The 2.5mm OD Ceramic Ferrule with Flange for SC/FC/ST Fiber Connector is a high-precision zirconia ferrule designed to ensure accurate fiber alignment and superior optical performance. Manufactured from high-purity zirconia ceramic, it offers excellent hardness, thermal stability, and wear resistance, resulting in consistent low insertion loss and high return loss. The flanged design provides easy handling and precise positioning during connector assembly, making it ideal for SC, FC, and ST type connectors in both singlemode and multimode applications. It is widely used in optical communication systems, fiber optic patch cords, adapters, and transceivers where precision and reliability are essential.
