Panduit FWUYL7575KNM038 QuickNet 24-Fiber OM5 Trunk Cable Assembly
The Panduit FWUYL7575KNM038 is a 24-fiber OM5 wideband multimode trunk cable assembly engineered for high-density data center and enterprise network deployments requiring extended reach and rapid infrastructure standup. At 38 meters (124.67 feet), this QuickNet trunk delivers the length needed for cross-aisle or inter-rack connections in medium to large data halls while maintaining OM5's 100-gigabit and short-wave wavelength-division multiplexing (SWDM) capabilities. The reduced-diameter cable construction consumes 30 to 40 percent less pathway space than legacy trunk designs, critical when you're filling cable trays, overhead ladder rack, or under-floor conduit in colocation facilities where every cubic inch costs money. LSZH jacketing meets low-smoke zero-halogen flammability requirements for occupied spaces and international installations. Lime jacket color provides instant visual identification during moves, adds, and changes, reducing the risk of accidental disconnection in densely populated patch fields.

OM5 wideband multimode fiber represents a step-change in data center cabling economics. Unlike OM3 and OM4, which rely on parallel optics (multiple fibers per direction) to scale beyond 10 Gbps, OM5's extended effective modal bandwidth at 953 nm enables short-wave wavelength-division multiplexing. In practical terms, SWDM transceivers transmit four 25 Gbps wavelengths over a single duplex OM5 pair to deliver 100 Gbps, cutting the fiber count in half compared to 100GBASE-SR4's eight-fiber requirement. This trunk's 24-fiber configuration supports twelve duplex OM5 links or six 100G SWDM channels—enough for a fully redundant spine-leaf connection between two top-of-rack switches and a pair of aggregation switches in a leaf-spine fabric. The 38-meter length covers typical data center row depths (12–15 meters from rack to end-of-row aggregation point) with margin for vertical rise, pathway routing around hot/cold aisle containment, and strain relief loops at termination points. Panduit specifies 100GBASE-SR4 reach of 150 meters over OM5 at 850 nm, and the shorter SWDM wavelengths maintain that reach envelope, so this trunk fits comfortably within the link budget for intra-data-hall connections. Field testing via OTDR or light source/power meter becomes straightforward: OM5's 50-micron core and 850 nm launch condition match OM3/OM4 test procedures, and the factory-installed MPO or LC connectors (check product variant for connector type) eliminate the insertion-loss variability introduced by field terminations.
QuickNet factory-terminated trunks solve the single biggest fiber deployment bottleneck: labor. A trained technician can pull and terminate a 24-fiber bulk cable in 6–8 hours including splicing, polish, and test. This trunk reduces that window to 45–90 minutes—pull the cable, mate the connectors, verify continuity, done. The time savings compound in large deployments: a 200-rack hyperscale buildout requiring 400 trunks represents 3,200 labor-hours saved, equivalent to two full-time techs for ten weeks. The reduced-diameter construction addresses the second deployment constraint: pathway congestion. Legacy 24-fiber trunks often measure 12–14 mm in diameter; Panduit's small-diameter design typically runs 8–10 mm, shrinking cross-sectional area by 30–40 percent. In a 4-inch cable tray filled to the NEC's 50 percent capacity limit, that difference translates to 60–80 additional trunks in the same footprint. The pathway space savings also improve thermal management—tightly packed cables block airflow, creating hot spots in overhead trays that radiate heat into the data hall. Thinner trunks leave more air gaps, reducing the thermal load on CRAC units and cutting cooling costs. The LSZH jacket is non-negotiable for installations in occupied buildings, international deployments, or any facility subject to IBC/NFPA plenum requirements. In a fire scenario, PVC-jacketed cables release hydrochloric acid and dense smoke; LSZH jackets emit minimal smoke and no halogenated acids, preserving visibility for evacuation and reducing corrosive damage to servers and network gear. Insurance underwriters and local AHJs (authorities having jurisdiction) increasingly mandate LSZH in data centers and telecom spaces, and this trunk's LSZH rating eliminates the need for costly rework if a future audit or tenant requirement triggers a cable replacement.
Compliance with TIA/EIA-568-C.3, ISO/IEC 11801, TIA-492-AAAD (OM5 fiber performance), and FOCIS-5 (MPO connector geometry) ensures interoperability with Cisco, Juniper, Arista, Dell, HPE, and other Ethernet switch vendors' optics modules. Panduit factory tests each trunk for insertion loss, return loss, and polarity per TIA standards, and ships with a test report showing actual measured values—critical when you're validating link budgets for 40G/100G/400G optics that have tighter loss budgets than 10G. The lime jacket color follows TIA-598-D recommendations for OM5 identification, preventing accidental cross-connection with OM3 (aqua) or OM4 (erika violet) infrastructure during maintenance. This trunk ships as a single unit (package quantity: 1) with no carton consolidation, simplifying inventory management and kitting for phased deployments where you stage materials rack-by-rack rather than ordering bulk pallets.
