Idealphotonics' offers stainless steel and ceramic ferrules. Stainless steel ferrules, made from high-hardness metals (such as 316L), provide mechanical strength and corrosion resistance, making them suitable for harsh industrial environments. Ceramic ferrules (such as ZrO₂), with their ultra-low coefficient of thermal expansion (≈7×10⁻⁶/℃) and submicron-level concentricity (<0.5μm), ensure durable and precise fiber alignment, guaranteeing low-loss optical signal transmission.Key parameters for the ceramic ferrule include mechanical strength (tensile strength > 500N), corrosion resistance (salt spray test > 1000h), and tolerance accuracy (±1μm). The key parameters for the ceramic ferrule are concentricity (<0.5μm), thermal stability (coefficient of thermal expansion ≈7×10⁻⁶/℃), hardness (HV > 1200), and surface roughness (Ra < 20nm). Together, these ensure the physical durability and optical alignment accuracy of the fiber optic connection.
