Import Tips
• Reference ITU-T G.652 fiber compatibility in specs; multimode ferrules (G.651) have different tolerances
• Maintain humidity-controlled packaging during shipping to prevent zirconia phase transformation
• Country of origin marking mandatory; declare firing location as many Asian origins specialize in these
