Panduit FWUYL7575KAM065 24-Fiber OM5 QuickNet Trunk Cable Assembly
The Panduit FWUYL7575KAM065 is a factory-terminated 24-fiber OM5 wideband multimode trunk cable assembly engineered for high-density data center deployments requiring rapid installation and extended reach. This 65-meter (213.25-foot) QuickNet trunk delivers 30 to 40 percent space savings over conventional trunk assemblies through reduced-diameter construction, directly addressing pathway congestion and airflow restriction in dense overhead and underfloor routing scenarios. The OM5 fiber specification supports legacy 10G/40G applications while future-proofing infrastructure for 100G short-wavelength division multiplexing (SWDM) across all four OM5 wavelength windows. LSZH jacketing meets international low-smoke zero-halogen flammability standards for occupied spaces and mission-critical facilities.

Panduit's QuickNet factory-terminated trunk cable assemblies solve the field termination bottleneck that traditionally delays data center turn-ups and introduces variability in optical performance. Each FWUYL7575KAM065 trunk ships with all 24 fibers pre-polished and insertion-loss tested at the factory, guaranteeing consistent sub-0.3 dB connector performance across the entire assembly. This eliminates the need for fusion splicing trucks, field test equipment, and specialized fiber technicians during installation—critical advantages when deploying multi-rack infrastructure under compressed schedules or in operational data centers where hot-work permits and technician access windows are tightly constrained. The 65-meter length is specifically dimensioned for cross-aisle connections in standard raised-floor data centers (typically 50-60 meters of horizontal run plus vertical drops and service loops), reducing the number of interconnect points and associated insertion loss penalties compared to shorter pre-terminated assemblies daisy-chained together.
The OM5 wideband multimode fiber specification represents a significant evolution beyond OM3 and OM4 for organizations planning 40G and 100G migrations. While OM3/OM4 fibers optimize performance around the 850 nm wavelength used by traditional VCSEL transceivers, OM5 adds three additional wavelength windows (880 nm, 910 nm, and 940 nm) to support short-wavelength division multiplexing. This enables 100GBASE-SR4 transmission using four wavelengths over a single duplex fiber pair—quadrupling effective bandwidth without requiring parallel fiber infrastructure or costly singlemode conversions. For facilities currently running 10GBASE-SR or 40GBASE-SR4, OM5 provides backward compatibility with existing transceivers while eliminating the need for future re-cabling when 100G links are required. The 50-micron core diameter maintains compatibility with standard LC, SC, and MPO connector systems, allowing seamless integration with existing patch panels, cassettes, and cross-connect hardware.
The reduced-diameter trunk construction addresses one of the most persistent challenges in high-density data center design: pathway fill and airflow obstruction. Traditional 24-fiber trunk cables often exceed 12-15 mm outer diameter when built to older cable designs, consuming disproportionate cable tray real estate and creating airflow dams in overhead hot-aisle returns. Panduit's small-diameter trunk reduces outer diameter by approximately 35 percent through optimized buffer tube geometry and tight-buffered fiber management, allowing significantly higher cable counts within the same 4-inch ladder rack or cable basket. This space reclamation is particularly critical in retrofit scenarios where adding new fiber trunk capacity to fully loaded existing pathways would otherwise require costly tray expansions or secondary routing. The smaller bend radius also simplifies routing around tight corners, through vertical cable managers, and into congested rear-of-rack zones where space behind patch panels is at a premium.
LSZH jacketing is increasingly mandated in data centers located within occupied buildings, below-grade vaults, and international facilities where halogenated flame retardants are prohibited by local code. When exposed to fire, PVC-jacketed cables release hydrochloric acid gas that corrodes electronic equipment, obscures visibility, and poses acute inhalation hazards; LSZH compounds produce significantly lower smoke density and zero corrosive halogens, improving both life-safety egress conditions and equipment survivability during fire events. The IEC 60332-3C flame test rating (equivalent to UL 1685 and NFPA 262) certifies that the cable will not propagate flame along a vertical cable tray under the standardized test conditions—essential for installation in vertical shafts, riser pathways, and return-air plenums where fire codes require plenum-rated or LSZH-rated cables. For projects requiring LEED certification or other green-building standards, LSZH cables also eliminate the halogenated compounds that contribute to environmental persistence and bioaccumulation concerns.
The lime green jacket color is Panduit's standard for OM5 fiber identification and aligns with TIA-598-D color coding recommendations for wideband multimode fiber. In data centers managing parallel networks (production, storage, management, out-of-band), color-coding trunk cables by fiber type dramatically reduces the risk of cross-connecting incompatible media or misidentifying cable paths during maintenance. Lime green provides high visual contrast against the aqua (OM3), erika violet (OM4), yellow (singlemode OS2), and black (copper) cables commonly found in the same pathways, enabling technicians to trace routes and verify connections without relying solely on label printing or asset databases. This is particularly valuable during after-hours maintenance windows when documentation may be incomplete or when troubleshooting urgent outages where rapid visual confirmation of the correct fiber path is critical.
The 24-fiber count is the most common trunk density for spine-leaf data center fabrics and storage-area network consolidation. A single FWUYL7575KAM065 trunk supports twelve duplex connections (twelve transmit/receive pairs), sufficient to uplink a full 10-port leaf switch with two redundant connections remaining for management or out-of-band access. For MTP/MPO-based structured cabling systems, 24 fibers align perfectly with standard MTP-24 cassette modules, eliminating the fiber-count mismatches and unused dark fibers that occur when deploying 12-fiber or 36-fiber trunks in 24-port cassette environments. Organizations migrating from 1G/10G copper to 10G/25G fiber can use a single 24-fiber trunk to replace an entire 24-port copper switch uplink bundle, reclaiming significant rack space and reducing power consumption by eliminating copper transceivers and active top-of-rack aggregation.
Installation of the FWUYL7575KAM065 follows standard trunk cable best practices: maintain minimum bend radius of ten times cable outer diameter during pulls (approximately 120 mm for this assembly), secure cables every 1.5 meters along horizontal runs to prevent sag and excessive weight loading on connectors, and provide service loops of 1-3 meters at each termination point to accommodate future re-routing or equipment moves. The factory-installed connectors are protected by dust caps during shipping and should remain capped until final connection to patch panels or equipment to prevent endface contamination. Even in controlled data center environments, airborne particulates can degrade connector insertion loss by 0.5 dB or more if endfaces are left exposed; cleaning contaminated connectors in-situ after installation is significantly more labor-intensive than simply maintaining dust caps until connection. For installations requiring plenum rating verification, confirm that local AHJs accept LSZH as plenum-equivalent—most US jurisdictions recognize IEC 60332-3C as meeting NFPA 90A requirements, but some localities still mandate UL 910 (OFNP) testing; consult your electrical inspector before finalizing cable specification.
