Chinese Team Launches 3-Band Fiber System, Lifting Data Capacity More Than 5-Fold

1 articles · Updated · AS USA · Jun 14

Summary

  • Qingdao now hosts what the report describes as the first commercial “three-lane” fiber-optic system, using S, C and L spectrum bands in parallel to carry more than five times current traffic on existing cable.
  • The capacity jump comes from stabilizing the noise-prone S-band and combining multiple cores inside a single fiber, creating parallel data paths without laying a new network from scratch.
  • Unlike earlier lab records in Japan, Europe and the United States, the Chinese deployment is operating infrastructure linking data centers and serving as a test bed for next-generation networks.
  • AI training demand is straining current networks, making higher-capacity fiber a strategic upgrade as data-hungry computing expands.
