INFRALAN U-DQ(ZN)BH OM3 24G single 24-fiber LSZH black 7.5mm optical cable

INFRALAN U-DQ(ZN)BH OM3 24G single 24-fiber LSZH black 7.5mm optical cable is a multimode fiber cable intended for high-speed data transmission over OM3 links. The cable combines a 24-fiber single core with a low-smoke, halogen-free jacket and a compact 7.5 mm outer diameter, making it suitable for structured cabling in data centers, enterprise networks and backbone segments where space efficiency and fire-safety requirements are important.

Advantages

The cable offers multimode OM3 performance optimized for 10 Gbit/s and 40/100 Gbit/s short-reach applications, while the LSZH sheath reduces smoke and toxic emissions in the event of fire. Its single 24-fiber construction simplifies fiber management and installation compared with multiple smaller cables, and the 7.5 mm diameter provides a balance between mechanical robustness and space-saving routing in trays and conduits.

Suitable for

• Data center horizontal and backbone links
• Enterprise LAN backbone and riser installations
• Fiber trunking between patch panels and distribution frames
• Short-reach high-bandwidth multimode connections (10G/40G/100G within OM3 limits)

When it may not be suitable

The cable is multimode OM3 and is not intended for long-distance single-mode links; for long-haul or single-mode networks a single-mode fiber cable is required. Applications requiring a highly flexible or microcable with smaller bend radius or extremely tight spaces may prefer slimmer cable designs or breakout cables.

Key specifications

• Fiber type: multimode OM3
• Number of fibers: 24 (single 24-fiber core)
• Outer diameter: 7.5 mm
• Sheath material: LSZH (low smoke, zero halogen)
• Fire performance class: Eca (cable reaction to fire class)
• Tensile performance: designed for typical installation tension up to 3000 N
• Color: black

How to use

Plan the route through cable trays, conduits or rack channels, respecting the recommended minimum bend radius for multimode fiber to maintain optical performance. Terminate or patch the cable at fiber distribution panels or patch panels using appropriate 24-fiber MPO/MTP or fanout assemblies depending on the chosen connectivity. During installation avoid exceeding the specified tensile load and protect cable ends from contamination; use proper cleaning procedures and test light loss after termination to verify link performance.

What to consider before purchase

• Confirm OM3 multimode is appropriate for your link distances and transceiver types.
• Verify connector/termination style required (MPO/MTP trunk, or need for breakout assemblies).
• Ensure route space and bend radius compatibility with the 7.5 mm diameter cable.
• Check fire safety class and LSZH requirement for your building or data center regulations.

Usage recommendations

Use this INFRALAN OM3 24-fiber LSZH cable for structured backbone installations where multimode high-speed links are required; pair with certified OM3 transceivers and perform optical loss testing after installation to ensure compliance with link budgets.
