Enhancing Global Digital Infrastructure: Insights from YOFC at MWC25

On March 6, 2025, the Tower and Fibre Summit took place at the Barcelona International Convention Centre, sponsored by Yangtze Optical Fibre and Cable Joint Stock Company (YOFC). Jan Bongaerts, the Senior Vice President of YOFC, delivered a keynote speech entitled "Leading a New Future with Fibre". In his address, Bongaerts emphasized YOFC's commitment to leveraging cutting-edge technologies and global industry expertise to enhance digital infrastructure in the age of artificial intelligence (AI).

Bongaerts discussed the exponential growth of global data traffic, which is heavily influenced by the deep integration of AI technology across various sectors. He pointed out that demand for higher network transmission rates, increased capacity, and reduced latency is being driven by advancements such as generative AI applications, ultra-high-definition video streaming, autonomous driving, and industrial internet applications. To meet these needs, YOFC revealed innovative next-generation optical fibre solutions specifically designed for high-speed, high-density, and low-latency scenarios, which are essential for the development of a robust global digital infrastructure.

The G.654.E fibre showcased by YOFC significantly enhances the performance and reach of high-speed transmission systems operating at 400G/800G. As one of the few entities globally capable of mass-producing this technology, YOFC maintains complete control over its entire industrial chain, positioning itself as a leader in both production capacity and market share. This revolutionary fibre has already become integral to the network infrastructure projects of major operators such as China Mobile, China Telecom, China Unicom, and State Grid, with deployment efforts ongoing in several countries, including the Philippines and Brazil.

In response to the increasing demand for high-speed and short-distance interconnections within AI data centers, YOFC has launched its premium multimode fibres, OM4/OM5. These state-of-the-art fibres support a wider wavelength spectrum and higher bandwidth, catering to the evolving needs of data centers looking to advance toward 400G/800G and even 1.6T transmissions. Thanks to its digital and intelligent manufacturing platform, YOFC can produce high-quality premium multimode fibres at scale, further solidifying its leadership position in the global market.

As the era of AI continues to advance, the interconnection of massive devices has intensified the demand for maximizing the efficiency of fibre space. YOFC's exclusive multicore fibre addresses this requirement by integrating several independent cores within a single fibre. This innovation tremendously increases the transmission capacity of single-fibre communication systems, potentially multiplying it by several times and offering promising solutions to the capacity bottlenecks faced by future optical communication systems.

Furthermore, the hollow-core fibre, with transmission speeds approaching that of light and nearly zero latency, presents an optimal choice for future high-speed, low-latency communications. YOFC’s capabilities in the mass manufacturing of long-length hollow-core fibre with extremely low loss are at the forefront of the industry. This positions the company well to provide high-quality products suitable for large-scale commercial applications.

In the context of the rapid advancement of AI and digital technologies, YOFC remains at the forefront, with innovation as its cornerstone. The company is committed to partnering with global leaders to develop a more efficient, sustainable, and inclusive optical communication network. YOFC aims to lay new foundations for AI and substantially advance global digital transformation.
