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.
