Import Tips
• Provide chromatic dispersion curves and PMD specifications to confirm DWDM communication use
• Declare coating type (e.g
• dual-layer acrylate) but ensure no complete cable assembly to maintain 9001 classification
• Check for zero-water peak fiber variants which may require additional spectral attenuation data
