Free-Space Optical Communication (FSOC) technology is offering secure, high-throughput data transfer that is faster than RF with minimal risk of interception or jamming. These characteristics are highly desirable in defence settings, especially for satellite-based and space-to-ground communication. However, FSO is not yet ready to operate as a stand-alone system in defence, primarily due to its limitations in atmospheric conditions such as fog, rain, turbulence, and alignment challenges. This technology thrives in the vacuum of space, but the operational complexity in atmospheric and terrestrial environments has restrained its real-world deployment.
FSOC technology holds a significant promise as part of a hybrid communication system alongside RF, acting as a complementary channel in environments with high electronic warfare activity or when spectrum congestion is high.
Our new study, "Free-Space Optical Communication (FSOC) - Market and Technology Forecast to 2033", explores FSOC’s potential to transform defence communications. Our research tests the waters for its viability in military environments, where the stakes are far higher and the challenges far more complex.
This study highlights several critical insights shaping the trajectory of FSOC technology in defence and beyond. First, while interest and experimentation are steadily rising, the window for full-scale defence deployment remains limited within the current forecast period (2025–2033). Most activity is currently concentrated in prototypes, pilot programs, and testbeds, with large-scale rollouts unlikely until key technical and environmental challenges are resolved.
A major takeaway is the hybrid potential of RF-FSOC systems, which are emerging as the most viable path forward for battlefield communications. These systems offer both the speed and stealth of optical links and the reliability of RF fallback, enabling mission-critical redundancy in environments where weather or physical movement might otherwise disrupt communication.
The current stage of FSOC’s evolution is largely research-driven, with significant contributions from organisations like DARPA (US), ESA (Europe), and the Netherlands’ defence programmes. These bodies are pushing the boundaries through experimentation in adaptive optics, terminal miniaturisation, and ruggedised platforms. Their progress is essential to moving the technology from lab-based prototypes into field-ready systems.
From a market perspective, we do not anticipate widespread commercialisation or adoption before the end of this decade. The technology still requires refinement in atmospheric compensation, beam-tracking, and hardware durability, particularly for military and space applications. However, once these barriers are overcome, the scalability of FSOC systems will dramatically improve.
Despite its gradual pace, FSOC technology represents a significant long-term investment opportunity. Its potential to reshape secure communications across space, air, land, and sea makes it a “golden business opportunity” for forward-looking investors, OEMs, and startups. Those who invest now stand to gain early-mover advantages in what could become a foundational technology in next-generation defence and space communication ecosystems.
