Panduit FWUYL7575LAM085 QuickNet™ OM5 24-Fiber Trunk Assembly
The Panduit FWUYL7575LAM085 is an 85-meter OM5 fiber trunk cable assembly engineered for high-density data center backbone deployments requiring extended reach and future-proof bandwidth. This 24-fiber trunk uses Panduit's HD Flex cable construction to deliver 30-40% space savings over standard trunk assemblies, critical when conduit fill and pathway congestion limit expansion. OM5 wideband multimode fiber supports 100GBASE-SR4, 100G SWDM4, and emerging 400G/800G short-reach applications over distances that legacy OM3/OM4 cannot sustain. Method B polarity and Ultra Insertion Loss performance grade ensure plug-and-play compatibility with TIA-568 structured cabling standards while minimizing link budget penalties on long horizontal or backbone runs.

OM5 fiber represents the most significant advancement in multimode technology since OM4. Unlike OM3/OM4, which optimize for 850nm laser transmission, OM5 is engineered as a wideband multimode fiber supporting four distinct wavelengths (850nm, 880nm, 910nm, 940nm) simultaneously. This enables Short Wavelength Division Multiplexing (SWDM) technology, where a single 100G transceiver transmits four 25G channels over a single duplex fiber pair instead of requiring eight fibers with parallel optics. For 24-fiber trunks like the FWUYL7575LAM085, this means each trunk can support twelve 100G SWDM links instead of three 100GBASE-SR4 links, effectively quadrupling port density. The 50-micron core maintains OM4-class modal bandwidth (4700 MHz·km at 850nm) while adding <2.0 dB/km differential mode delay across all four SWDM wavelengths. Panduit's Ultra Insertion Loss specification tightens connector attenuation to <0.35 dB typical, compared to industry-standard <0.75 dB maximum, which translates to 1.6 dB saved across a four-connector channel—enough to extend 100GBASE-SR4 reach from 70m to 100m or enable 400GBASE-SR8 over 100m when used with OM5-optimized transceivers. The PanMPO connector is Panduit's ruggedized implementation of the MPO/MTP interface, featuring a stainless steel guide pin retention clip and glass-reinforced thermoplastic housing rated for 1,500 mating cycles (5× industry standard). Method B polarity uses a key-up to key-down orientation with straight-through fiber mapping (fiber 1 to fiber 1, fiber 12 to fiber 12), which allows direct connection between two transceivers without adapter keypins or polarity-reversing crossover modules. This is the TIA-568-C.0 Annex E recommended method for 40G/100G structured cabling, as it eliminates field guesswork and supports both parallel-optics (MPO-to-MPO) and breakout (MPO-to-LC duplex) architectures with standard adapter panels.
The HD Flex cable construction uses a tight-buffered central tube design with 900-micron individual fiber coating and a 4.7mm outer diameter—approximately 35% smaller than legacy 24-fiber distribution cables. This diameter reduction delivers three compounding benefits for data center installations. First, conduit fill ratio improves dramatically: a standard 1-inch innerduct rated for 40% fill can accommodate four HD Flex 24F trunks instead of three standard trunks, increasing fiber count from 72 to 96 without pathway modifications. Second, smaller cable diameter improves airflow in overhead cable trays and under-floor pathways, reducing hot-spot formation in high-density pod architectures where dozens of trunks converge at end-of-row aggregation points. Third, reduced cable stiffness (minimum bend radius of 10× cable diameter during installation, 5× at rest) allows tighter routing around structural obstacles and into high-density MPO cassette panels without mechanical stress that degrades IL over time. The LSZH jacket is a zero-halogen thermoplastic compound that produces <0.5% HCl gas and <50% light transmission obscuration when burned, meeting IEC 60332-1 (flame propagation) and IEC 61034 (smoke density) requirements for European EN 50173 and international ISO/IEC 11801 installations. Unlike PVC jackets, which release hydrochloric acid during combustion, LSZH compounds are specified for occupied spaces, plenum returns, transportation tunnels, and any environment where smoke toxicity and corrosion during fire represent life-safety or asset-damage risks. The 85-meter length is purpose-built for horizontal backbone applications: it spans the typical 70-80 meter distance between main distribution area (MDA) and intermediate distribution area (IDA) in a large campus building while leaving 5-10 meters for vertical riser slack, patch panel dressing, and future re-termination. For multi-building data center campuses, 85m supports direct building-to-building links up to 250 feet apart without active equipment, eliminating the cost and failure points of media converters or outdoor fiber enclosures. The integrated pulling eye is a reinforced Kevlar strength member loop pre-installed on one connector boot, rated for 100N (22 lbf) pulling tension. This allows installers to attach standard fish tape or pull cord without field-adding cable grips or strain relief, cutting installation time by 15-20 minutes per trunk and preventing jacket damage from improvised pulling methods. On vertical riser pulls, the pulling eye supports the cable's weight during installation, then remains in place as a permanent strain relief once the cable is dressed into the patch panel.
The FWUYL7575LAM085 ships with factory test reports documenting IL and return loss for all 24 fibers per TIA-568-C.3 Tier 2 certification requirements, which streamlines project acceptance testing and provides a baseline for future troubleshooting. Compliance with TIA-492-AAAD (OM5 fiber specification) and IEC 60793-2-10 Type A1a.3 ensures interoperability with OM5 transceivers from Cisco, Arista, Juniper, and other IEEE 802.3 standards-compliant vendors. RoHS compliance per EU Directive 2011/65/EU confirms the absence of lead, cadmium, mercury, and hexavalent chromium, meeting procurement requirements for government, healthcare, and multinational enterprise installations. For integrators managing spine-leaf architectures, this trunk eliminates the labor and failure risk of field termination: a 24-fiber trunk with 48 discrete connector endpoints would require 8-12 hours of field termination and testing, compared to <30 minutes for rack-and-plug deployment of a factory-terminated assembly—a labor savings exceeding $800 per trunk at prevailing installation rates, which offsets the premium cost of pre-terminated infrastructure within a single deployment cycle.
