Huawei optical fiber preform and optical cable

Huawei optical cables are manufactured from high-purity preforms and include hybrid and transparent indoor fiber solutions designed for flexible, high-performance deployment.

Optical Fiber Preform and Manufacturing

Optical fibers begin as preforms, which are cylindrical rods of ultra-pure silica glass doped with materials like germanium tetrachloride to increase the refractive index of the core and fluorine compounds to lower the cladding index, ensuring efficient light confinement. The preform is then drawn into thin fibers under controlled heating, producing fibers with precise diameters, low attenuation, and high mechanical strength. Impurities such as water or metals can significantly increase signal loss, so high-purity materials are critical for long-distance and high-speed transmission.

Hybrid Copper-

Fiber Cables: Huawei's hybrid cables integrate optical fibers and copper conductors to support both data and power transmission, such as PoE++ for Wi-Fi 6/7 APs. The second-generation hybrid cables (V2. 0) integrate fibers and copper at termination points, simplifying deployment and reducing cabling workload.

These cables are lightweight, flexible, and can be cut and terminated on-site without extensive surveys. 2. Transparent Indoor Optical Cables: Huawei also offers pre-connected transparent bow-type cables with hot-melt adhesive for indoor deployment.

These cables can be rapidly installed on walls, ceilings, or baseboards using a fiber installation kit (FIK). Proper installation requires maintaining a minimum bending radius, using corner protectors, and reinforcing with clips or adhesive to ensure reliability. They are designed for aesthetic indoor environments and must avoid high-temperature exposure or uneven surfaces.

Installation and Safety Considerations

Always use Huawei-certified optical modules to ensure transmission reliability. Maintain a minimum bend radius (≥40 mm for standard fibers) to prevent signal degradation. Avoid over-tight bundling of fibers, which can reduce performance.

For transparent indoor cables, ensure surfaces are suitable for hot-melt adhesive and avoid direct sunlight or high temperatures above 60–70°C. Use protective equipment to prevent eye damage from laser light during installation.

Summary

Huawei optical fiber solutions combine high-quality preform-based fibers with innovative cable designs for hybrid and indoor applications. The preform ensures low-loss, high-strength fibers, while hybrid and transparent cables provide flexible deployment options for enterprise networks, Wi-Fi access points, and indoor cabling scenarios. Proper installation and adherence to safety guidelines are essential for maintaining performance and reliability.
