INFRALAN U-DQ(ZN)BH OM3 24G single-fiber 1x24 LSZH black 5.8mm optical fiber cable

The INFRALAN U-DQ(ZN)BH OM3 24G single-fiber 1x24 LSZH black 5.8mm optical fiber cable is a multimode indoor/outdoor cable designed for installations that require OM3 performance. Supplied as a single 1x24 fiber unit, it combines a stranded zinc-coated central strength member with a low-smoke, halogen-free (LSZH) black outer sheath and a compact 5.8 mm diameter. The cable is intended for structured cabling in data centers, horizontal runs and backbone links where multimode OM3 characteristics and a small footprint are needed.

Advantages

This cable offers OM3 multimode performance suited to high-speed short-reach links while maintaining a compact 5.8 mm diameter for space-efficient routing. The zinc-coated stranded central strength member provides tensile strength for installation and limited outdoor exposure, and the LSZH jacket reduces smoke and halogen emission in confined spaces. The single 1x24 construction simplifies deployment where a concentrated multi-fiber route is required.

Suitable for

• Data center interconnects and short-reach multimode links
• Horizontal cabling inside commercial buildings
• Backbone fiber runs in mixed indoor/outdoor pathways with limited environmental exposure
• Racks and cabinet routing where small diameter cables reduce congestion

When it may not be suitable

This cable is multimode OM3 and therefore not appropriate for single-mode long-haul links or applications that require single-mode performance. It is designed for indoor/outdoor rated paths with limited exposure; it is not intended for continuous direct burial without additional protective conduits or for installations requiring full outdoor UV-resistant jackets.

Key specifications

• Fiber type: Multimode OM3
• Fiber count/configuration: 1x24 single-fiber bundle (24 fibers)
• Sheath material: Low-smoke, zero-halogen (LSZH)
• Outer diameter: 5.8 mm
• Strength member: Stranded zinc-coated central strength member
• Colour: Black outer jacket
• Application rating: Indoor/outdoor rated for limited external exposure

How to use

Route the cable following standard fiber handling practices: avoid tight bends, maintain the manufacturer’s minimum bend radius, and secure the cable to prevent mechanical strain on connectors. When terminating, use appropriate multimode OM3 compatible connectors and polishing/cleaving techniques, and perform standard loss and continuity tests after installation. For runs that transition from outdoor to indoor environments, protect the cable at entry points with grommets or transition enclosures.

What to consider before purchase

• Confirm that OM3 multimode performance meets your link budget and distance requirements
• Verify the 24-fiber count and 1x24 configuration fit your rack, patch panel and connector needs
• Assess environmental exposure to determine if additional conduit or protective jacketing is required
• Ensure compatibility with planned multimode connectors and transceivers

Usage recommendations

For optimal performance, use this OM3 multimode cable for short-reach, high-bandwidth links in data centers and building backbones. Adhere to minimum bend radius guidelines, protect transitions between outdoor and indoor sections, and perform optical loss testing after termination to verify compliance with system requirements.
