Researchers from China Telecom, ZTE and Yangtze Optical Fibre and Cable tested a new hollow-core fibre over more than 1,000 km, cutting transmission delays by 30% at 64 terabits per second.
- Traditional fibre slows light through solid glass; hollow-core fibre lets light travel mainly through air, close to its maximum speed
- Moving huge volumes of data between data centres is a key AI bottleneck, and faster interconnects could ease it
- Notable shift: while the world races on AI chips, this work targets the optical interconnect layer
