Leading a New Future with Fiber: YOFC at MWC Barcelona 2025

On March 3, 2025, the global communications and technology landscape gathered in Barcelona for the highly anticipated MWC Barcelona. Among the standout participants was Yangtze Optical Fibre and Cable Joint Stock Limited Company (YOFC), showcasing their visionary theme, "Leading a New Future with Fiber." The company displayed innovative products and solutions across five key scenarios: 5G Advanced Connectivity, Intelligent Computing Centers with AI, Energy Internet, Smart Traffic, and Digital Life Enjoyment.

Advanced 5G Connectivity Framework

As the demands for 5G-A and 6G communication continue to evolve, YOFC highlighted several key innovations including the G.654.E optical fiber, which is renowned for its long-distance transmission capabilities, ultra-fast speed, and high capacity. This fiber stands out in the industry for its combination of large effective area and low attenuation coefficient, making it a preferred choice for ultra-high-speed technologies currently at the forefront, such as 400G and 800G, and future 1 Tbps transmission technologies.
For over a decade, YOFC has pioneered the development of G.654.E fiber technology, successfully implementing these fibers on a large scale in network infrastructure projects with major Chinese operators and telecommunications companies in countries like the Philippines and Brazil.

To contribute further to advancements in optical communication technologies, YOFC premiered two cutting-edge products at MWC:

• - EasyBand® Plus-Mini 173µm Fiber: This innovative fiber combines a smaller outer diameter with bend resistance, effectively reducing the size and weight of fiber optic cables, enhancing resource utilization, making it ideal for upgrading urban pipe networks.
• - MaxBand® OM4 Pro Fiber: Specifically designed for 100 G single-channel transceivers, this product mitigates signal degradation caused by variations in central wavelength in optical modules, facilitating the smooth transition from multimode connectivity solutions in data centers to 400 G, 800 G, and beyond.

Ultra-fast Optical Fibers for Intelligent Computing Centers Powered by AI

Focusing on AI-driven data center scenarios, YOFC introduced its intelligent computing solution, incorporating advanced optical fibers, including hollow-core and multimode variants. Coupled with 400G/800G optical modules and eco-friendly cabling, these technologies significantly enhance computing power while promoting sustainability, guiding the industry toward a greener future. The hollow-core fiber, often referred to as a disruptive technology for next-gen optical communication, offers a 34% reduction in transmission delay compared to traditional solid fibers, providing a high-performance pathway for intelligent computing networks and large-scale distributed models.

Leveraging years of expertise and technical know-how in mass-producing cables and fibers, YOFC remains at the forefront of manufacturing long-haul hollow-core fibers with ultra-low loss characteristics (<0.1 dB/km). This positions the company to offer premium products for a wide array of commercial applications.

Marine Communication Solutions for a Sustainable Future

During the exhibition, YOFC displayed an extensive range of underwater optical fiber cables, both with and without repeaters, along with their proprietary line of marine repeaters equipped with junction boxes. YOFC's underwater fiber optic cables are engineered to tackle the challenges posed by diverse underwater environments, with maximum installation depths reaching 8,000 meters. The complete series has obtained full UJ/UQJ certifications.

In addition, YOFC showcased subsea composite power cables rated at 220 kV AC, 500 kV AC, and 330 kV DC, tailored for high-power transmission between the mainland and islands, facilitating the transmission of clean energy. The company is well-equipped with cable laying vessels, crane vessels, and turbine installation ships, enabling them to offer flexible solutions and comprehensive professional services to customers.

Smart Optical Vehicle Solutions Redefining Travel Experience

Introducing the pioneering concept of a "fully optical smart vehicle," YOFC's vehicle intelligent solution enhances vehicle electrification and intelligence while increasing safety, reliability, and reducing both energy consumption and maintenance costs. These advancements are made possible through the integration of five new optical fiber communication technologies within the vehicle, including light-emitting optical fiber integrated into the windshield, erbium and ytterbium doped fibers for LiDAR amplifiers, battery monitoring through fiber, and silicon carbide components.

Furthermore, YOFC unveiled their latest communication solutions tailored for urban rail transport, addressing wireless coverage challenges in communications systems that operate within a railway network or among collaborative rail networks. These solutions aim to ensure "zero blind spot" communication security for urban rail transportation.

FTTx Solution for Enhanced Fiber Connectivity

YOFC's FTTx solution provides a comprehensive end-to-end package that includes optical fiber, equipment, connectors, and a full suite of services, assisting customers in quickly deploying fiber access networks. The next-generation FTTR (Fiber to the Room) fully optical network solution seamlessly extends 10 Gbps bandwidth to every corner using invisible fiber cabling. This solution supports simultaneous access from various types of terminals, making it ideal for scenarios such as 8K Ultra HD video streaming, cloud gaming, and comprehensive smart home intelligence.

Simultaneously, YOFC's high-quality connectivity products and solutions, including HDMI, DP, USB, and audio cables, have achieved remarkable technological advancements, transitioning from fiber to home to fiber directly to the display. This ensures that every connection, whether for home audiovisual applications or engineering-grade applications, exceeds expectations, delivering a seamless and limitless experience.

From “Channeling” to “Ecosystem” in Optical Communication

"In the AI era, optical fiber transcends its role as an information conduit to become the brain of an intelligent ecosystem," stated Zhuang Dan, CEO and Chairman of YOFC. "Our participation in MWC underscores YOFC's ongoing commitment to leverage optical fiber technology to drive network upgrades, enhance computational efficiency, and promote sustainable growth through collaboration with global partners."

As a leader in the global optical communications sector, YOFC consistently positions itself at the forefront, dedicated to transforming fiber optic technology from a mere "information transmission channel" into a "facilitator of the AI ecosystem." Staying true to the corporate mission of "Smart Link Better Life," YOFC maintains a customer-focused and innovation-driven approach, continuously pushing the boundaries of value in optical communications and endeavoring to realize the limitless potential of a smart world.
