Panduit FWUYL7575KAM027 OM5 24-Fiber PanMPO Trunk Cable Assembly
The Panduit FWUYL7575KAM027 is a 27-meter OM5 trunk cable assembly engineered for high-density data center spine-leaf architectures and 40G/100G migration paths. This 24-fiber QuickNet™ trunk terminates with PanMPO female connectors on both ends, delivering Method A polarity in a low-smoke zero-halogen (LSZH) jacket rated for enclosed pathways and international fire codes. The lime cable jacket provides instant visual identification in dense cable trays, while the HD Flex construction reduces bundle diameter by 30-40% compared to legacy tight-buffered designs—critical when retrofitting existing conduit or maximizing airflow in hot-aisle containment.
Key Features
- OM5 wideband multimode fiber supports SWDM (short-wave wavelength division multiplexing) for 40G/100G over extended reach
- 24-fiber PanMPO female-to-female trunk with Method A (straight-through) polarity for direct switch-to-switch or switch-to-panel interconnects
- Ultra insertion loss specification ensures margin for 100GBASE-SR4 and emerging 200G/400G SR4.2 applications
- LSZH jacket meets IEC 60332-3-24 and international building codes for non-plenum enclosed spaces, equipment rooms, and riser pathways
- HD Flex small-diameter cable construction occupies 30-40% less tray space than standard 2.0mm buffered trunks
- Factory-terminated with integrated pulling eye on one end—eliminates field termination labor and ensures consistent sub-0.35dB connector performance
- Lime jacket color per TIA-598-D fiber identification standard (OM5 = lime green)
- 27-meter (88.58 ft) length accommodates cross-row or cross-zone data center runs without mid-span splice points
OM5 fiber is the latest-generation multimode standard (TIA-492-AAAD, IEC 60793-2-10 A1a.3), optimized for short-wave wavelength division multiplexing across four distinct wavelengths (850nm, 880nm, 910nm, 940nm). Unlike OM3/OM4 deployments limited to a single 850nm channel, OM5 enables 40GBASE-SR4 and 100GBASE-SR4 transceivers to multiplex four parallel lanes over a single fiber pair—doubling effective cable plant capacity without ripping out existing pathways. The 50-micron core supports 100-meter channel lengths at 100G and 150-meter links at 40G, covering 95% of intra-data-center distances. The PanMPO connector interface (Panduit's MTP-compatible variant) is a 12-fiber or 24-fiber array connector that replaces twelve or twenty-four individual LC duplex connections with a single plug-in module—reducing port density requirements on spine switches and allowing 1U patch panels to support 144+ fiber terminations. This trunk uses the female pinned variant on both ends, requiring a male PanMPO adapter or bulkhead in the signal path; Method A polarity means fiber position 1 on end A maps to position 1 on end B (straight-through), the default for switch-to-panel links when using Method B crossover panels. Ultra insertion loss (UIL) grading guarantees each connector interface stays below 0.35dB typical (0.50dB max)—critical for 100G optics running near the 1.9dB IEEE 802.3bm loss budget, where every tenth of a dB counts when factoring in panel adapters, jumpers, and aging margin.
The HD Flex cable construction uses 200-micron tight-buffered fibers in a reduced-diameter jacket (approximately 6.6mm OD for 24F) compared to 9-11mm distribution-style cables, cutting cross-sectional area by half and allowing twice the cable count in basket tray or overhead ladder rack. In retrofit projects where existing 4-inch conduit is already at 40% fill per NEC 300.17, switching from legacy round trunk designs to HD Flex can recover 30% usable space—enough to add a second diverse path without new pathway construction. The LSZH jacket is a halogen-free flame-retardant compound that produces minimal smoke and no corrosive hydrochloric acid gas during combustion, meeting IEC 60332-3-24 Category C vertical flame propagation and IEC 61034 light-transmittance requirements. While not a plenum-rated (CMP) cable, LSZH is the required standard in EMEA/APAC markets and increasingly specified in US equipment rooms, battery vaults, and under-floor pathways where PVC smoke toxicity is a life-safety concern. The lime jacket color is mandated by TIA-598-D for OM5 fiber, providing instant visual differentiation from aqua OM3, violet OM4, and yellow single-mode trunks during maintenance—critical in lights-out facilities where a technician pulling the wrong fiber can black out a production SAN. The factory-installed pulling eye on one end is a reinforced Kevlar loop rated for 110-220N tension, allowing installers to pre-lube the trunk and pull it through J-hooks or innerduct in a single motion without stressing the connector bodies or risking fiber kinking at tight bend points. Panduit specs a 20x cable diameter minimum bend radius under no-load conditions (132mm for this assembly), tightening to 30x during pulls—still half the bend radius of armored or breakout-style trunks, reducing pathway elevation changes and eliminating costly radius boxes in vertical riser shafts.
This 27-meter length is purpose-built for inter-row or cross-zone data center links—longer than the 15m standard for intra-rack leaf-to-spine connections but shorter than the 100m campus backbone runs that justify single-mode infrastructure. In a typical deployment, this trunk runs from a top-of-rack leaf switch in Row A to an end-of-row spine aggregation point 20-25 meters away (accounting for vertical rise to overhead tray, horizontal run, and drop to equipment), with 2m service loop reserved at each end per BICSI DCIM best practices. The assembly ships as a single piece with both connectors pre-installed and insertion-loss tested at the factory, eliminating the field labor, test equipment, and certification paperwork associated with fusion splicing or mechanical terminations. It meets TIA-568-C.3 structured cabling performance requirements, ISO/IEC 11801 international premises standards, and TIA-604-5 (FOCIS-5) connector geometry specs, ensuring interoperability with Cisco, Juniper, Arista, and Mellanox 40G/100G optics modules regardless of transceiver vendor. The RoHS-compliant construction contains no lead, mercury, or hexavalent chromium, satisfying EU WEEE directives and increasingly common procurement sustainability requirements. For integrators deploying 100G spine fabrics, refreshing 10G leaf-spine networks to 40G, or future-proofing new builds for 200G/400G optics roadmaps, this trunk delivers the port density, physical space efficiency, and performance margin that separates a clean five-year migration from a forklift upgrade three years in.
