## Summary description

DIGITUS DK-39121-U-0100 is a 100 m fibre optic cable designed for high-performance data links. It uses OS2 single-mode fibre with a 9 µm core and A/I-DQ(ZN) BH construction. The cable is suited for long-distance and backbone installations, InfiniBand and fibre applications, offering low attenuation and reliable signal transmission in networking and data centre environments.

## Long description

DIGITUS DK-39121-U-0100 is a 100 m single-mode fibre optic cable designed for backbone and long-distance data transmission. It features OS2 (9/125 µm) G.652.D optical fibres in a single central loose tube with non-metallic rodent protection and a LSZH outer sheath rated CPR Dca. The compact design combines tensile strength and flexibility for indoor and outdoor installations, with manufacturer quality control according to ISO9001, REACh and RoHS for consistent performance and reliability.
Advantages
The cable provides low attenuation across 1310, 1550 and 1625 nm wavelengths and low macro-bending loss, ensuring stable signal transmission. Its LSZH jacket minimizes smoke and halogen emission in case of fire, while UV resistance and longitudinal/transverse water resistance improve durability. The metal-free construction with glass yarn reinforcement and non-metallic rodent protection offers corrosion-free operation and reduced electrical risk.
Suitable for
Backbone and long-distance fibre links
Data centres and telecommunications distribution
Indoor and outdoor duct or tray installations
InfiniBand and high-speed single-mode applications

How to use
Route the DIGITUS DK-39121-U-0100 cable in ducts, trays or along intended pathways according to site planning and local regulations. Observe the specified minimum bending radii during installation (20 × outer diameter) and avoid exceeding the maximum permissible tensile force (1400 N). Use appropriate cable glands and strain-relief fittings when entering equipment or enclosures. For splicing and terminations, follow standard single-mode fibre preparation, cleaving and fusion-splicing procedures, then verify attenuation and continuity measurements after installation.
Usage recommendations
Store and transport the cable within the specified temperature limits, protect cable ends from contamination and verify optical loss after installation. For long-term outdoor exposure, ensure UV-protected routing and periodic inspection of the sheath; maintain records of insertion loss and PMD for critical links.
