DIGITUS Installation Cable Indoor/Outdoor OS2 9/125µ 4 Fibers CPR Dca LSZH DK-39041-U

The DIGITUS Installation Cable Indoor/Outdoor OS2 9/125µ 4 Fibers CPR Dca LSZH DK-39041-U is a high-performance fiber optic cable designed for reliable network installations across both indoor and outdoor environments. Featuring an OS2 9/125µ single-mode fiber type with 4 fibers, this cable ensures high-speed data transmission and excellent optical performance. It is constructed with a central loose tube design, providing high tensile strength and flexibility while maintaining a compact size. The durable outer jacket is made of Low Smoke Zero Halogen (LSZH) material, compliant with CPR Dca ratings, making it a safe choice for modern building installations.

Advantages

This installation cable offers exceptional durability and environmental resistance thanks to its UV-resistant and longitudinally and laterally water-resistant construction. It incorporates glass yarn armouring and non-metal rodent protection, ensuring safety against physical damage and pests without introducing metal elements. The loose tube design delivers high tensile strength and flexibility for demanding routing requirements. Furthermore, the LSZH jacket ensures low smoke emission in the event of fire, meeting strict building safety standards.

Suitable for

• Connecting buildings in campus network infrastructures
• High-speed indoor and outdoor telecommunication data links
• Enterprise LAN setups requiring damp-proof and rodent-resistant cabling
• FTTX installations and long-distance data transmission

This cable may not be suitable for applications requiring multi-mode fiber infrastructure or environments that demand extreme metallic armoring for heavy-duty industrial impact protection.

Key specifications

• Fiber optic type: OS2 single-mode 9/125µ
• Fiber count: 4 fibers
• Cable type: U-DQ(ZN) BH loose tube
• Jacket material: Low Smoke Zero Halogen (LSZH)
• Fire rating: CPR Dca
• Protection features: Water-resistant, UV-resistant, non-metal rodent protection, glass yarn armored
• Outer diameter: 6.5 mm
• Max allowable pulling force: 1400 N
• Crush resistance: 1000/200 N/100mm
• Operating temperature range: -40°C to +70°C

Proper installation requires careful handling to respect the minimum bending radius limits, which are 20 times the outer diameter during installation and 10 times during operation. Ensure that the maximum allowable pulling force of 1400 N is not exceeded when pulling the cable through conduits or trays. Professional tools for fiber stripping, cleaving, and fusion splicing should be used to terminate the 4 fibers safely and efficiently.

What to consider before purchase

• Verify that your network hardware requires single-mode OS2 fibers
• Measure the exact distance and routing path to account for indoor and outdoor transition points
• Check local building regulations regarding CPR Dca and LSZH jacket requirements
• Ensure appropriate termination equipment and splice trays are available

Usage recommendations: Plan your cable routing carefully to avoid sharp bends exceeding the minimum bending radius specifications. For outdoor entries, ensure proper sealing methods are applied to maintain water resistance over the lifespan of the network.
