Yangtze Optical Fibre and Cable Joint Stock Limited Company (YOFC) (stock tickers: 601869. SH, 06869.HK) has unveiled significant advances in hollow-core fibre (HCF) technology at the OFC Conference 2025, held from March 30 to April 3 at the Moscone Center, San Francisco. The announcement positions YOFC at the forefront of next-generation optical communication solutions.
During a high-profile workshop titled “How Will Future Submarine Systems Look Like?”, Dr. LUO Jie, Chief Technology Officer of YOFC, showcased cutting-edge progress in HCF development. His presentation highlighted a world-record attenuation rate of just 0.05 dB/km and manufacturing lengths exceeding 20 kilometers—milestones that surpass traditional solid-core fibre performance.
These achievements were demonstrated through a 21.7 km long hollow-core fibre featuring YOFC’s proprietary Supporting Tube Hollow-Core Fibre (ST-HCF) structure, drawing considerable attention from researchers, industry leaders, and policymakers alike.
A Paradigm Shift in Optical Communications
Hollow-core fibre, which transmits light through an air core rather than glass, marks a revolutionary shift in optical network design. YOFC’s latest advancements facilitate:
47% faster transmission speeds
31% lower latency
Reduced nonlinearity and attenuation
These characteristics make HCF ideal for data centers, high-frequency trading, AI computing, and submarine communication systems, which demand ultra-low latency and high-speed connectivity.
Future-Proofing Global Infrastructure
In his talk, Dr. LUO Jie underscored the transformational potential of HCF in submarine cable systems, particularly in boosting bandwidth capacity and minimizing signal delay. He also elaborated on the practical and theoretical innovations that YOFC has implemented to overcome the historical challenges of hollow-core fibre production and deployment.
“YOFC’s new-generation hollow-core fibre is not just a technological achievement—it’s a cornerstone for the future digital economy,” said Dr. LUO. “By reducing latency and increasing bandwidth, we are laying the foundation for a faster, more efficient global communications infrastructure.”
Industry Leadership and Vision
YOFC’s breakthroughs stem from its robust research ecosystem, including a self-developed raw material system and world-class fabrication techniques. These capabilities allow the company to push boundaries in optical material science, design, and manufacturing.
As demand for next-generation digital infrastructure grows, YOFC continues to drive innovation in fibre-optic technology, ensuring the global network backbone remains agile, scalable, and prepared for the data-intensive world of tomorrow.
