YOFC Showcases Hollow-Core Fiber Innovations Promising Faster Data Transmission
Barcelona, Tuesday, 1 April 2025.
YOFC unveils hollow-core fiber technology reducing signal attenuation to 0.05 dB/km, boosting transmission speed by 47%, and cutting latency by 31%, setting new benchmarks in optical communications.
Breakthrough in Fiber Technology
At the OFC Conference in San Francisco’s Moscone Center, running from March 30 to April 3, 2025, YOFC demonstrated a significant leap forward in optical communication technology. The company showcased a 21.7-kilometer hollow-core fiber featuring a proprietary supporting tube structure (ST-HCF), achieving a record-breaking attenuation of just 0.05dB/km [1]. This development marks a substantial improvement over traditional solid-core fibers, particularly in addressing the growing demands of data-intensive applications.
Performance Metrics and Applications
The revolutionary hollow-core design enables light transmission through an air core, delivering a 47% increase in transmission speed and a 31% reduction in latency compared to conventional fibers [2]. These improvements are particularly crucial for applications demanding rapid data transmission, including data centers, AI models, and financial trading platforms [1]. The technology’s exceptionally low attenuation and nonlinearity characteristics position it as a potential solution for addressing capacity constraints in submarine communication networks and long-distance terrestrial communication lines [3].
Global Implementation and Market Impact
YOFC has already begun implementing this technology in real-world applications, with the world’s first 800G hollow-core fiber test network deployed in southern China in 2024 [3]. The company is actively expanding its global reach, with plans to introduce this technology in Brazil and the Philippines for trunk line upgrades [3]. With eight production bases across six countries and over 9,300 employees, YOFC is strategically positioned to drive the adoption of this technology worldwide [3].
Future Outlook and Development
Looking ahead, YOFC plans to initiate mass production of these low-signal-loss hollow-core fibers for commercial applications [3]. The company’s commitment to innovation is evidenced by its publication of 15 research papers at OFC 2025 [4], demonstrating ongoing collaboration with global operators, universities, and research institutes. This technological advancement is poised to play a crucial role in supporting the evolution of global digital infrastructure, particularly as demands for faster, more efficient data transmission continue to grow [1].
