Let’s think of the last time you sent data without wires. We’re not talking WiFi here, but plain optical signals. Free-space optical communication, or FSO, is an interesting and easy way to transmit ...

Digital pre-compensation techniques have emerged as a pivotal tool in modern optical communication systems, addressing the challenges posed by nonlinearity and other system impairments. These methods ...

Free-space QSDC does not require the laying of optical fibers, which can effectively prolong the transmission distance and break the limitation of terrain. It is one of the solutions to the "last mile ...

Four parties will verify bidirectional communication by equipping optical wireless communication devices on Low Earth Orbit satellites and HAPS. The National Institute of Information and ...
