DWDM Single-Mode Optical Fiber G.655 from China

Non-zero dispersion shifted single-mode fiber (G.655) optimized for Dense Wavelength Division Multiplexing (DWDM) systems carrying high-capacity voice, data, and video over submarine and terrestrial long-haul networks. It supports multiple wavelengths with minimized non-linear effects. Falls under HTS 9001.10.0030 for communication transmission fibers.

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
