The National Institute of Information and Communications Technology (NICT) in Japan achieved the new internet speed record of 402 terabits per second using standard optical fiber cables3. This breakthrough demonstrates the potential of space division multiplexing (SDM) fibers with standard cladding diameter and compatibility with existing cabling technologies for near-term adoption of high-throughput SDM fiber systems.
The new record for internet speed, set by an international team from the National Institute of Information and Communications Technology, is 402 terabits per second, which is a 25% increase from the previous record6. This achievement was made using 30 miles of commercial fiber-optic cables and signal amplifiers.
