By focusing on these core strengths, we’ve grown into a globally recognized ceramic component supplier whose products are used in 5G networks, fiber lasers, and state-of-the-art data centers.

Precision Ceramic Sleeves and Ferrules

At UPCERA, we take pride in being a trusted ceramic component supplier, offering high-performance ceramic sleeves and ferrules that are essential to the fiber optic communication industry. These core products play a critical role in enabling fast, stable, and high-volume data transmission across modern networks.

Advanced Ceramic Sleeves

Our SC/LC ceramic sleeves are manufactured using advanced processing techniques that ensure unmatched precision and reliability. Designed for optical fiber connectors, these sleeves support accurate fiber alignment, reducing signal loss and enhancing connection stability.

• Key benefits include:

✅ Ultra-tight tolerances (±0.5 µm) to guarantee minimal insertion and return loss

✅ High wear resistance, supporting thousands of connection cycles without degradation

✅ Excellent thermal stability, allowing consistent performance in varying environments

Every sleeve is rigorously tested to meet international standards, ensuring durability even in mission-critical applications like data centers and 5G base stations.

Tailored Ceramic Ferrules

Ferrules are the centerpiece of fiber optic connectors, aligning and protecting the delicate fibers. We offer a comprehensive range of ferrules designed to meet diverse application needs:

✅ Standard SC and LC ferrules, widely used in telecommunications and networking infrastructure

✅ Large-bore ferrules, ideal for fiber laser systems and specialty connectors

✅ Custom ferrules, crafted with complex geometries and materials for unique project specifications

As a forward-thinking ceramic component supplier, we utilize more than precision CNC machining and proprietary sintering processes to ensure every ferrule achieves high dimensional accuracy, minimal concentricity error, and optimal polishing quality.
