Common Quality Checkpoints

Quality expectations should be matched to the product and order requirement. Buyers can ask for relevant checks rather than generic claims.

  • Connector end-face inspection and cleanliness confirmation where required.
  • Insertion loss and return loss checking for patch cords and cable assemblies.
  • Connector type, polish type, cable length, color, label and packing verification.
  • Visual confirmation for mixed BOM, kit packing and OEM/ODM label requirements.

What to Ask Before Shipment

For project orders, ask the supplier to confirm product photos, label information, quantity, carton marks and basic inspection records according to the actual product type.
