alumina ceramic sleeve Fiber Optic Standard SC Fiber Optic Copper Sleeve fiber optic Sleeve
Phosphor bronze sleeves provide moderate precision through stamping and turning processes, with metallic properties that allow minor dimensional adjustments to accommodate tolerance variations. This ensures broad compatibility at a lower cost compared to ceramic alternatives.
In fiber optic copper sleeve protector design and selection, ceramic sleeves are not preferred, while metal sleeves such as phosphor bronze are often used due to fundamental differences in material properties, functional positioning, and application scenario requirements.

- High precision and reliability
- Excellent strength, durability and anti-aging performance
- Various types of ferrules and end-faces
Ferrule is the most important component of fiber connectors and fiber patch cords. Made from zirconia ceramic material, these ferrules offer low insertion loss, remarkable strength, small elasticity coefficient, easy control of product characteristics, and strong resistance to environmental changes.
Outer diameter ceramic ferrule sizes are φ2.5mm for ST, FC and SC fiber connectors, and φ1.25mm for MU and LC fiber connector versions, with precision tolerance levels of ±0.0005mm for single mode and ±0.001mm for multimode applications.
