Ceramic ferrules offer superior durability and performance over other ferrule materials while offering improved end-face geometry and polishing for low insertion loss and minimal back reflection. Precise control of extrusion pressure enables continuous concentric molding. These ferrules are available in both ceramic and stainless steel and are designed to meet the space requirements of specialty applications. 5 mm stainless steel or ceramic (zirconia) fiber optic ferrules for constructing pigtailed fiber optic patch cables and assemblies. Available ferrule types from SINO OPTIC are SC, FC, LC, ST, MU, SMA with flat, dome, cone, step, or pre-angled end-faces.
