, but the bandwidth limitations of 2 megabits to 3 megabits makes them a marginal solution, even on a good day. Lower power telecommunications grade lasers operating typically between 1280-1310 nm are commercially available. This loss is a fixed value for a specific FSO deployment scenario; it does not vary with time, unlike the loss due to rain attenuation, fog, haze or scintillation.
