Terrestrial Free Space Optical (FSO) Communication Market Trends

SWIR Driving Evolution of Free Space Optical (FSO) Communication

Free Space Optical (FSO) communications rely heavily on the quality and reliability of transmitted signals. But due to the limitations of FSO communication, such as obstruction of signal transmission due to weather effects such as fog, rain, and snow. Moreover, challenges such as atmospheric conditions, including dust, water vapor, scintillation, scatter light and degrade the overall signal quality. Therefore, there is a growing trend in the integration of FSO systems with Short-Wave Infrared (SWIR) cameras, which offer several key benefits, making them a suitable choice for high-quality data transmission. With the integration of SWIR, FSO technology leverages the specific properties of SWIR land-based lasers, such as penetration of environmental obstacles, such as fog and dust. For instance, Xenics, a leading Exosens brand, offers the Cheetah+ series, a high-speed SWIR camera specifically designed for advanced Free Space Optical (FSO) communication systems.

Market Dynamics

Market Drivers

Rise in Demand for High Bandwidth and High Speed Connectivity to Boost Market Expansion

The increase in data consumption across various sectors such as telecommunications, enterprise IT, cloud computing, video streaming, and others has driven the need for high bandwidth and high-speed communication structures. With the rise in installation of applications that work on an extensive amount of data, there is also an increase in pressure on existing network systems to deliver faster and more reliable data transmission continues to grow.

Terrestrial Free Space Optical (FSO) Communication systems are well-suited to address this demand as they are capable of delivering gigabit-per-second (Gbps) data rates, as compared to fiber optics networks. Unlike traditional wired systems, FSO uses laser-based optical transmission through air, enabling a high-capacity data transfer without the need for physical cables. All these factors are expected to create Terrestrial Free Space Optical (FSO) Communication as a suitable solution for applications such as last-mile connectivity, enterprise communication, and others.  

Market Restraints

Atmospheric Interference Due to Weather Conditions and Turbulence to Hinder Market Growth

One significant restraint to Free Space Optics (FSO) is the atmospheric interference created by obstacles such as fog, rain, and dust. FSO systems are reliant on the transmission of light beams through the atmosphere to enable high-speed data communication. Obstacles such as fog, rain, snow, and even strong winds can scatter or absorb the optical signal, decreasing its intensity and potentially causing data loss or link failure. Temperature and pressure variations create turbulent eddies that distort the optical beam, causing fluctuations in signal strength (scintillation) and making it difficult to maintain a consistent connection. Therefore, such disadvantages are expected to hamper the Terrestrial Free Space Optical (FSO) Communication market growth in the coming years.

Market Opportunities

Adoption of Free Space Optics for 5G Backhaul/Fronthaul to Drive Growth Opportunities

Due to the rise in use of data-intensive applications, there is a need for communication technology to enable faster data speeds and lower latency. 5G is well-positioned to support such use cases that need continuous high-speed communication or rely on fast data transfer. Free Space Optics (FSO) is a technology that can be used for both backhaul and fronthaul in wireless communication networks, particularly in 5G and beyond. Free Space Optics (FSO) technology provides high bandwidth and is less likely to experience interference issues as compared to traditional radio frequency (RF) solutions.

Market Challenges

Lack of Standardization Poses a Significant Challenge for Market

The market still has no widely adopted single universal industry standard. This leads to compatibility issues between vendors and makes integration with existing telecom infrastructure more complex.  FSO systems must comply with laser safety standards, which are categorized by wavelength and power density. Moreover, there is a need for the establishment of regulatory standards so that multiple Terrestrial Free Space Optical (FSO) communications can work together without creating interference among each other. Thus, the lack of standardization in the terrestrial segment of the global free space optical communication industry is expected to bring challenges for the growth of the market.
