China has developed a satellite system that can transmit data at speeds five times faster than Starlink using a 2-watt laser from an orbit over 36,000km high. The technology, called AO-MDR synergy, uses adaptive optics to sharpen distorted light and mode diversity reception to capture scattered signals. This method allows for data transmission in under five seconds, despite atmospheric turbulence that typically distorts signals. Led by researchers from Peking University of Posts and Telecommunications, the breakthrough could enable faster-than-light connections between distant locations.
