Cailabs leads the way in space optical communication, driving the future of high-speed satellite data transmission
In 2023, NASA reached a significant milestone in space communication, and it remained historically the highest rate of data transmission ever means of optical technology. NASA sent back to Earth 200 gigabits per second from a satellite in space as it reached a record speed that enabled the agency to send 3.6 terabytes in just six minutes. This marks the potential of optical communication, using lasers rather than the traditional radio frequencies to transfer faster and more secured data.
The novelty of NASA's first successful laser-based data transfer experiment has sparked the interest of many companies to engage in optical communications. Among them is Cailabs, a young French startup that evolved from being a leader in fiber optics to becoming a pioneer in aerospace optical communication technology. In 2019, a client offered Cailabs the opportunity to enter the field of optical communication by suggesting they adapt their telecom technology for space applications.
Success arrived in the form of a contract from the French Ministry of Defense where it teamed with another firm to achieve for the first time high-speed optical communication between a nano-satellite and a commercial ground station. The system is to overcome the traditional limitation of radio frequencies, allowing quicker, more secure transmissions that are harder to detect and interfere with.
Although Cailabs, despite facing initial problems and having a very low interest level, has managed to mark its identity in the aerospace field today. It conceives designs and develops ground stations for satellite-based optical communication with seven operational systems already. When the demand for high-speed space communications will gain pace, the company will be of much importance in this technology.
Experts believe that in the near future, not too long from now, optical communication will have become a standard for satellite operations and will bring tremendous improvements regarding the sending of real-time data, especially in health monitoring or internet services. However, Cailabs's main competition is from industry giants such as Airbus or Safran, which have more resources at hand, but which are less agile to adapt to the fast-moving speed of this market.
