Panduit FWUYL7575KNM019 OM5 24-Fiber QuickNet Trunk Cable Assembly
The Panduit FWUYL7575KNM019 is a 19-meter, 24-fiber OM5 trunk cable assembly engineered for high-density data center deployments where space, speed, and insertion-loss margin drive design decisions. Built on QuickNet™ factory-terminated architecture, this PanMPO-to-PanMPO trunk delivers 30-40% smaller diameter than legacy OM3/OM4 cable bundles, freeing critical pathway capacity in overhead ladder rack and 4-inch horizontal trays. The OM5 wideband multimode fiber supports both legacy 850nm optics and next-generation SWDM (short wavelength division multiplexing) across 850-953nm, enabling 400GBASE-SR4.2 and 800G applications at extended reach without infrastructure replacement. LSZH jacket construction meets international fire-safety mandates and provides plenum-equivalent protection in enclosed air-handling spaces where traditional plenum rating isn't practical for high-count fiber.
Key Features
- OM5 wideband multimode fiber (50/125μm) — Supports legacy 10G/40G/100G at 850nm plus 400G/800G SWDM optics across 850-953nm wavelengths for future-proof infrastructure
- 24-fiber trunk configuration — Enables 2x 400G QSFP-DD breakout or 4x 100G QSFP28 patching in structured leaf-spine architectures
- PanMPO Female HD Flex connectors — High-density footprint reduces panel congestion; female pinning on both ends for Method A polarity compliance
- Ultra Insertion Loss specification — Tighter-than-TIA loss budget (typically <0.35 dB per connector) preserves margin for multi-tier fabric topologies and future transceiver generations
- Method A polarity — Straight-through fiber mapping per TIA-568-C.0 Annex B; industry-standard trunk-to-trunk and trunk-to-breakout compatibility
- 19-meter cable length — Covers cross-aisle, inter-row, or zone-to-zone patching distances in medium-to-large data center halls
- LSZH jacket — Low smoke zero halogen construction for fire-safety compliance in enclosed spaces, international facilities, and ASHRAE A3/A4 filtered-air environments
- Lime jacket color — OM5 color-code per TIA-598 for instant visual identification in mixed-mode (OM3/OM4/OM5) fiber plants
- 30-40% reduced diameter — QuickNet HD Flex trunk cables occupy less cable-tray fill and vertical manager space than traditional round-jacketed MTP trunks
OM5 wideband multimode fiber extends the multimode roadmap beyond OM4's 100G-per-wavelength ceiling by introducing four-channel SWDM operation across 850, 880, 910, and 940nm windows. This means a single 24-fiber trunk can carry 800G aggregate bandwidth (4x 200G lanes per 12-fiber array) over duplex or parallel optics, all within the 100-meter reach class that defines data center scale. The Ultra Insertion Loss specification — a Panduit-exclusive performance tier — guarantees each PanMPO connector pair will dissipate less than 0.35 dB typical, well below the TIA-568-C.3 maximum of 0.75 dB. In a two-tier spine-leaf fabric where a single 400G channel traverses four mated connector pairs (leaf panel → trunk → spine panel → patch cord), that delta compounds: standard-grade connectors might burn 2.4 dB of your 3.5 dB budget, while Ultra IL holds loss to 1.4 dB, preserving 2.1 dB for fiber attenuation, splice losses, and future technology margin. Method A polarity — also known as straight-through — maps fiber 1 on connector A to fiber 1 on connector B, the configuration mandated by TIA-568-C.0 Annex B for trunk cables. When you mate this trunk to a Method A breakout cassette or another Method A trunk, the Tx lanes on one switch automatically align with the Rx lanes on the opposite switch, eliminating the crossed-fiber headaches that plagued early MPO deployments. The HD Flex connector shell is mechanically narrower than legacy MTP housings, enabling 20% denser panel layouts when used with Panduit's HD Flex cassettes and patch panels.
A 19-meter trunk length lands in the sweet spot for inter-row and cross-zone data center patching. If your rows are on 6-meter centers and you're running overhead, 19 meters accommodates two-row hops plus vertical drops and service loops without slack-coil waste. The reduced-diameter construction matters more than the spec sheet implies: a traditional round-jacketed 24-fiber MTP trunk runs 8-10mm OD; Panduit's QuickNet HD Flex trunk measures closer to 6mm, a 40% reduction in cross-sectional area. When you're filling a 4-inch-wide vertical manager or a 12-inch ladder-rack rung with 60 trunks, that difference is the gap between a clean install and a bulging, hard-to-trace rat's nest. LSZH jacket material is mandatory under IEC 60332-3 and EN 50399 for European and Asia-Pacific deployments, and it's increasingly specified in North American facilities where traditional plenum-rated cable (rated for HVAC-shared air return) doesn't apply — enclosed server halls with dedicated CRAC units, modular data centers, and ASHRAE A3/A4 filtered-air environments where particulate and corrosive-gas exposure demand sealed air paths. LSZH produces less than 0.5% HCl during combustion and emits 30% of the smoke volume compared to PVC or FEP jackets, critical when every second of visibility counts during emergency egress. The QuickNet system's factory-terminated approach eliminates field fusion splicing, the traditional bottleneck in high-fiber-count deployments. Instead of a two-person fusion crew spending 90 minutes per 24-fiber trunk (cleaving, splicing, testing, and enclosure buildup), an installer simply verifies end-face cleanliness with a microscope, mates the connectors, and moves to the next trunk — three minutes per link. This 30:1 time advantage compounds across a 2,000-fiber spine build, collapsing what used to be a six-week fusion project into a three-day plug-and-play installation.
This trunk assembly meets ISO/IEC 11801 Class OM5, TIA-568-C.3 Category OM5, TIA-604-5 (FOCIS-5) MPO connector geometry, IEC 60793-2-10 type A1a.3 wideband multimode fiber, and RoHS material restrictions. The Ultra Insertion Loss performance tier isn't a published standard — it's a Panduit manufacturing specification backed by automated factory testing of every connector, guaranteeing the loss headroom that makes the difference between a marginal link that fails at 70°C under full load and a robust channel with 6 dB margin at end-of-life. Lime jacket color per TIA-598 provides instant OM5 identification in mixed-fiber environments where OM3 aqua and OM4 magenta trunks coexist during phased upgrades. When you're building out a 400G spine-leaf fabric and every dB of loss margin determines whether you can deploy cost-effective SR8 optics or must step up to 10km LR8 transceivers at 4x the price, factory-terminated OM5 trunks with guaranteed Ultra IL remove the field-termination gamble and put channel performance in the spec sheet, not the installer's hands.
