Group 1 - A team of Chinese scientists has achieved significant breakthroughs in the fields of 6G and optical communication, marking the first international realization of seamless integration between fiber optic and wireless communication systems [1] - The results, published on February 19 in the journal Nature, indicate that the system has set three world records: a modulator bandwidth exceeding 250GHz, a single fiber capable of transmitting 512Gbit of data per second, and wireless transmission reaching 400Gbit per second [1] - All key technologies and fabrication processes for these achievements are based on a fully domestic integrated optics platform, which supports China's goal of "leapfrogging" in the semiconductor chip sector [1]
