Ceramic Ferrules
Upcera specializes in high-precision ceramic ferrules including SC-type, LC-type, and custom large-bore designs, engineered to meet the demanding needs of 5G, data centers, and fiber laser systems.
1. 20+ years of ceramic manufacturing experience
2. Factory-direct supply with guaranteed quality
3. 100% concentricity inspection
4. High precision and reliable performance
5. Custom production available
Ceramic ferrules are critical components in fiber optic connectors and adapters. With exceptional dimensional precision and stable optical performance, they are widely used in optical communication networks, data centers, FTTx deployments, 5G infrastructure, and high-end testing equipment.
We offer a wide variety of ceramic ferrule types made primarily from high-purity zirconia. These ferrules feature excellent wear resistance, tight concentricity, and a thermal expansion coefficient well-matched to optical fibers. Custom designs with non-standard dimensions or structures are also available to meet specific application needs.
With years of expertise in ceramic ferrule manufacturing, UPCERA provides high-volume, stable production capabilities. Our products can achieve micron-level tolerances and support value-added processing such as end-face polishing and laser marking — ensuring high performance, precision, and cost-effectiveness for our customers.
