Panduit FWUYL7575LAM005 QuickNet™ 24-Fiber OM5 LSZH Trunk Cable Assembly
The Panduit FWUYL7575LAM005 is a factory-terminated 24-fiber OM5 wideband multimode trunk cable assembly designed for high-density datacenter and enterprise network deployments. OM5 fiber supports 40GBASE-SR4 and 100GBASE-SR4 transmission to 150 meters—50% farther than OM4—and enables shortwave wavelength division multiplexing (SWDM) for 40G/100G over duplex connectivity, reducing fiber pair requirements by 75%. The 5-meter (16.4 ft) length suits spine-to-leaf interconnects, horizontal trunk runs, and patch panel consolidation points. LSZH (low smoke zero halogen) jacketing meets NFPA 90A plenum requirements and international building codes for air-handling spaces, critical in occupied datacenters and equipment rooms. Lime jacket color conforms to TIA-598-D identification standards for OM5 fiber. QuickNet pre-termination eliminates field fusion splicing, cutting installation time by 60-80% on time-sensitive cutovers and reducing deployment cost in labor-constrained markets.

- TIA-568-C.3 / ISO/IEC 11801 Compliant: Meets or exceeds insertion loss (≤0.75 dB typical), return loss (≥-20 dB), and polarity standards for structured cabling systems
OM5 Wideband Multimode Technology: OM5 fiber extends the multimode roadmap by supporting shortwave wavelength division multiplexing (SWDM) across 850 nm, 880 nm, 910 nm, and 940 nm transmission windows. This enables 40GBASE-SR BiDi and 100GBASE-SR BiDi optics to deliver 40G or 100G over a single duplex LC connection instead of 8-fiber or 4-fiber MPO parallel optics, cutting transceiver port count and fiber pair requirements by 75%. Effective modal bandwidth (EMBc) of 4700 MHz·km at 850 nm—measured via overfilled launch per TIA-492-AAAD—supports 40GBASE-SR4 and 100GBASE-SR4 to 150 meters, a 50% reach extension over OM4's 100-meter limit. This additional 50 meters covers 95% of horizontal datacenter runs without moving to singlemode infrastructure, deferring the cost and complexity of SM optics, tight bend-radius management, and APC connector polishing. OM5 fiber is backward-compatible with OM3 and OM4 VCSEL optics at 850 nm; existing 10GBASE-SR and 40GBASE-SR4 transceivers operate over OM5 plant at the same or extended reach. The 50-micron core diameter maintains compatibility with installed OM3/OM4 patch cords and adapters, allowing phased migration without forklift upgrades to passive infrastructure. As 200G and 400G BiDi optics enter volume production in 2026-2027, OM5 infrastructure supports these speeds over the same duplex fiber pairs, future-proofing the plant for 5-7 year technology refresh cycles without rip-and-replace cabling work.
QuickNet Pre-Terminated Trunk Assembly Construction: The FWUYL7575LAM005 ships with factory-installed connectors on both ends, pre-tested for insertion loss (IL), return loss (RL), and polarity per TIA-604-5 (FOCIS-5) inspection standards. Factory termination eliminates the need for fusion splicing equipment rental ($800-1,200/day), certified fusion technician labor ($85-140/hour), and field test time (15-20 minutes per 12-fiber trunk), reducing total installation cost by 50-65% on typical 40-trunk datacenter builds. Each trunk is serialized with IL/RL test data; end-to-end channel insertion loss is ≤0.75 dB typical for the 5-meter length, well below the 1.5 dB TIA-568-C.3 channel budget for 10-meter permanent links. Polarity is maintained via keyed MTP connectors (Type A, Type B, or Type C per TIA-568 Annex D); installers select polarity type at order time to match patch panel and switch port layouts, preventing field re-pinning or adapter-based polarity correction that adds 0.3-0.5 dB insertion loss per mated pair. Reduced-diameter cable construction—30-40% smaller outer diameter than legacy trunk designs—uses tight-buffered 900-micron subunits in a flexible round jacket, improving bend performance (10× cable OD minimum bend radius vs. 20× for rigid distribution cables) and maximizing usable fill ratio in 4-inch ladder rack and 2-inch conduit. On high-density builds with 60+ trunk cables per pathway, this diameter reduction prevents exceeding NEC Article 300.17 conduit fill limits (40% for 3+ conductors) and eliminates the need to upsize from 4-inch to 6-inch cable tray mid-project, which delays schedules by 2-4 weeks for material procurement and re-engineering.
LSZH Jacket for Safety-Critical and International Deployments: The LSZH (low smoke zero halogen) jacket is formulated from halogen-free polymers that produce <0.5% hydrogen chloride and hydrogen fluoride by mass when burned, compared to 15-30% halogen content in PVC jacketed cables. During a fire event, LSZH cables emit 60-80% less smoke opacity (measured per ASTM E662) and produce non-corrosive combustion byproducts, reducing toxicity risk to occupants during evacuation and minimizing damage to adjacent IT equipment from acidic smoke residue. LSZH jacketing is required by NFPA 90A for cables installed in air-handling spaces (plenums, raised floors, drop ceilings) where PVC combustion gases would distribute through HVAC systems to occupied zones. International building codes—including IEC 60332-3 Category C (bundle flame propagation) and IEC 61034 (smoke density)—mandate LSZH for installations in the EU, UK, Middle East, and Asia-Pacific markets; PVC-jacketed cables are prohibited in these jurisdictions for above-ceiling and riser applications. LSZH construction is also specified in LEED v4.1 and WELL Building Standard credit paths for low-emitting materials (EQ Credit 9), where halogen-free cables contribute to Indoor Air Quality points and reduce long-term off-gassing of plasticizers and flame retardants in occupied IT spaces. On projects requiring simultaneous UL/FM and IEC compliance—common in multinational datacenter rollouts or build-to-suit colocation facilities—LSZH trunk cables eliminate the need to stock parallel PVC (North America) and LSZH (international) inventory, reducing SKU count and simplifying vendor qualification.
High-Density Datacenter and Enterprise Deployment Scenarios: The 24-fiber trunk consolidates connectivity for six duplex 40G links, six duplex 100G SWDM links, twelve duplex 10G links, or twenty-four simplex monitoring/management ports in a single cable assembly, reducing bundle count in vertical risers and horizontal cable trays by 85-90% compared to individual duplex patch cords. Typical applications include spine-to-leaf aggregation layer trunks (5-15 meter lengths between end-of-row switches and middle-of-row spines), patch panel zone consolidation (connecting equipment room panels to intermediate distribution frames on different floors), and storage area network (SAN) trunk links between compute racks and centralized storage arrays. In modular datacenter builds and prefabricated IT pods, QuickNet trunks are pre-installed in cable trays during off-site factory integration, then commissioned on-site with simple MTP mating at patch panels and switch MPO ports, cutting field installation time from 6-8 hours per rack to under 90 minutes. The 5-meter (16.4 ft) length covers 80% of top-of-rack to aggregation switch distances in standard 42U and 48U rack layouts with 1.2-1.5 meter aisle widths; horizontal cable management arms and vertical managers consume 1.5-2 meters of slack, leaving 3-3.5 meters for the physical run. For longer distances (7-15 meters), Panduit offers the same assembly in 10m, 15m, 20m, and 30m lengths; for shorter patch panel jumpers (1-3 meters), 1m, 2m, and 3m variants are available. Lime jacket color per TIA-598-D OM5 identification standard allows instant visual differentiation from aqua OM3 and erika violet OM4 trunks during adds/moves/changes, preventing accidental cross-connection of OM5 SWDM optics to OM3 plant (which would cause link flap or failure to train at 40G/100G due to insufficient modal bandwidth).
The Panduit FWUYL7575LAM005 trunk assembly is covered by Panduit's 25-year QuickNet system warranty when installed as part of a complete Panduit structured cabling system (cable, connectors, patch panels, and patch cords from the same manufacturer). This end-to-end warranty covers channel performance to TIA-568-C.3 specifications and includes applications support for 40G/100G optics qualification and troubleshooting, eliminating finger-pointing between cable, connector, and transceiver vendors during post-deployment link failures. OM5 wideband multimode future-proofs the infrastructure for 200GBASE-SR4 and 400GBASE-SR8 optics expected in 2027-2028 product cycles, extending the usable life of the physical plant to 10-12 years without re-cabling, compared to 5-7 year lifecycles for OM3 installations facing bandwidth exhaustion. Factory termination and LSZH construction reduce total project cost by 40-50% on fast-track builds where labor availability, permitting timelines, and safety compliance drive schedule risk, making QuickNet trunks the standard solution for hyperscale datacenter operators, colocation providers, and enterprise IT teams executing infrastructure refreshes under constrained budgets and fixed cutover windows.
