YOFC's Innovations in Hollow-Core Fiber Technology

The recent OFC Conference, held from March 30 to April 3, 2025, at the Moscone Center in San Francisco, showcased profound advancements by the Yangtze Optical Fibre and Cable Joint Stock Limited Company (YOFC) in hollow-core fiber technology. During a workshop titled "What Will Future Submarine Systems Look Like?" Dr. LUO Jie, YOFC's technical lead, revealed remarkable developments that set new industry standards.

A primary highlight of YOFC's session was the achievement of an unprecedented attenuation level of just 0.05 dB/km, coupled with an impressive extension of single-fiber production lengths exceeding 20 kilometers. These breakthroughs surpass conventional full-core fibers significantly, as illustrated by the company’s demonstration of a 21.7-kilometer hollow-core fiber incorporating an innovative support tube structure (ST-HCF). The demonstration garnered considerable attention at the event, hinting at transformative implications for optical communication.

Hollow-core fiber technology signifies a paradigm shift in optical communication, facilitating the transmission of light through an air core rather than a solid medium. This unique design propels transmission speeds by 47% and slashes latency by 31% compared to traditional glass fibers. Such enhancements underscore the technology's potential applicability in sectors demanding rapid and efficient data transfer, notably in data centers, artificial intelligence models, and financial trading environments. Moreover, the extraordinarily low attenuation and nonlinearity characteristics of this technology may effectively alleviate capacity bottlenecks prevalent in underwater communication networks and terrestrial long-distance lines.

In his presentation, Dr. LUO Jie explored the theoretical and practical advantages that hollow-core fibers could bring to submarine cable systems, emphasizing their capability to boost data throughput while reducing transmission times in future deployments. These enhancements could be pivotal as digital demands surge across global infrastructure.

YOFC is spearheading the development of hollow-core technologies, leveraging its extensive research capabilities and autonomous raw materials research system to tackle significant industrial challenges. With the ongoing growth of the digital economy, YOFC's relentless innovation in hollow-core technology is poised to become crucial in shaping the future of global digital infrastructure, ensuring it remains robust, efficient, and capable of meeting coming demands.

In summary, the advancements presented by YOFC at OFC 2025 spotlight the exciting future of optical communication powered by cutting-edge hollow-core fiber technology. As the fabric of modern digital infrastructure continues to evolve, YOFC is well-positioned to lead the way, not only setting new benchmarks in performance but also redefining how we connect and communicate worldwide.
