Key inspection parts of optical cables
Fiber coating: Heavy metal content in UV-cured acrylate
Core filling: Chemical compliance of thixotropic gel
Sheath material:
PVC: Lead/cadmium stabilizers need to be tested
LSZH: Focus on brominated flame retardants
Strengthening components:
Metal armor layer: Hexavalent chromium passivation treatment
FRP non-metallic reinforcement: Resin system compliance
Connector components (if applicable):
Solder: Lead-free requirements (Sn-Ag-Cu alloy)
Plating: Heavy metal migration risk of nickel/gold plating
