Import Tips
• Verify fiber specifications match 'optical fiber' definition excluding cable assemblies; provide attenuation and numerical aperture test data,Include manufacturer specs confirming singlemode characteristics and wavelength range for customs classification,Avoid common pitfall of importing pre-connectorized cables which shift to 8544; import bare spools only
