Panduit FWUYL7575LAM034 QuickNet 24-Fiber OM5 Trunk Cable Assembly
The Panduit FWUYL7575LAM034 delivers 24 strands of OM5 wideband multimode fiber in a factory-terminated, 34-meter trunk assembly engineered for high-density data center interconnects. OM5 fiber supports short-wavelength division multiplexing (SWDM) across four wavelengths (850/880/910/940 nm), enabling 100GBASE-SR4 and 400GBASE-SR4.2 transmission over multimode infrastructure without the cost and complexity of singlemode deployments. The QuickNet small-diameter design occupies 30 to 40 percent less pathway space than conventional 24-fiber trunks, a critical advantage when conduit fill ratios approach NEC Chapter 9 Table 1 limits or when rack-density mandates leave minimal cable-management clearance. The lime LSZH jacket meets international low-smoke zero-halogen flammability standards for enclosed pathways, and the 34-meter engineered length maps to common row-to-row or building-entry-to-MDA distances in modular data center layouts.
Key Features
- 24-fiber OM5 (50 µm core) rated for 100 m at 100G (100GBASE-SR4) and 150 m at 40G (40GBASE-SR4) using SWDM optics
- 34-meter (111.55 ft) length suits mid-range horizontal distribution between equipment distribution areas or cross-connects
- Small-diameter trunk construction reduces bundle cross-section by 30–40% compared to legacy 24-fiber designs, easing conduit fill and improving airflow around cable trays
- LSZH (Low Smoke Zero Halogen) jacket rated to IEC 60332-1 and IEC 61034, compliant with European EN 50173 and international building codes for enclosed vertical and horizontal pathways
- Factory-terminated with duplex LC connectors on both ends, eliminating field splicing, fusion labor, and insertion-loss variability from hand terminations
- Lime jacket color provides instant visual identification in mixed-fiber environments (OM3 aqua, OM4 erise, OM5 lime) per TIA-598-D color-coding recommendations
- Meets or exceeds TIA-568-C.3, ISO/IEC 11801 Ed. 2.2, TIA-492-AAAD (OM5 performance), IEC 60793-2-10 Type A1a.3, and RoHS 3 material-composition directives
- Pull-proof connector boots and ruggedized furcation points engineered for 25-year installed life in commercial environments
- Each trunk ships with test reports documenting insertion loss, return loss, and length per fiber pair, serialized to the cable assembly for audit-trail traceability
OM5 Wideband Multimode — Future-Proof Bandwidth Without Singlemode Complexity
OM5 fiber extends the OM4 core geometry (50 µm) but tightens the effective modal bandwidth (EMB) specification across four distinct wavelengths instead of two. This wideband characteristic enables short-wavelength division multiplexing, where a single fiber pair carries four parallel data streams at 850, 880, 910, and 940 nm simultaneously. Practical impact: a 100GBASE-SR4 transceiver that previously required eight fibers (four transmit, four receive) on OM3 can run over a single duplex OM5 pair using SWDM optics, cutting fiber count by 75 percent and halving connector real estate on panel faces. For 400G migration, OM5 supports 400GBASE-SR4.2 over duplex LC to 150 meters, whereas OM4 tops out at 100 meters and OM3 at 70 meters. The FWUYL7575LAM034's 34-meter length comfortably handles intra-building distribution scenarios — building-entry facility to main distribution area, MDA to horizontal distribution area, or row-to-row in pod architectures — while maintaining at least 2 dB margin below the IEEE 802.3 14 dB channel-loss budget. Because OM5 maintains full backward compatibility with OM3 and OM4 transmission standards (10G, 40G, 100G over eight fibers), deploying this trunk today protects the investment when optics vendors release SWDM modules for next-generation 800G and 1.6T Ethernet standards currently in IEEE 802.3 working groups. The 50 µm core diameter also simplifies integration with existing OM3/OM4 infrastructure during phased upgrades, avoiding the mode-field diameter mismatches and loss penalties inherent in mixing singlemode and multimode fiber types.
High-Density Installation and Cable-Management Economics
Data center operators upgrading from 10G to 100G face a fiber-count explosion: a single 100GBASE-SR4 link consumes eight fibers (or two duplex pairs) on OM4, compared to two fibers for 10GBASE-SR. In a 40-rack row with dual-homed top-of-rack switches, the trunk count from horizontal to spine can exceed 80 fiber pairs per pathway. Traditional round-jacketed 24-fiber trunks measure 12–14 mm in diameter; the FWUYL7575LAM034's small-diameter construction reduces that to approximately 8.5 mm, cutting cross-sectional area by more than one-third. This reduction directly translates to increased conduit fill margin under NEC Article 770 (40% fill for three or more cables) and improved airflow when cables route through perforated vertical managers or overhead ladder rack. The lime LSZH jacket adds negligible cost over PVC but satisfies IEC 61034 smoke-density and IEC 60754 halogen-content limits, a mandatory requirement in European Union installations and increasingly adopted by North American hyperscalers to mitigate toxic-gas release during fire events. Field deployment time drops because QuickNet trunks arrive pre-cleaned, pre-tested, and ready to plug: no fusion splicer, no cleaver, no alcohol wipes, and no technician certification overhead. Labor savings on a 24-trunk MDA-to-HDA installation typically recover the factory-termination premium in under two hours of avoided field time, and the serialized test reports satisfy SOC 2 and ISO 27001 audit requirements for infrastructure-change documentation without additional contractor-generated paperwork.
Panduit factory-terminates each FWUYL7575LAM034 trunk under controlled cleanroom conditions and validates performance against TIA-568-C.3 insertion-loss limits (0.75 dB maximum at 850 nm) and return-loss minimums (−20 dB) before shipment. The assembly carries cULus listing for plenum and riser applications when installed per NEC Article 770, and the RoHS-compliant bill of materials satisfies European Union Directive 2011/65/EU Annex II material restrictions for lead, mercury, cadmium, and hexavalent chromium. Specify this trunk when the installation requires a mid-range (30–40 m) 24-fiber link, pathway space is constrained, and the infrastructure must support both current 100G optics and future SWDM-based 400G migration without a forklift upgrade. For shorter distribution (under 15 m), consider Panduit's 15 m variant; for backbone runs exceeding 100 m, evaluate OM5 lengths to 150 m or transition to OS2 singlemode trunks for campus-scale distances.
