INFRALAN U-DQ(ZN)BH OM4 24G 1x24 LSZH black fiber optic cable, 2000 N tensile, 5.8 mm

INFRALAN U-DQ(ZN)BH OM4 24G 1x24 LSZH black fiber optic cable is a multimode trunk cable designed for high-density installations and high-speed data transmission. The OM4 fibers support increased bandwidth for modern data center and campus backbone applications. The cable features a low-smoke zero-halogen (LSZH) outer jacket in black, a compact 5.8 mm outer diameter and a rated tensile strength of 2000 N, making it suitable for routed trunking and structured cabling where limited space and safety standards are required.

Advantages

This multimode OM4 cable delivers improved modal bandwidth and lower attenuation compared with lower-grade multimode fibers, enabling longer reach or higher data rates for Ethernet, Fibre Channel and other multimode applications. The LSZH jacket reduces harmful smoke and halogen emissions in case of fire, supporting safety requirements in public and enclosed spaces. Its 5.8 mm diameter and 2000 N tensile rating provide a balance of flexibility and mechanical robustness for installation and routing in trays, conduits and racks.

Suitable for

• Data center trunking and patching where OM4 performance is required
• Campus backbone links between buildings and main distribution frames
• High-density fiber installations and pre-terminated harnesses
• Indoor installations with safety requirements for low smoke and halogen

When it may not be suitable

This cable is multimode OM4; it is not appropriate where single-mode fiber is required for very long-distance backbone runs or where single-mode compatible transceivers are specified. The LSZH jacket is optimized for indoor and riser applications but may not be suitable for direct burial or prolonged outdoor exposure without additional protection.

Key specifications

• Fiber type: Multimode OM4
• Configuration: 1x24 fibers (24 cores)
• Outer diameter: approximately 5.8 mm
• Jacket: Low Smoke Zero Halogen (LSZH), black
• Tensile strength: rated to 2000 N

How to use

Route the cable through cable trays, conduits or racks following site-specific bend-radius and installation guidelines. Terminate or connect the individual fibers to appropriate MPO/MTP or individual multimode connectors according to the planned patching scheme. During pulling, respect the 2000 N tensile limit and avoid sharp bends; secure the cable using appropriate clamps or ties compatible with LSZH jackets. Test insertion loss and continuity after termination to verify performance compliance with OM4 specifications.

What to consider before purchase

• Verify that OM4 multimode fiber meets the performance and compatibility requirements of your transceivers and network equipment
• Confirm that 24-fiber breakout and connector types (MPO/MTP or LC) match your patching architecture
• Ensure indoor LSZH jacket is appropriate for the installation environment (not for prolonged outdoor burial)
• Account for required spare length, bend radius, and routing methods to avoid exceeding tensile limits

Usage recommendations

For best results, plan connectorization and testing before deployment: use certified testers to measure insertion loss and return loss, maintain proper bend radius throughout routing, and use strain-relief and labeling in high-density panels to simplify maintenance and upgrades.
