Panduit FWUYL7575KAM018 QuickNet 24-Fiber OM5 Trunk Cable Assembly
The Panduit FWUYL7575KAM018 is an 18-meter (59-foot) factory-terminated trunk cable assembly delivering 24 strands of wideband OM5 multimode fiber in a compact, low-smoke-zero-halogen jacket. Designed for high-density data center spine-leaf architectures and storage area networks, this QuickNet assembly eliminates field termination while providing verified insertion loss and return loss performance out of the box. The lime-colored LSZH jacket meets international flammability standards, and the reduced-diameter construction reclaims 30 to 40 percent of pathway space compared to legacy trunk designs—critical when every rack unit and cable tray inch counts in hyperscale or colocation environments.
Key Features
- 24-fiber OM5 wideband multimode (50 µm core) supports short-wave division multiplexing (SWDM) for 400GBASE-SR4.2 and future 800G applications over extended reach
- Factory-terminated QuickNet assembly ships tested and serialized, eliminating fusion splicing labor and reducing deployment time by up to 70 percent versus field termination
- Small-diameter trunk construction uses 30–40% less conduit and cable tray space, enabling higher fill ratios in congested pathways and simplifying moves-adds-changes
- LSZH (Low Smoke Zero Halogen) jacket meets IEC 60332-1 and IEC 60754 flammability and toxicity requirements for indoor risers, plenums, and international installations
- Lime outer jacket provides instant visual identification in mixed-generation fiber plants (OM3 aqua, OM4 erika violet, OM5 lime) to prevent cross-patching errors
- 18-meter length suits typical row-to-end-of-row or intra-row switch interconnects in structured data center designs without excess slack
- Exceeds ISO/IEC 11801 Edition 2.2, TIA-568-C.3, and TIA-492-AAAD optical performance specifications for OM5 fiber with margin for future 100-meter 400G SR8 applications
- RoHS compliant construction meets EU Directive 2011/65/EU and California Proposition 65 restrictions on lead, mercury, cadmium, and hexavalent chromium
OM5 Wideband Multimode Advantage: OM5 fiber extends the usable spectrum of traditional OM3/OM4 multimode from 850 nm to include the 880–953 nm window, enabling short-wave division multiplexing (SWDM) transceivers to transmit four or eight wavelengths simultaneously over a single fiber pair. This architecture delivers 400 Gb/s over duplex LC connections (400GBASE-SR4.2) at reaches up to 100 meters—twice the distance of OM4 at equivalent data rates—without requiring the cost and complexity of parallel optics (MPO-12 or MPO-16) or single-mode infrastructure. For spine-leaf topologies in mid-sized data centers (under 150 meters leaf-to-spine), OM5 provides a future-proof migration path from 100G to 400G and eventually 800G while reusing existing duplex fiber infrastructure and avoiding the wavelength-dependent loss budget challenges of older OM3 plants. The FWUYL7575KAM018's 24-fiber count supports twelve duplex LC connections, sufficient for a fully populated 12-port 400G line card or mixed 100G/400G uplink configurations.
QuickNet Factory Termination and Testing: Every QuickNet trunk cable assembly ships with connectors installed and polished under controlled factory conditions, then tested for insertion loss, return loss, and end-face geometry per TIA-604-5 (FOCIS-5) and IEC 61300-3-35 standards. Each assembly includes a serialized test report documenting per-fiber performance, providing auditable verification for acceptance testing and Uptime Institute Tier certification submittals. Field termination of 24 fibers typically requires 6–8 hours of fusion splicing labor, consumables (splice trays, furcation kits, heat-shrink), and a controlled work environment; QuickNet assemblies eliminate this entirely, reducing deployment time to under 30 minutes for cable pulling, breakout, and connector mating. This labor arbitrage is especially valuable in retrofit projects with tight cutover windows or in markets with scarce fiber-splicing expertise. The factory-terminated approach also removes the single largest source of optical link failures—improper field termination—delivering lower failure rates and reduced troubleshooting overhead during commissioning.
Small-Diameter Construction for High-Density Environments: Traditional 24-fiber trunk cables use 900 µm tight-buffered fibers in a 12–14 mm outer jacket; the FWUYL7575KAM018 employs reduced-diameter buffering and jacket extrusion to achieve a 30–40 percent smaller cross-sectional area without compromising mechanical protection or bend radius performance. In a 4-inch cable tray with 40 percent fill capacity (per NEC Article 392.22), this size reduction increases usable fiber count from approximately 18 legacy trunks to 28 small-diameter trunks—an additional 240 fibers in the same pathway. For hyperscale operators deploying thousands of fibers per rack row, the space savings directly translate to reduced conduit and tray infrastructure costs and simplified cable management. The smaller diameter also improves airflow in perforated cable trays and under raised floors, reducing the risk of hotspots in high-density compute zones. Installers report easier handling and reduced pull tension during installation, lowering the risk of exceeding the cable's 1,000 N maximum pulling load specification.
LSZH Flammability Rating and International Compliance: The FWUYL7575KAM018's low-smoke-zero-halogen jacket meets IEC 60332-1 (vertical flame propagation), IEC 60754-1 (halogen acid gas content <0.5%), and IEC 61034 (smoke density <60% light obscuration) requirements, making it compliant with LSZH mandates in the European Union, Middle East, Asia-Pacific, and increasingly within U.S. data centers pursuing LEED or WELL Building certifications. During combustion, traditional PVC-jacketed cables release hydrochloric acid gas and dense black smoke that obscures egress routes and corrodes sensitive electronics; LSZH jackets produce minimal smoke and non-toxic combustion products, improving life safety in occupied spaces and reducing equipment damage in the event of fire. The cable also meets UL 1666 (riser) and NFPA 70 (National Electrical Code) plenum requirements when installed in appropriate pathways, though buyers should verify local Authority Having Jurisdiction (AHJ) interpretations of LSZH acceptance for plenum spaces in the United States. For multinational deployments standardizing on a single cable specification, LSZH provides the widest geographic acceptance.
18-Meter Length and Deployment Scenarios: At 59 feet, the FWUYL7575KAM018 is optimized for intra-row switch interconnects, end-of-row (EOR) aggregation switch uplinks, or storage array controller-to-SAN-fabric connections within a single data center pod. In a typical row configuration with 12 racks at 2-meter spacing (24 meters row length), an 18-meter cable reaches from a mid-row top-of-rack switch to an EOR aggregation switch with minimal slack, avoiding the excess cable management burden and signal integrity risks of oversized assemblies. The length also suits modular data center designs (containerized or prefabricated pods) where inter-pod fiber runs are standardized at 15–20 meters. For longer campus or building backbone applications (over 100 meters), Panduit offers the same trunk assembly in extended lengths; for shorter intra-rack connections (under 5 meters), patch cords or breakout harnesses are more appropriate. Buyers planning spine-leaf fabrics should map leaf-switch-to-spine-switch physical distances during design to select the optimal trunk length and avoid daisy-chaining patch cords, which introduce additional loss and failure points.
The FWUYL7575KAM018 is warranted by Panduit for materials and workmanship per the manufacturer's standard terms. It meets ISO/IEC 11801 Edition 2.2 (generic cabling for customer premises), TIA-568-C.3 (optical fiber cabling components), TIA-492-AAAD (OM5 fiber performance), IEC 60793-2-10 Type A1a.3 (multimode fiber characteristics), and RoHS Directive 2011/65/EU (restriction of hazardous substances) compliance requirements. Buyers deploying 400G leaf-spine fabrics, SAN storage consolidation, or hyperscale compute clusters will find this trunk assembly reduces installation labor, pathway congestion, and per-port connectivity cost compared to field-terminated or legacy trunk solutions while maintaining headroom for future 800G migrations.
