Panduit FWUYL7575KAM072 QuickNet OM5 24-Fiber Trunk Cable Assembly
The Panduit FWUYL7575KAM072 is a factory-terminated 24-fiber OM5 trunk cable assembly engineered for high-density 40/100/400GbE data center backbones. This 72-meter (236.22 ft) PanMPO-to-PanMPO trunk uses wideband multimode OM5 fiber with ultra insertion loss performance, delivering extended reach and shortwave wavelength division multiplexing (SWDM) readiness for next-generation Ethernet switching fabrics. The Low Smoke Zero Halogen (LSZH) jacket meets IEC 60332-3-24 and EN 50399 fire safety standards for enclosed data halls and international installations, while the HD Flex transition design reduces bend radius stress at patch panels and occupies 30-40% less conduit space than conventional trunk assemblies. Method A polarity (key-up to key-up) aligns with TIA-568-C.3 structured cabling architectures for direct mating with duplex LC cassettes, and the integrated pulling eye on one end simplifies installation in overhead ladder rack, under-floor conduit, or vertical riser pathways.
Key Features
- OM5 Wideband Multimode Fiber: 50 µm core supports shortwave WDM across four lanes (850/880/910/953 nm) for 40/100/400G applications with OM4-equivalent reach but quadruple bandwidth capacity
- 24-Fiber PanMPO Trunk: Female PanMPO connectors on both ends for direct mating with FHD cassettes, patch panels, or QSFP transceiver modules without adapter keys
- Ultra Insertion Loss Performance: Factory polished and interferometrically tested to less than 0.35 dB typical IL per connector pair, preserving link budget for extended runs

OM5 wideband multimode fiber extends the multimode roadmap by introducing four-lane shortwave WDM capability (850, 880, 910, 953 nm), effectively quadrupling bandwidth over the same physical infrastructure. While OM4 is specified to 550 meters at 10 Gbps and 150 meters at 40/100 Gbps, OM5 maintains those distances but adds SWDM support for 40GBASE-SR4, 100GBASE-SR4, and emerging 400GBASE-SR8 applications—critical for leaf-spine fabrics, storage-area networks, and hyperscale compute clusters that need to future-proof beyond 100G without ripping out installed fiber. The Panduit FWUYL7575KAM072 trunk delivers ultra insertion loss performance, typically under 0.35 dB per connector pair, which preserves link budget for longer runs or higher-loss passive components downstream such as MTP-to-LC breakout cassettes or mid-span attenuators. Factory polishing and automated end-face inspection eliminate the variability of field terminations—studies show field-terminated MPO connectors average 0.5-0.75 dB insertion loss with wider standard deviation, while factory terminations consistently hit 0.25-0.35 dB. Each trunk ships with insertion loss test data traceable to the assembly serial number, satisfying ISO/IEC 11801 and TIA-568-C.3 performance verification requirements without additional field testing.
The HD Flex transition design reduces the minimum bend radius at the connector boot from the traditional 30 mm down to under 20 mm, allowing tighter routing around patch panel edges, cable managers, and high-density enclosure corners without exceeding the 0.25 dB macro-bend loss threshold specified in TIA-568-C.3. This matters during installation—tight 90-degree turns at the top of a 45U rack or around vertical cable managers can kink standard trunk boots, introducing 0.5+ dB loss that eats into your link budget and may push the channel over the 2.6 dB insertion loss limit for 100GBASE-SR4. The LSZH jacket is mandated in European Union data centers under CPR (Construction Products Regulation) and increasingly preferred in U.S. installations where air-handling plenums, enclosed hot-aisle containment, or co-location facilities require halogen-free materials that won't release hydrochloric acid or toxic fumes during a fire event. LSZH jackets also resist UV degradation and abraision better than PVC in high-temperature environments (up to 70°C continuous), extending service life in legacy data halls without supplemental cooling. The lime cable color follows TIA-598-D color coding for OM5 fiber, ensuring at-a-glance identification during moves, adds, and changes—especially important in mixed OM3/OM4/OM5 environments where pulling the wrong trunk can result in a derated 100 m channel instead of the expected 150 m.
Pre-terminated trunks collapse installation schedules by eliminating the fusion splicing, connector polishing, and per-fiber testing labor that field terminations demand. A 24-fiber trunk at 72 meters would require 48 fusion splices (24 fibers times two ends) and OTDR testing of each fiber pair—typically 4-6 hours of skilled labor for a certified fiber tech, plus the cost of consumables (cleaver blades, fusion splice protection sleeves, cleaning supplies). The FWUYL7575KAM072 arrives ready to mate, cutting that installation window to under 30 minutes for physical routing, securing to cable tray, and a single end-to-end insertion loss verification with a fiber test light or OLTS. The reduced-diameter cable design (30-40% space savings per Panduit engineering data) means you can fit more trunks in the same 4-inch conduit or 6-inch cable tray, deferring the cost of additional pathways as the data center scales from 100G to 400G spine uplinks. The integrated pulling eye on one end allows attachment of pull tape or nylon rope for conduit pulls up to 72 meters without stressing the connector boots—critical for vertical riser runs between floors or long horizontal pulls under raised floor where mid-span access is limited. Without a pulling eye, installers often tape directly to the cable jacket or loop around the connector boots, both of which can exceed the 110-pound maximum pulling tension and damage internal fibers.
Method A polarity (key-up to key-up, also called straight-through polarity) is the dominant architecture for duplex LC breakout cassettes and aligns with TIA-568-C.3 Annex D guidelines for structured cabling using MPO trunks. If you are using Panduit FHD cassettes, Corning Edge cassettes, or equivalent MTP-to-LC modules, this trunk plugs directly into the MPO input port on the cassette and fans out to 12 duplex LC ports (24 fibers) without requiring polarity-flip modules, Type B adapter keys, or crossover patch cords. For 40GBASE-SR4 or 100GBASE-SR4 QSFP transceivers that use parallel optics over 8 or 20 fibers, the Method A trunk mates directly to the transceiver MPO port as long as the transceiver is also pinned for Method A (most Cisco, Arista, and Juniper 40G/100G optics default to Method A; check transceiver datasheet if migrating from legacy Method B installations). The PanMPO connector uses a metal guide pin housing and spring-loaded alignment pins for repeatable insertion loss across 500+ mating cycles, compared to 200-cycle limits on plastic-bodied MPO connectors common in low-cost patch cord assemblies.
The FWUYL7575KAM072 meets ISO/IEC 11801 Class FA and TIA-568-C.3 performance standards for OM5 multimode fiber channels, which specify maximum channel insertion loss of 2.6 dB at 850 nm for distances up to 300 meters (the practical limit for SWDM 100G is 150 m due to modal bandwidth, but insertion loss budget still applies). The LSZH jacket complies with IEC 60332-3-24 (vertical flame propagation), EN 50399 (CPR Euroclass B2ca-s1a,d1,a1), and is RoHS compliant for lead-free, halogen-free materials. The OM5 fiber itself carries TIA-492-AAAD and IEC 60793-2-10 type A1a.3 specifications, which define minimum effective modal bandwidth (EMB) of 3500 MHz·km at 850 nm and 1850 MHz·km across the four SWDM wavelengths. Panduit's QuickNet factory-terminated program includes end-face inspection images, IL test data, and a pulling eye as standard features—details that distinguish engineered trunk assemblies from commodity patch cords marketed as infrastructure trunks. For 40G/100G spine uplinks, storage replication links between primary and DR arrays, or 400G leaf-to-spine fabrics in hyperscale builds, this trunk eliminates the largest source of insertion loss variability (field polishing quality) and replaces it with factory test data, serialized traceability, and a manufacturer warranty tied to the assembly as a system rather than individual components.
