The internet has never been this fast: downloading 20,000 movies in 1 second

Chinese researchers have achieved a new data transmission record of 3.2 petabits per second using a 24-core optical fiber, marking a 30% improvement over their previous record. This speed allows for simultaneous gigabit internet access for 3.2 million households. The technology utilizes spatial multiplexing and combines three wavelength bands to transmit data efficiently. While this advancement is significant for backbone networks, it is not yet applicable for home internet connections due to the need for further infrastructure development. The technology is expected to first benefit data centers and high-performance computing systems.
