Singlemode fibers G.657.A2 (250µm u. 200µm)

The fiber for connection technology involving extreme requirements for bending properties

  • The fiber of choice for demanding service connection cabling applications (FTTB, FTTD, FTTO)
  • Designed to minimize attenuation growth due to bending (macrobending)
  • Optionally available in 16 colors plus flexible ring marking
  • Available as a mini version with 200 µm coating for increased fiber count in cable
  • Optionally available with alternative coatings for an extended temperature range – high-temperature fibers
  • Made in Germany

Your advantages at a glance

  • Can be used anywhere applications require many tight bends (structured cabling to workplace, electrical enclosure, etc.)
  • Reduced sensitivity to macrobending: increase in attenuation cut by 10x
    (at 1,625 nm) compared with standard singlemode fibers
  • Standards-compatible for use with 1,310 nm, 1,550 nm, and 1,625 nm
  • Lower attenuation across the entire range (Low Water Peak), enables a wide choice of wavelength-selective transmission channels (CWDM/DWDM, OS2 level)
  • Optimized coating system ensures very good microbending behavior, making it a proven solution for all cable designs, e.g. loose tubes, central loose tubes, slotted core cable, patch cords, j-fiber Units
  • Mini-version (200 µm) allows significantly higher fiber counts for a specified core diameter
