Chinese fiber optic cable industry

The Chinese fiber optic cable industry deeply empowers industrial upgrading through technological innovation. At the technical level, breakthroughs have been made in hollow fiber and quantum secure communication technology to achieve ultra-low loss and ultra-high speed transmission. For example, China Telecom has completed a 101.6-kilometer hollow fiber experiment with a transmission capacity of 37.6Tbps; The quantum secure communication ring network covers the Yangtze River Delta, Beijing Tianjin Hebei region, ensuring information security. The manufacturing end is deeply integrated with 5G, AI and industrial Internet. Hengtong Group and others have built a national intelligent manufacturing demonstration factory and a 'lighthouse factory' to promote personalized customization, flexible production and full process digital control, and the efficiency of human-machine collaboration has increased by more than 30%. The application is expanded to include computing power networks, 6G, and integrated communication of air, space, earth, and sea, supporting millisecond level latency requirements for data center interconnection, finance, power, and other scenarios. Standardization and ecological construction are advancing simultaneously, and 800G/1.6T ultra high speed optical transmission has become a research hotspot. The industry is reshaping the value of the industrial chain through technological breakthroughs, and consolidating the 'carrier base' of new infrastructure.
