News & Events

On September 9, the 27th China International Optoelectronic Exposition (CIOE 2026) opened with great fanfare at the Shenzhen World Exhibition and Convention Center. Yangtze Optical Fibre and Cable Joint Stock Limited Company (YOFC) made a high-profile appearance under the theme "Leading the AI Era: Connecting to a Green Future." On opening day, the YOFC booth drew huge crowds, as industry experts, partners, and professional visitors gathered to engage in in-depth discussions on the innovation and real-world deployment of optical communication technologies in the AI era.

AI Computing Hub:

Building a Robust All-Optical Foundation for the Intelligent Computing Era

Addressing the extreme bandwidth and latency requirements of large AI model training and intelligent computing center interconnection, YOFC presented on site a complete AI computing hub solution spanning fibre, optical transceivers, and cabling solutions. The anti-resonant hollow-core fibre, with attenuation as low as 0.04 dB/km, continuous lengths of more than 91 kilometers on a single fibre, and the world's leading scale of commercial delivery (over 10,000 fibre-kilometers in total), became a focal point of the booth; multi-core fibre effectively saves data hall space, while G.654.E fibre and premium multimode fibre meet the needs of trunk transmission and 800G/1.6T high-speed interconnection scenarios respectively. Also on display were 1.6T optical transceivers and iCONEC's next-generation intelligent computing center cabling solutions, covering full-scenario needs from distribution and backbone to equipment patch cords. At the booth, YOFC joined forces with EXFO to present a hollow-core fibre testing solution, which drew wide attention.

Fibre Solutions for CPO Applications:

Leading Next-Generation Optical Interconnect Technology

The surge in AI computing power is accelerating the deployment of co-packaged optics (CPO)/near-packaged optics (NPO), leaving light-source links to face the dual challenges of polarization stability and efficient coupling. On site, YOFC presented its paired fibre product solution—the Prime series pairing polarization-maintaining (PM) fibre with single-mode fibre, developed specifically as matched pairs for CPO/NPO optical-engine fibre array units (FAUs). The PM fibre and single-mode fibre deliver an upgraded mode-field match, with significantly enhanced long-term reliability. From the first PM fibre mass-produced in China to a full PM fibre portfolio, YOFC leverages fully independent, end-to-end capabilities to safeguard AI optical interconnect from light source to engine with ultimate precision and stability.

Specialty Products and Solutions for Fibre Sensing:

Enabling Precise Sensing in Extreme Environments

From oil wells ten thousand meters deep to the deep blue sea, and from UHV valve towers to energy storage systems, YOFC exhibited a range of specialty fibre and cable products in the flesh, covering three major scenarios. In oil and gas exploration, the high-temperature carbon-coated fibre resists extreme heat and hydrogen exposure, while the triple-sealed downhole cable withstands corrosion and high pressure. In underwater detection, the bend-insensitive fibre adapts to confined spaces, the watertight cable withstands hydrostatic pressure and repeated deployment and retrieval, and the towed cable resists lateral pressure and impact. In power and energy storage, the spun fibre, valve trigger fibre, and high-voltage flame-retardant cable safeguard safety across the entire chain. Leveraging its independent specialty fibre capabilities, YOFC will continue to push into extreme environments, extending fibre sensing to every frontier of human exploration.

Laser Smart Manufacturing Solutions:

Spanning the Full Chain to Power the Upgrade of Intelligent Manufacturing

Leveraging the industrial synergy between its subsidiaries Everfoton and Penta Laser, YOFC presented on site a complete laser smart manufacturing solution spanning specialty fibre for lasers, core laser light sources, and high-power laser intelligent equipment. The exhibits cover specialty fibre across all power levels, wavelengths, and pulse widths, high-quality optical fibre lasers for intelligent applications, and high-end laser cutting and welding equipment for high-power applications, with a focus on a series of laser products serving diverse scenarios such as 3D printing, new energy, consumer electronics, and sheet-metal processing—differentiated solutions that directly address the imperative of intelligent manufacturing.

All-Optical Intelligent Vehicle:

Reinventing In-Vehicle Communication Architecture for the 10-Gigabit Era

YOFC presented its "All-Optical Intelligent Vehicle" solution on site, achieving three breakthrough upgrades: 10-gigabit lossless bandwidth that keeps massive sensor data flowing in real time; all-scenario electromagnetic interference immunity that ensures reliable transmission of critical control signals; and lightweight wiring harnesses that effectively reduce vehicle weight and wiring complexity. The solution covers core scenarios such as in-vehicle fibre lighting, in-vehicle optical communication, and optical amplifiers for LiDAR, providing high-bandwidth, highly reliable, low-latency optical transmission for intelligent driving.

Space Communication Solutions:

Highly Reliable, Radiation-Resistant Fibre for the Vastness of Space

YOFC's space communication solutions cover three core scenarios. In astronomical observation, YOFC partnered with the National Astronomical Observatories, Chinese Academy of Sciences (NAOC) to develop specialty wide-spectrum fibres tailored to multi-object sky surveys and integral field unit (IFU) systems, precisely capturing the faint starlight of the universe. In high-precision space fibre sensing, radiation-resistant passive fibres cover single-mode, multimode, and polarization-maintaining types, standing up to deep-space radiation and extreme temperature swings. In environments of extreme radiation, the radiation-resistant cable has undergone full qualification testing for radiation, thermal cycling, and vacuum conditions, ensuring unyielding link integrity.
