Panduit FWUYL7575LNM017 QuickNet™ 24-Fiber OM5 Trunk Cable Assembly
The Panduit FWUYL7575LNM017 is a 24-fiber OM5 wideband multimode trunk cable assembly engineered for high-density datacenter spine-leaf architectures demanding 100 Gigabit and 400 Gigabit Ethernet readiness with minimal pathway congestion. Measuring 17 meters (55.77 feet), this QuickNet™ pre-terminated assembly bridges inter-row distribution frames, cross-aisle connections, or raised-floor equipment racks where extended reach beyond typical 10-meter patch cords is required but permanent fusion splicing introduces unacceptable deployment delays. OM5 lime-jacketed 50-micron multimode fiber supports shortwave wavelength division multiplexing (SWDM) for 100GBASE-SR4 and 400GBASE-SR16 transmission over distances up to 150 meters at 850nm, while the small-diameter trunk design occupies 30 to 40 percent less conduit and cable tray space compared to legacy OM3 or OM4 assemblies with equivalent fiber count—a critical advantage when retrofitting existing pathways or maximizing airflow in hot-aisle containment zones. Factory-terminated connectors eliminate field polishing labor and deliver insertion loss consistency below 0.35 dB per mated pair, and the LSZH (Low Smoke Zero Halogen) jacket meets IEC 60332-3-24 flame propagation limits and IEC 61034-2 smoke density restrictions mandated by international building codes for plenum-equivalent or enclosed-space installations.
Key Features
- OM5 wideband multimode fiber certified for 100GBASE-SR4 and 400GBASE-SR8/SR16 at distances up to 150m, future-proofing spine-leaf fabrics for 800G migration
- 24-fiber count in small-diameter trunk construction reduces pathway fill by 30-40% vs. traditional assemblies, enabling higher port density in congested cable trays and under-floor grids
- QuickNet™ factory termination with pre-tested connectors ships ready to install—no field fusion splicing, polishing, or OTDR verification required on-site
- 17-meter (55.77 ft) length spans inter-row distances in modular datacenter layouts, eliminating the need for intermediate splice enclosures between end-of-row aggregation switches and core distribution frames
- LSZH jacket compliant with IEC 60332-3-24 and IEC 61034-2 for plenum-equivalent fire safety, meeting European EN 50575 CPR Class B2ca and NFPA 90A requirements in occupied spaces
- Lime color-coding per TIA-598-D standard simplifies OM5 fiber identification during MACs (Moves, Adds, Changes) and prevents accidental cross-connection with OM3 (aqua) or OM4 (erika violet) infrastructure
High-speed datacenter fabrics built on 100 Gigabit and 400 Gigabit Ethernet demand fiber infrastructure capable of supporting shortwave wavelength division multiplexing without the attenuation penalties and modal bandwidth limitations that throttle legacy OM3 multimode links. The FWUYL7575LNM017 delivers 3,500 MHz·km effective modal bandwidth at 850nm and extends SWDM reach to 150 meters—sufficient for spine-to-leaf connections in pod-based architectures where centralized core switches feed multiple rows of top-of-rack aggregation layers. Unlike single-fiber duplex patch cords that require 12 or 24 discrete cable pulls for a single 100G QSFP28 or 400G QSFP-DD transceiver breakout, this trunk assembly consolidates all 24 fibers into one jacket with integrated strain relief and bend-radius protection, reducing installation labor by 70 percent and eliminating the cable management nightmare of loose bundling with velcro wraps. Factory polishing ensures endface geometry meets IEC 61300-3-35 specifications for radius of curvature, apex offset, and fiber height—critical parameters that field techs struggle to replicate consistently with hand-polish kits, especially under deadline pressure during cutovers. Each connector pair ships with insertion loss documentation traceable to NIST-certified reference test jumpers, giving you baseline performance metrics before the cable ever leaves the factory floor.
The small-diameter trunk construction addresses the single biggest constraint in retrofit datacenter expansions: pathway fill capacity. Traditional 24-fiber OM3 trunk assemblies with 3.0mm tight-buffered subunits produce an overall diameter near 18mm, consuming 254mm² of conduit cross-section per TIA-569-E fill-ratio calculations. The FWUYL7575LNM017 reduces that footprint to approximately 155mm²—a 39 percent space savings that translates directly into more fiber strands per cable tray or the ability to route power whips and copper management links alongside fiber without exceeding NEC Article 300.17 conduit fill limits. For hot-aisle containment deployments where under-floor cable trays also carry chilled-water return lines and must preserve minimum airflow velocity, this reduction in cable bulk prevents the static pressure drops that force CRAC units into high-fan alarm states. The 17-meter length is purpose-sized for the 15 to 16-meter diagonal span between an end-of-row network cabinet and a mid-room core switch when accounting for vertical risers, horizontal service loops, and the 10x minimum bend radius safety margin required by TIA-568-C.3 Annex A (10 times the cable outer diameter, or roughly 180mm for this assembly). Installations that splice shorter pre-terminated jumpers using fusion trays introduce 0.1 to 0.3 dB of additional loss per splice point and create failure domains at every enclosure—losses and risk points eliminated entirely by specifying the correct single-run length from the factory.
LSZH jacketing is non-negotiable for datacenters operating under NFPA 75 (electronic equipment protection) or serving tenants in jurisdictions enforcing EN 50575 Construction Products Regulation (CPR). When exposed to flame, PVC-jacketed cable releases hydrochloric acid vapor and dense black smoke that corrodes server hardware, obscures egress lighting, and triggers life-safety failures even in sprinklered spaces. The FWUYL7575LNM017's halogen-free compound limits smoke emission to less than 60 percent light transmittance per IEC 61034-2 testing and produces zero corrosive acidic gases, protecting both personnel during evacuation and installed IT assets from chemical damage. This assembly meets TIA-492-AAAD multimode fiber specifications and IEC 60793-2-10 Type A1a.3 geometry requirements, ensuring compatibility with Cisco, Juniper, Arista, and Mellanox 100G/400G optics across mixed-vendor environments, and carries RoHS compliance for installations serving EU-based cloud tenants with extended producer responsibility mandates. Panduit backs QuickNet assemblies with a comprehensive manufacturer warranty covering fiber attenuation, connector endface damage, and jacket integrity—critical coverage when a single failed trunk can take an entire leaf switch offline and cascade into application-layer timeouts across dependent virtualization clusters.
