YOFC Advances Hollow-Core Fiber Technology for Faster Data Transmission
San Diego, Thursday, 3 April 2025.
At OFC 2025, YOFC introduced hollow-core fibers with a record low attenuation of 0.05 dB/km, boosting transmission speeds by 47% and lowering latency by 31%.
Breakthrough in Fiber Manufacturing
YOFC has achieved a significant milestone by extending the manufacturing length of individual hollow-core fibers to over 20 kilometers, demonstrating this capability with a 21.7 km fiber featuring a proprietary supporting tube structure (ST-HCF) [1]. This advancement represents a crucial step toward commercial viability, as the technology enables light transmission through an air core rather than traditional solid glass [2].
Applications and Market Impact
The implications for data centers, AI models, and financial trading are substantial, with the technology showing particular promise for submarine communication networks and long-distance terrestrial lines [2]. During the OFC Conference presentation, Technical Director Dr. LUO Jie highlighted how these advancements could transform submarine cable systems, emphasizing enhanced data throughput and reduced transmission times [1]. The company’s commitment to innovation was further demonstrated at MWC Barcelona 2025, where YOFC showcased its Smart Computing Solution, integrating hollow core and multi-core fibers with 400G/800G optical modules [3].
Future Development and Global Implementation
YOFC’s expertise extends beyond research and development, with the company successfully mass-manufacturing ultra-low-loss hollow core fibers (<0.1 dB/km) for commercial applications [4]. The technology’s potential is particularly evident in submarine communication solutions, which can operate at depths of up to 8,000 meters [4]. Senior Vice President Jan Bongaerts has emphasized that hollow-core fiber technology, with its near-zero latency and transmission speeds approaching the speed of light, represents the optimal choice for future ultra-high-speed communications [5].
