DIGITUS DK-35041/3-U Indoor and Outdoor Installation Fiber Optic Cable 4 Fibers OM3 50/125 µm LSZH CPR Dca

The DIGITUS DK-35041/3-U Indoor and Outdoor Installation Fiber Optic Cable is a reliable network communication solution designed for diverse environments. Featuring 4 fibers with an OM3 50/125 µm core type and an LSZH jacket with a CPR Dca rating, this cable supports high-speed data transmission for structured cabling systems. It combines flexibility with high tensile strength in a compact design, ensuring excellent optical transmission and physical performance for professional networking needs.

Advantages

This fiber optic cable offers robust protection through its glass yarn armouring and non-metal rodent protection, making it suitable for both indoor and outdoor installations. It is longitudinally and laterally water-resistant as well as UV-resistant, ensuring long-term durability in challenging weather conditions and field environments. The low smoke zero halogen outer sheath enhances safety by reducing toxic emissions in case of fire, while the metal-free construction simplifies handling during installation.

Suitable for

• Indoor and outdoor structured cabling systems
• High-speed data transmission networks
• Campus network backbones connecting multiple buildings
• Industrial and commercial telecommunication installations

When it may not be suitable

This cable may not be appropriate for applications requiring a high fiber count exceeding 4 fibers, as it is specifically designed with a central loose tube containing 4 fibers. Additionally, it is not intended for heavy-duty direct burial without supplementary conduit protection.

How to use

Plan the cable route carefully, ensuring that bending radii and pulling forces remain within the specified technical limits during installation. The cable can be pulled through conduits, cable trays, or laid directly in managed pathways for indoor and outdoor sections. Ensure proper termination using compatible OM3 fiber optic connectors and splice equipment by trained personnel to maintain optimal signal integrity and low attenuation.

What to consider before purchase

• Verify the required fiber count and core type for your network infrastructure
• Check local fire safety regulations to ensure CPR Dca and LSZH ratings meet building requirements
• Assess environmental conditions to determine if UV and water resistance are sufficient for the installation path

Ensure that installation is performed by qualified technicians following standard telecommunication practices, and always respect the maximum pulling force and minimum bending radius parameters to prevent performance degradation.
