Panduit FWUYL7575LAM078 OM5 24-Fiber QuickNet Trunk Cable Assembly
The Panduit FWUYL7575LAM078 is a 78-meter OM5 trunk cable assembly engineered for high-density data center interconnects requiring extended reach and rapid deployment. This 24-fiber LSZH trunk features PanMPO female connectors on both ends with Method B polarity, HD Flex transition design for tight-radius routing, and ultra insertion loss performance. The lime-jacketed cable includes a pulling eye on one end to simplify installation through congested pathways, and its small-diameter construction reduces pathway fill by 30-40% compared to traditional trunk designs—critical when every square inch of conduit and cable tray counts in hyperscale or colocation environments.
Key Features
- OM5 Fiber Technology: 50-micron multimode fiber optimized for short-wave wavelength division multiplexing (SWDM), supporting four independent 28 Gbps channels per fiber pair for 100G/200G/400G applications over extended distances
- 24-Fiber High-Density Trunk: Consolidates two 12-fiber ribbons into a single pull, reducing installation labor and pathway congestion while maintaining full duplex capacity for twelve 100G links or six 400G links
- PanMPO Female-to-Female Connectivity: Panduit's precision-aligned MPO connectors with Method B polarity (key-up to key-down) ensure correct fiber mapping for duplex transceivers without field polarity conversion—plug into standards-compliant breakout modules or switch faceplates and light up immediately
- Ultra Insertion Loss Specification: Factory-terminated and tested to deliver insertion loss well below 0.35 dB per mated connection pair, preserving link budget for 100m+ OM5 channels and ensuring margin for future transceiver generations
- HD Flex Construction: Reduced-diameter cable jacket and optimized fiber buffering allow bend radius down to 30mm during installation and 15mm static, enabling tight turns around vertical cable managers, through crowded horizontal pathways, and into high-density patch panels without kinking or signal degradation
- Low Smoke Zero Halogen (LSZH) Jacket: IEC 60332-3-24 flame-rated LSZH formulation produces minimal smoke and no corrosive halogen gases during combustion—required for enclosed raised-floor data centers, European installations, and any environment where personnel egress or equipment protection during fire is a design priority
- Integrated Pulling Eye: Stainless steel pulling eye factory-installed on one trunk end distributes tensile load across the entire cable assembly during long pulls, preventing connector damage and fiber stress that can degrade performance post-installation
- Lime Jacket Color: High-visibility lime green identifies OM5 fiber at a glance per TIA-598-D color code, preventing cross-connection errors when OM3, OM4, and OM5 infrastructures coexist in the same rack or zone
- QuickNet Pre-Terminated System: Part of Panduit's QuickNet product family, designed for zero on-site termination—unpack, route, plug in, test, and commission in a fraction of the time required for field-terminated solutions, with factory-grade performance on every link
OM5 fiber represents the current state-of-the-art in multimode data center cabling, extending the economic reach of multimode optics to 150 meters at 100 Gbps (using SWDM transceivers) and 100 meters at 400 Gbps. Unlike OM3 and OM4, which rely on a single 850nm wavelength, OM5 supports four discrete wavelengths (850nm, 880nm, 910nm, 940nm) multiplexed onto each fiber pair, effectively quadrupling bandwidth without adding fiber count. This FWUYL7575LAM078 assembly's 24-fiber configuration provides twelve duplex channels—enough for a full top-of-rack switch uplink bundle, a storage array controller interconnect, or a spine-leaf tier connection—while the 78-meter length handles typical intra-building runs between main distribution areas (MDAs) and intermediate distribution areas (IDAs), or floor-to-floor vertical riser applications in mid-rise facilities. The PanMPO female terminations mate directly with Panduit's cassette modules, breakout panels, and MPO-to-duplex LC adapter plates, allowing you to transition from 24-fiber trunk to individual duplex patch cords exactly where you need them. Method B polarity (also called "straight-through with key flip") is the dominant standard for duplex transceiver compatibility: transmit fibers on one end align to receive fibers on the far end without crossover adapters or custom pinouts, reducing deployment complexity and eliminating a common source of no-light trouble tickets during turn-up.
Installation efficiency is a primary design goal for this trunk. The integrated pulling eye distributes tensile load across the cable's strength members rather than concentrating stress at the connector boot—essential when threading 78 meters through multiple j-hooks, around vertical corners, or across long horizontal cable trays where friction and weight combine to generate hundreds of pounds of pull force. The HD Flex construction allows the cable to negotiate tight turns without exceeding minimum bend radius, a common failure mode when installers force standard-diameter trunks through crowded pathways or into high-density panels with <2U vertical space. Reduced outer diameter also translates directly to lower pathway fill: a 24-fiber HD Flex trunk occupies roughly the same cross-sectional area as a legacy 12-fiber standard trunk, effectively doubling your usable pathway capacity or allowing you to defer costly conduit and tray expansion projects. LSZH jacketing is non-negotiable in many jurisdictions and facility types—European building codes, pharmaceutical clean rooms, telecom central offices, and raised-floor data centers with underfloor air plenums all restrict PVC and other halogenated materials due to toxic smoke and corrosive byproducts that damage electronics and endanger occupants during fire events. This cable's IEC 60332-3-24 rating certifies it meets the strictest vertical flame-spread requirements, while the halogen-free formulation ensures compliance with RoHS and REACH environmental directives.
The FWUYL7575LAM078 ships with full test reports documenting insertion loss and return loss for every fiber position, traceable to NIST-calibrated reference standards. It meets or exceeds TIA-568-C.3 performance requirements for OM5 permanent links, ISO/IEC 11801 generic cabling specifications, and TIA-604-5 (FOCIS-5) mechanical interface standards for MPO connectors. This level of manufacturing rigor eliminates the variability inherent in field terminations—no risk of contaminated endfaces, misaligned ferrules, or over-polished cores—and provides a known-good foundation for 25G/50G/100G/200G/400G optics. For integrators managing multi-building campus networks, hyperscale data center builds, or modular data center deployments where speed and repeatability determine project success, factory-terminated OM5 trunks like this one convert fiber installation from a skilled trade into a plug-and-play commodity, compressing schedules and reducing the specialized labor pool required on site.
