INFRALAN fiber optic cable U-DQ(ZN)BH OM1 4G (1x4) Eca 2000N LSZH black 5.8mm

INFRALAN fiber optic cable U-DQ(ZN)BH OM1 4G (1x4) Eca 2000N LSZH black 5.8mm is a multimode indoor/outdoor cable designed for structured cabling where fire safety and mechanical resilience are required. The cable incorporates four OM1 multimode fibers arranged in a 1x4 configuration within a compact 5.8 mm low-smoke, halogen-free jacket. It provides a balance of optical performance and physical protection for backbone, horizontal and campus links.

Advantages

The LSZH sheath reduces smoke and hazardous gas emissions in case of fire while the Eca-rated construction meets basic reaction-to-fire classification for many building installations. With 2000 N tensile strength and a durable outer jacket, the cable resists pulling forces and mechanical stress during installation and operation. The OM1 multimode core supports legacy multimode systems and short-reach multimode links in data centers and enterprise networks.

Suitable for (tasks / use cases)

• Indoor backbone and horizontal cabling in commercial and institutional buildings
• Campus interconnects and short outdoor runs where limited environmental exposure is present
• Data center short-reach multimode connections and patching
• Environments requiring low-smoke, halogen-free materials for improved fire safety

When it may not be suitable

This multimode OM1 cable is not intended for long-haul single-mode applications or for connections that require high-bandwidth multimode standards (such as OM3/OM4 for 10G+ over longer distances). It is also not designed for continuous direct burial or harsh outdoor exposure without additional armoring or conduit protection.

Key specifications

• Fiber type: Multimode OM1
• Fiber count and configuration: 4 fibers in 1x4 arrangement
• Outer diameter: 5.8 mm
• Sheath material: Low-smoke, zero-halogen (LSZH)
• Fire classification: Eca (reaction to fire)
• Tensile strength: 2000 N
• Color: Black
• Application: Indoor/outdoor (limited outdoor exposure)

How to use

Plan the route and secure adequate protection for any sections exposed to mechanical damage or weather. Use appropriate fiber cable preparation tools to strip the LSZH jacket and buffer tubes, and follow standard fiber termination procedures for connectors or splices compatible with OM1 multimode fibers. Observe recommended minimum bend radius during routing and after installation to avoid increasing attenuation. Test links with suitable multimode test equipment to verify insertion loss and continuity before commissioning.

What to consider before purchase

• Required transmission distances and whether OM1 multimode meets your bandwidth needs
• Installation environment — whether conduit or additional armoring is needed for outdoor sections
• Compatibility with existing connectors and equipment optimized for multimode fibers
• Fire safety and building code requirements for LSZH and Eca-rated cables in your facility

Usage recommendations

Maintain manufacturer-recommended bend radii, avoid exceeding the 2000 N tensile limit during pulling, and protect exposed cable runs from UV and moisture. For higher-speed or longer multimode links consider evaluating OM3/OM4 alternatives; for outdoor or direct-burial runs, add appropriate armoring or conduit.
