ST ceramic ferrule is generally treated as the core part of the ST connectors. The ST ferrule uses 2.5mm diameter fiber optic ceramic ferrules with PC end-face. The ST zirconia ferrule hole size 125um, 125.5um, 126um and hole concentricity of typically 1um are for single mode performance; the ferrule hole size 126um, 126.5um, 127um and hole concentricity of typically 4um are for multimode performance.
