Singlemode Fibers G.657.A1

The bend-optimized alternative for demanding applications

Significantly reduced increase in attenuation due to bending compared with G.652.D fibers (macrobending)

Available as a mini version with 200 µm coating for increased fiber count in cable

Optionally available in 16 colors plus flexible ring marking

Optionally available with alternative coatings for an extended temperature range – high-temperature fibers

Made in China

Your advantages at a glance

Fully standardized – compatible with use for 1,310 nm, 1,550 nm, and 1,625 nm

Reduced sensitivity to macrobending: increase in attenuation cut by 5x to 10x (at 1,550 nm) compared with standard singlemode fibers

Lower attenuation across the entire range (Low Water Peak), enables a wide choice of wavelength-selective transmission channels (CWDM/DWDM, OS2 level)

Lowest splice attenuation thanks to controlled production/testing procedures

Very good microbending behavior makes it a proven solution for all cable designs, e.g. loose tubes, central loose tubes, slotted core cable, patch cords, j-fiber Units

Ideal for use in metro networks, LAN, and structured cabling

Mini-version (200 µm) allows significantly higher fiber counts for a specified core diameter
