Innovations Set New Benchmarks in Optical Communications
Yangtze Optical Fibre and Cable Joint Stock Limited Company (YOFC) unveiled significant advancements in hollow-core fibre technology at the OFC Conference held at San Francisco’s Moscone Center from March 30 to April 3, 2025.
During a workshop titled “How will future submarine systems look like,” Dr. LUO Jie, YOFC’s Chief Technology Officer, presented the company’s latest achievements. YOFC has successfully reduced attenuation to a record-low of 0.05dB/km and extended the manufacturing length of single fibres to over 20 kilometers. These advancements were demonstrated through a 21.7 km long hollow-core fibre with a proprietary supporting tube structure (ST-HCF), drawing considerable attention for its potential impact on optical communications.
Hollow-core fibre technology, which allows light to be transmitted through an air core, offers a 47% increase in transmission speed and a 31% reduction in latency compared to conventional fibres. This technology is poised to revolutionize data transmission in applications such as data centers, AI models, and financial trading. Additionally, its low attenuation and nonlinearity could address capacity bottlenecks in submarine communication networks and long-distance terrestrial communication lines.
“Revolutionizing Optical Communications with Hollow-Core Fibre Technology”
Dr. LUO Jie emphasized the practical and theoretical enhancements that hollow-core fibres could bring to submarine cable systems, highlighting their ability to increase data throughput and reduce transmission times.
YOFC continues to lead in hollow-core fibre technology development, leveraging its research capabilities to overcome industrial challenges. As the digital economy grows, YOFC’s innovations are set to play a crucial role in supporting the evolution of global digital infrastructure.
