Panduit FWUYL7575KNM050 OM5 24-Fiber Trunk Cable Assembly
The Panduit FWUYL7575KNM050 is a 50-meter QuickNet pre-terminated trunk cable assembly engineered for high-density data center installations running 40GBASE-SR4, 100GBASE-SR4, and 400GBASE-SR8 Ethernet over OM5 wideband multimode fiber. Twenty-four 50 μm OM5 fibers terminate to PanMPO female connectors on both ends with Method A polarity and ultra insertion loss performance, allowing twelve duplex 40G or 100G connections—or three 400G connections—in a single pull. The HD Flex low-profile trunk design uses 30–40% less pathway space than legacy 24-fiber assemblies, a critical advantage when filling overhead ladder rack or under-floor conduit to capacity. LSZH jacketing meets plenum fire and smoke requirements for installation above suspended ceilings or in air-handling spaces without additional conduit, and the lime jacket provides instant visual confirmation of OM5 media during moves, adds, and changes.
Key Features
- OM5 wideband multimode fiber supports 40G/100G SR4 up to 150 meters and enables four-wavelength shortwave WDM (SWDM) for 400G applications
- 24 fibers in PanMPO female-to-female configuration deliver twelve duplex channels or three 400GBASE-SR8 links per trunk
- HD Flex cable construction reduces cross-sectional diameter by 30–40%, freeing congested pathways and improving airflow in overhead spaces
- Method A polarity matches industry-standard patch panel layouts; ultra insertion loss spec ensures link budgets remain within IEEE 802.3 and 100GBASE-SR4 limits even after multiple mating cycles
- Low Smoke Zero Halogen (LSZH) jacket rated for plenum installation without additional raceway; meets IEC 60332-3 flame propagation and IEC 61034 smoke density limits
- Lime jacket color provides instant visual identification of OM5 media per TIA-598-D fiber color coding standards
- Factory-terminated and factory-tested QuickNet assembly eliminates field splicing, reducing deployment time from days to hours and removing variability from connector endface geometry
- 50-meter length suits typical row-to-end-of-row or intra-room horizontal runs in modular data centers and colocation facilities
Data center operators deploying 100 Gigabit Ethernet leaf-spine fabrics or upgrading edge-of-rack switches to 40G uplinks face two persistent infrastructure challenges: physical space and future bandwidth headroom. A fully populated 48-port 100GBASE-SR4 spine switch requires 48 twelve-fiber MTP trunks—576 fibers—back to a centralized patching zone, and legacy OM3 or OM4 trunk cables often consume so much conduit fill that adding a second parallel fabric becomes impossible without ripping out existing cable. The FWUYL7575KNM050 addresses both constraints. OM5's wideband performance supports shortwave wavelength division multiplexing, allowing a single duplex fiber pair to carry 100 Gbps today and scale to 400 Gbps tomorrow when optics are swapped—no re-cabling required. The HD Flex reduced-diameter construction means you can fit 40% more trunks in the same 4-inch conduit or overhead J-hook run, preserving pathway capacity for growth. For retrofit projects in operational data centers where outage windows are measured in minutes, pre-terminated trunks eliminate the need to bring fusion splicers, cleaning stations, and OTDR test sets into a live environment; installers pull the assembly, plug both ends, verify continuity with a visual fault locator, and the link is production-ready.
Method A polarity is the de facto standard for enterprise and service provider networks because it allows direct key-up-to-key-up mating between two MTP connectors while maintaining correct transmit-to-receive fiber mapping on duplex breakout legs. In a typical deployment, this trunk runs from a spine switch equipped with 100GBASE-SR4 QSFP28 transceivers (using MTP singlemode or multimode interfaces) to a patch panel in a meet-me room or main distribution area. At the panel, MTP-to-LC breakout modules convert the trunk into twelve duplex LC connections, each carrying a dedicated 100G channel to leaf switches or storage arrays. The ultra insertion loss specification—tighter than the standard 0.35 dB TIA-568 limit—ensures that even after panel connections, jumper mates, and transceiver interfaces, total channel loss remains well below the 1.9 dB budget for 100-meter 100GBASE-SR4 links or the 1.5 dB budget for OM5 SWDM applications. This margin is critical in environments where connectors may be mated and un-mated during troubleshooting or when optics are moved between ports during capacity rebalancing.
Low Smoke Zero Halogen jacketing is a non-negotiable requirement in many international markets and increasingly specified in U.S. hyperscale and colocation facilities. During a fire, PVC-jacketed cables release hydrochloric acid and dense black smoke that obscures exit paths and damages sensitive electronics; LSZH materials produce minimal smoke opacity and no corrosive halogens, protecting both personnel and equipment. This trunk meets IEC 60332-3 Category C vertical flame propagation limits and IEC 61034 smoke density limits (light transmittance ≥60%), satisfying the most stringent building and data center fire codes including NFPA 75 and IEC 61000-4-2. The lime jacket color follows TIA-598-D Annex F recommendations for OM5 fiber identification, allowing technicians to distinguish OM5 trunks from older OM3 (aqua) or OM4 (eero violet/aqua) infrastructure at a glance during audits or when tracing links in densely packed overhead pathways. This visual distinction prevents accidental cross-connection of OM5-optimized 400G SWDM optics into OM3 links, which would result in bit error rates above forward error correction thresholds and intermittent link flapping.
QuickNet factory termination delivers mechanical and optical performance that field terminations cannot match. Each PanMPO connector is assembled in a controlled cleanroom environment, with endfaces polished to sub-50nm surface finish and inspected under interferometry to verify compliance with IEC 61755-3-31 geometry specifications for radius of curvature, apex offset, and fiber height. Insertion loss and return loss are tested on all twenty-four fibers at 850nm and 1300nm wavelengths, and test results are serialized to the trunk's pull-box label, providing a baseline for acceptance testing and future troubleshooting. This level of quality control is unattainable with field-installable MTP connectors, which rely on hand cleaving, manual epoxy injection, and portable polishing—processes that introduce endface defects, insert variability into loss budgets, and extend installation schedules by hours per trunk. For integrators bidding fixed-price data center deployments, pre-terminated trunks shift risk from labor (unpredictable rework cycles, technician skill variability) to material (known cost, factory-warranted performance), improving job costing accuracy and protecting margin.
The 50-meter length is optimized for intra-building horizontal distribution: row-to-row connections in pod-based modular data centers, edge-of-row aggregation switches back to core routers in raised-floor facilities, or storage area network links between compute racks and all-flash arrays in converged infrastructure deployments. OM5 fiber provides 150-meter reach at 100 Gbps (100GBASE-SR4) and 400-meter reach at 40 Gbps (40GBASE-SR4), so this trunk leaves substantial link budget headroom even after accounting for patch panel insertion loss, jumper loss, and connector degradation over time. For 400GBASE-SR8 applications using SWDM optics, OM5 supports 100-meter links—double the reach of OM4 at the same data rate—allowing centralized patching architectures that would otherwise require mid-span active optical repeaters. This extended reach simplifies network topology, reduces points of failure, and eliminates the need for powered equipment in overhead pathways where AC outlets and cooling are unavailable.
This trunk cable assembly ships as a single unit with protective dust caps on both MTP connectors and is packaged in a pull-box designed to prevent kinking or excessive bend radius during installation. The assembly is RoHS compliant, TIA/EIA-568-C.3 verified, and meets ISO/IEC 11801 international cabling standards as well as TIA-492-AAAD fiber geometry specifications for 50 μm multimode. Panduit's manufacturing traceability allows each trunk to be traced back to fiber lot, connector batch, and assembly line station, satisfying change-control and audit requirements in regulated industries including finance, healthcare, and government. Deployment in mission-critical 100G and 400G Ethernet fabrics where 30–40% space savings, LSZH fire safety, and OM5 future-proofing are non-negotiable infrastructure requirements.
