Panduit FWUYL7575KNM023 QuickNet OM5 24-Fiber Trunk Cable Assembly
The Panduit FWUYL7575KNM023 is a 23-meter QuickNet trunk cable assembly engineered for high-density data center infrastructures demanding 100G, 400G, and next-generation short-wavelength-division-multiplexing (SWDM) readiness. Built on OM5 wideband multimode fiber, this 24-fiber trunk delivers PanMPO-to-PanMPO female connectivity in a low-smoke-zero-halogen (LSZH) jacket with HD Flex construction—reducing pathway congestion by 30 to 40 percent compared to legacy bundle designs while meeting international plenum and riser flammability mandates. Ultra insertion loss specifications and Method A polarity ensure reliable 400GBASE-SR8 parallel optics deployments and future SWDM migrations with minimal re-cabling.
Key Features
- OM5 Wideband Multimode Fiber: 50µm core supporting 100GBASE-SR4, 400GBASE-SR8, and SWDM (4 wavelengths: 850/880/910/950 nm) for 4× the bandwidth density of OM4 in short-wavelength applications.
- 24-Fiber Capacity: Twelve duplex lanes or dual 12-fiber MPO breakouts; supports eight 50G PAM4 lanes (400G-SR8) or twelve 25G NRZ lanes (100G-SR4 with headroom).
- PanMPO Female-to-Female Connectors: Panduit's MPO/MTP-compatible interface with Method A (straight-through, key-up-to-key-down) pinout for TIA-568-C.3 compliant structured cabling.
- Ultra Insertion Loss: Factory-terminated to tighter-than-standard IL tolerances (typically ≤0.35 dB per mated pair), preserving link budget for extended 400G reach and multi-tier spine-leaf topologies.
- HD Flex Construction: Reduced-diameter trunk with bend-insensitive fiber; occupies 30–40% less conduit and cable-tray space than conventional 24-fiber bundles, critical for congested hot-aisle/cold-aisle pathways.
- LSZH Jacket (Lime): Low-smoke-zero-halogen outer sheath meets IEC 60332-3 and UL 1685 FT4 vertical-tray flame-test requirements; lime color conforms to TIA-598-C OM5 identification standard.
- 23-Meter Pre-Terminated Length: Eliminates field splicing and polishing; drop-in ready for typical intra-row aggregation-switch-to-spine distances in medium-scale PODs.
- QuickNet Platform Integration: Part of Panduit's factory-tested trunk ecosystem; each assembly ships with end-to-end IL/RL test reports traceable to NIST standards.
OM5 fiber—specified in TIA-492-AAAD and IEC 60793-2-10 type A1a.3—extends multimode's relevance into the 400G era by adding 880 nm and 910 nm wavelengths to the traditional 850 nm window. While OM4 delivers 4700 MHz·km effective modal bandwidth (EMB) at 850 nm, OM5 trades slightly lower single-wavelength EMB (3500 MHz·km at 850 nm) for wideband performance: 1850 MHz·km at 950 nm enables coherent four-wavelength SWDM transmission over duplex LC or dual-fiber MPO breakouts. In practical terms, a single OM5 duplex pair can carry 100GBASE-DR (4×25G PAM4 SWDM) where OM4 would require eight fibers and SR4 parallel optics. For this 24-fiber trunk, that headroom means an integrator can design a 12-lane 100G fabric today, then migrate six of those lanes to SWDM 100G tomorrow—doubling effective port density without re-pulling cable. The PanMPO connector system uses a 12-fiber or 24-fiber ferrule with push-pull latching and removable housing; Method A polarity (pin 1 transmit to pin 1 receive at far end) is the TIA-568-C.3 default for duplex breakout cassettes and requires key-up-to-key-down mating or a polarity-reversing patch panel. Panduit's Ultra IL specification typically holds mated connector loss below 0.35 dB (vs. the 0.5 dB industry maximum), recovering 0.3 dB per link—enough to extend 100G-SR4 reach from 70 m to 100 m on OM4, or to accommodate an additional switch tier in three-stage Clos fabrics. The FWUYL7575KNM023's factory geometry inspection, end-face polish to IEC 61300-3-35 standards, and automated IL testing at 850/1300 nm ensure first-time interoperability with Cisco, Arista, Juniper, and Mellanox 100G/400G QSFP transceivers.
High-density data center deployments face three persistent constraints: pathway fill ratio (NEC 300.17 limits conduit to 40% fill), minimum bend radius (exceeding spec causes macrobend attenuation spikes), and airflow obstruction in overhead ladder-rack runs. Traditional 24-fiber trunks bundle twelve duplex LC cables or six 4-fiber ribbons into a 15–18 mm outer diameter; at 40% fill, a 1-inch EMT conduit accommodates only two such trunks. The FWUYL7575KNM023's HD Flex design uses rollable ribbon or tight-buffered-tube construction with bend-insensitive G.657.A2 fiber, achieving a 9–11 mm outer diameter and 15 mm minimum bend radius (10× the cable diameter). That dimensional reduction allows four trunks per 1-inch conduit, or closer bundling in vertical-mount cable managers without exceeding the 38 mm (1.5U) depth budget of high-density patch panels. The LSZH jacket—formulated with mineral-filled polyolefin or halogen-free EVA compounds—produces <0.5% hydrogen chloride and <50% light-transmission loss (smoke density) when burned per IEC 61034, meeting European CPR Euroclass Cca requirements and increasingly common North American specs for enclosed-return-air plenums (UL 2043). Lime coloring (Pantone 802C equivalent) provides instant visual differentiation from OM3 (aqua) and OM4 (erika violet) legacy infrastructure during phased migrations—critical when a single wrong cross-connect can black-hole a 400G uplink. For a typical deployment scenario: spine switches at end-of-row locations feeding leaf switches 20–25 meters away in a hot-aisle-contained POD. The 23 m length provides 2–3 m of service loop at each end for future moves-adds-changes, avoiding the 15% insertion-loss penalty and week-long lead time of field-spliced extensions. Installers route the trunk through vertical J-hooks (spaced per BICSI TDMM guidelines at ≤1.5 m intervals), terminate into 1U 144-fiber QuickNet cassette panels (using Panduit's FAP snap-in modules), then break out to duplex LC via Method A polarity cassettes. Each 24-fiber trunk supports twelve 100G-SR4 server connections or three 400G-SR8 uplinks; scaling to 48 servers per rack requires only two trunks and two cassette panels—versus 96 individual LC-LC cables and the associated dress-and-label labor.
Compliance with TIA-604-5 (FOCIS-5) ensures mating-force compatibility with generic MPO and Corning MTP® connectors, while ISO/IEC 11801 Ed. 3 OF-500 (OM5) certification provides European procurement alignment. The QuickNet factory test process includes automated IL measurement at 850 nm and 1300 nm (capturing both OM5's short-wavelength SWDM window and the 1310 nm reference), return-loss verification (≥-20 dB typical), and end-face geometry inspection per IEC 61300-3-35 interferometry—radius-of-curvature, apex offset, and fiber height documented on per-assembly test sheets. For integrators managing TIA-942 Rated-3 or Rated-4 data center builds, this traceability satisfies third-party commissioning requirements without field testing every connector. RoHS compliance (lead-free solder, cadmium-free pigments) meets EU and California REACH restrictions; the halogen-free jacket aligns with GREENGUARD and LEED credit EQ4.5 low-emitting-materials criteria for occupied telecom rooms.
