Abstract: Free-space optical communication (FSO) can achieve fast, secure and license-free communication without need for physical cables, making it a cost-effective, energy-efficient and flexible solution when the fiber connection is unavailable. "Free space" means air, outer space, vacuum, or something similar. What is FSO (Free Space Optics)? FSO is a wireless technology that transmits data through laser beams. It uses light waves to transmit data between buildings with. As the demand for high-speed, low-latency communication continues to grow, free-space optical (FSO) communication has gained prominence as a promising solution for supporting the next generation of wireless networks, especially in the context of the 5G and beyond era. Here we report a platform combining multiple transmission media of 40-km single-mode fibre, with 1.
