Panduit FWUYL7575KAM032 OM5 24-Fiber QuickNet Trunk Cable Assembly
The Panduit FWUYL7575KAM032 is a 24-fiber OM5 trunk cable assembly engineered for high-density data center backbones requiring extended reach and future-proof bandwidth. This 32-meter (105 ft) trunk features PanMPO female connectors on both ends with Method A polarity, HD Flex small-diameter construction that reduces pathway fill by 30-40%, and Low Smoke Zero Halogen (LSZH) jacketing for plenum and critical facility installations. Ultra insertion loss performance ensures headroom for SWDM applications and 100G/400G migrations. Lime green jacketing provides instant OM5 identification in multi-generation fiber plants.
Key Features
- OM5 Wideband Multimode Fiber: 50µm fiber optimized for short-wave division multiplexing (SWDM), supporting 100GBASE-SR4 to 150m and future 400G applications without re-cabling.
- 24-Fiber PanMPO Trunk: Female PanMPO connectors on both ends support 12 duplex channels or two 12-fiber arrays, ideal for spine-leaf architectures and structured trunk-to-cassette deployments.
- HD Flex Small-Diameter Cable: Uses 30-40% less pathway space than legacy trunk cables, critical for overhead ladder rack and dense bundle installations where every cubic inch counts.
- Ultra Insertion Loss Grade: Factory-terminated and tested to deliver <0.35 dB max insertion loss per connection, preserving link budget for challenging runs and high-speed optics.
- LSZH Jacket: IEC 60332-1 and 60754 compliant Low Smoke Zero Halogen construction meets international building codes for enclosed spaces and reduces toxic gas emission during fire events.
- Method A Polarity: Straight-through key-up-to-key-down orientation aligns with TIA-568-C.0 Annex A standard, enabling predictable cassette-to-trunk patching without adapter modules.
- Integrated Pulling Eye: One-end pulling grip simplifies installation through dense overhead pathways and vertical risers, reducing labor time and connector damage risk during long pulls.
- QuickNet Factory Terminated: Panduit QuickNet assemblies ship pre-terminated, pre-tested with insertion loss test reports, eliminating field termination variability and cutting deployment time by 50-70% vs. field-install systems.
OM5 fiber represents the current endpoint in multimode fiber evolution, adding wideband performance to OM4's 50µm core. Where OM4 delivers 100GBASE-SR4 to 100 meters using four wavelengths around 850nm, OM5's extended bandwidth window (840-950nm) supports short-wave division multiplexing (SWDM) technology that splits each physical fiber into four or more logical channels using discrete wavelengths. This matters in 2026 and beyond because emerging 100G BiDi and 400G DR4 optics rely on SWDM to deliver higher speeds over fewer fibers—reducing the need for 40- or 72-fiber trunks in spine-leaf fabrics. A single 24-fiber OM5 trunk can theoretically support 96 logical channels under SWDM, though current transceiver availability focuses on 100G and 400G applications. The FWUYL7575KAM032's ultra insertion loss grade (<0.35 dB per connection) is critical here: SWDM optics have tighter link budgets than parallel optics, so every tenth of a dB preserved at the trunk level expands usable reach and reduces margin-related intermittent errors. Lime green jacketing provides instant visual identification in mixed-generation plants where OM3 (aqua), OM4 (magenta/aqua), and OM5 (lime) cables coexist during phased upgrades.
The HD Flex cable construction addresses a chronic pain point in modern data centers: pathway congestion. Traditional 24-fiber trunk assemblies often measure 12-14mm in overall diameter; Panduit's HD Flex design reduces this to approximately 8-9mm by using smaller buffer tubes and tighter fiber packing without sacrificing bend radius protection or pull strength. In a typical overhead ladder rack scenario, this 30-40% diameter reduction translates to fitting 60-70% more cables in the same cross-sectional area (cable fill scales with radius squared). For a 100-meter spine run carrying eight 24-fiber trunks—common in a mid-scale leaf-spine design—the space savings allow coexistence with power whips, cable trays, and future expansion bundles without exceeding NEC 40% fill ratio limits. The 32-meter length of the FWUYL7575KAM032 is purpose-built for intra-datacenter horizontal runs: long enough to span end-of-row distribution to mid-row leaf switches (typical 20-25m) with service loop, short enough to avoid the cost and loss penalties of 50m+ assemblies. The integrated pulling eye on one end simplifies installation through J-hooks and basket tray—installers attach pull rope to the eye rather than taping around the connector boot, which risks boot damage and fiber stress at the crimp point.
Low Smoke Zero Halogen jacketing is often misunderstood as a European-only requirement, but LSZH is increasingly mandated in North American installations where fiber pathways share space with HVAC returns, traverse occupied floors, or run through enclosed vertical risers. LSZH compounds produce <0.5% hydrogen chloride when burned (vs. 20-30% for PVC) and generate 60-80% less smoke opacity, critical for egress visibility and fire suppression. The FWUYL7575KAM032 meets IEC 60332-1 (flame propagation), IEC 60754-1 (halogen acid gas content <0.5%), and IEC 61034 (smoke density <60% light obscuration), making it compliant with international building codes including EN 50575 CPR (Construction Products Regulation) Class Cca. Method A polarity ensures that when this trunk connects to a Method A cassette (e.g., Panduit FAP modules or equivalent), Position 1 on the trunk maps to Position 1 on the cassette's duplex output, Position 2 to Position 2, and so forth—transmit and receive pairs align correctly without crossover modules or B-to-A adapters. This straight-through approach simplifies troubleshooting (OTDR testing from either end yields identical fiber order) and reduces adapter count in the link, preserving insertion loss budget. The trunk also ships with Panduit's factory test report documenting per-fiber insertion loss, typically 0.15-0.25 dB depending on connector cleanliness and alignment—well under the 0.35 dB maximum spec and leaving margin for mated connections and in-line splices.
Deploy the FWUYL7575KAM032 in leaf-spine fabrics where 100G or 400G uplinks from leaf switches aggregate at spine switches 25-30 meters away, typically in separate row or end-of-row locations. The 24-fiber count supports twelve duplex 100G connections or six 400G connections (using breakout on switch side) without oversizing to 48-fiber trunks that waste half their capacity in under-subscribed racks. HD Flex construction fits high-density overhead pathways where 12+ trunks converge at spine MDA locations, and LSZH compliance satisfies facility requirements in COLO environments, healthcare data centers, and international deployments where PVC is restricted. The pulling eye and QuickNet factory termination cut installation labor to under 20 minutes per trunk including pathway pull and connector inspection, versus 2-3 hours for field-terminated 24-fiber assemblies using fusion splicing or mechanical splice methods. For integrators managing TIA-942 Rated-3 or Rated-4 datacenter builds where tier certification requires documented component performance, the included test report and RoHS compliance statement close out submittals without custom testing.
