Singlemode fibers G.652.D

The wide-area standard – millions of installations worldwide

This fiber is the standard for transmissions across the entire wavelength range from 1,260 nm to 1,625 nm. Thanks to its reliably low long-term attenuation at 1,383 nm (Low Water Peak), the fiber not only supports applications at the conventional 1,310 nm and 1,550 nm wavelengths, but also in the broadband range (CWDM, DWDM). This fiber is the ideal choice when cost optimization needs to be matched to maximum flexibility in fiber-optic networks.

  • Lowest attenuation for long lengths
  • Optionally available in 16 colors plus flexible ring marking
  • Optionally available with alternative coatings for an extended temperature range – high-temperature fibers
  • Made in Germany

Your advantages at a glance

  • Fully standardized – compatible with use for 1,310 nm, 1,550 nm, and 1,625 nm
  • Lowest attenuation across the entire range (Low Water Peak), enables a wide choice of wavelength-selective transmission channels (CWDM/DWDM)
  • Lowest splice attenuation thanks to controlled production/testing procedures
