Protector Phosphor Bronze Sleeve for Fiber Optic Standard SC/FC/ST connectors. Phosphor bronze sleeves achieve moderate precision through stamping and turning processes, with metallic properties that allow for minor dimensional adjustments to accommodate tolerance variations, ensuring broad compatibility at a competitive cost.
Fiber optic communication systems often operate in harsh environments (e.g., outdoor FTTX cabinets, industrial sites with high humidity or dust). While ceramic materials are corrosion-resistant, their porous microstructures can absorb moisture or contaminants over time, affecting long-term stability.

The ferrule is the most important component of fiber connectors and fiber patch cords. While ferrules can be made from plastics, stainless steel, or ceramic (zirconia), most optical connectors use ceramic (Zirconia) material due to its desirable properties including low insertion loss, remarkable strength, small elasticity coefficient, easy control of product characteristics, and strong resistance to environmental changes.
The outer diameter (OD) Ceramic (Zirconia) Ferrule size for ST, FC and SC Fiber Connectors is φ2.5mm, while for MU and LC Fiber Connector Versions it is φ1.25 mm. The OD Ceramic (Zirconia) Ferrules size is precise with a tolerance level of ±0.0005 mm. The inner diameter (ID) Ceramic Ferrules size has a precision of 0.001mm in concentricity and 0.0005mm in eccentricity for single mode ferrules used for optical communication components.
For multimode ferrules used in LAN and/or SAN Applications, the OD Ceramic Ferrules size is precise with a tolerance level of ±0.001 mm, while the inner diameter (ID) has a precision of 0.003mm in concentricity and 0.004mm in eccentricity.
