Breaking away from traditional solid-core fibre transmission mediums, hollow core fibres feature an air-guiding waveguide structure. They are characterized by low latency, wide transmission bandwidth, low loss, and low nonlinearity, making them ideal for high-capacity, high-speed,low-latency, and long-distance optical transmission networks. These networks are particularly well-suited for various fields, such as computing power networks, AI data centers, dedicated lines for industrial finance, and electric power networks. Additionally, hollow core fibres exhibit ultra-low Rayleigh scattering, low dispersion, large effective area, tunable wavelength, and higher laser damage thresholds. These properties render them highly promising for applications in high-power laser transmission, ultraviolet to mid-infrared optical transmission, pulse compression, quantum transmission, and gas sensing.
As a world-leading supplier of communication fibre products, YOFC is committed to the research and development of hollow core fibre series. By leveraging independently synthesized raw materials, a capillary preparation process with precise size control, and a cutting-edge drawing process for hollow core fibres, YOFC has developed a range of hollow core fibres suitable for wavelengths spanning from visible light to mid-infrared. These fibres have achieved internationally leading performance levels and scale production. Furthermore, YOFC offers a comprehensive suite of solutions encompassing hollow core fibre cables and hollow core fibre adapters, ensuring rapid responses to diverse customer needs and facilitating batch delivery.
