Panduit FWUYL7575LNM031 QuickNet OM5 24-Fiber Trunk Cable Assembly
The Panduit FWUYL7575LNM031 is a 24-fiber OM5 trunk cable assembly engineered for high-density data center deployments where pathway congestion, deployment speed, and future bandwidth headroom are critical concerns. This 31-meter (101.71 ft) pre-terminated trunk delivers extended reach for cross-row spine connections, inter-rack distribution, or zone cabling architectures while consuming 30 to 40 percent less tray and conduit space than legacy trunk assemblies. The lime LSZH jacket provides low-smoke, zero-halogen protection for enclosed equipment rooms and meets international flammability standards. QuickNet pre-terminated connectors eliminate field fusion splicing, reducing installation time from hours to minutes and removing the skill-and-equipment barrier that traditionally accompanies high-fiber-count backbone cabling.
Key Features
- OM5 wideband multimode fiber — 50 μm core supports 40/100 Gb/s to 150 meters and 100 Gb/s SWDM to 440 meters, providing runway for 200G/400G upgrades without re-cabling
- 24-fiber count — backbone/spine capacity for leaf-spine fabrics, storage-area networks, or high-port-density switch uplinks
- Small-diameter construction — 30 to 40% reduction in cross-sectional area compared to conventional trunk assemblies; critical advantage in congested vertical cable managers, overhead ladder rack, and under-raised-floor pathways
- 31-meter engineered length — spans typical data center cross-row distances (80-100 ft) without mid-span splices or excessive service loops
- Lime LSZH jacket — low smoke, zero halogen flammability rating for equipment rooms, telecommunications spaces, and air-handling plenums; lime color provides instant visual identification in multi-cable environments
- Pre-terminated QuickNet connectors — factory-terminated and tested assemblies arrive ready to plug in; eliminates fusion splicer rental, technician certification requirements, and the 15-30 minute per-splice labor burden
- TIA-568-C.3 and ISO/IEC 11801 compliant — meets North American and international structured cabling standards for insertion loss, return loss, and polarity
- Single-unit packaging — individually packaged trunk assembly ships ready for immediate deployment without bulk carton unpacking or job-site inventory management
OM5 wideband multimode fiber is optimized for short-wave division multiplexing (SWDM) across the 850 nm to 950 nm window, enabling four or more wavelengths to share a single fiber pair. This architecture doubles or quadruples effective per-fiber bandwidth compared to OM3/OM4 systems limited to 850 nm, making OM5 the preferred choice for data centers planning 200 Gb/s or 400 Gb/s migration paths within existing 24-fiber trunks. The 50 μm core diameter maintains compatibility with legacy OM3/OM4 transceivers while future-proofing the physical layer for next-generation optics. Panduit's small-diameter trunk construction reduces the overall cable bundle diameter by shrinking buffer tube wall thickness, tightening fiber lay, and using a thinner LSZH outer jacket without compromising bend-radius performance or mechanical protection. The result: a 24-fiber trunk that occupies the pathway space of a traditional 12-fiber assembly. In practice, this means you can route four trunks through a 4-inch vertical manager that previously held two, or thread a new trunk alongside existing copper and fiber bundles in a live production aisle without ripping out cable tray covers or disrupting airflow containment. The pre-terminated QuickNet connectors eliminate the single largest time-and-cost variable in high-fiber-count deployments—field termination. A fusion splicer, cleaver, and certified technician can cost $3,000-$5,000 per day; each 24-fiber trunk requires 24 individual splices at 15-30 minutes each under best-case conditions, and any contamination, misalignment, or environmental vibration forces a re-splice. Factory pre-termination moves that quality-control process into a controlled manufacturing environment with automated inspection, then delivers a plug-and-play assembly that installs in under 10 minutes: pull the trunk, dress the legs, plug the connectors, verify link light, done. For disaster-recovery scenarios, modular data center builds, or rapid capacity adds during a maintenance window, that time savings is the difference between meeting and missing a cutover deadline.
Data center spine-leaf architectures typically deploy 24-fiber trunks as the physical backbone between aggregation switches (spines) and top-of-rack or end-of-row distribution switches (leaves). Each 24-fiber trunk supports twelve duplex links, allowing a single cable pull to serve six 40G QSFP+ uplinks, twelve 10G SFP+ uplinks, or a mix of speeds as the fabric evolves. The 31-meter engineered length of the FWUYL7575LNM031 is purpose-built for cross-row or cross-aisle runs in typical enterprise and colocation facilities—long enough to span 80-100 linear feet with slack for vertical risers and service loops, short enough to avoid the excessive coiling and zip-tie bundles that plague over-length assemblies. In hot-aisle/cold-aisle containment designs, cable bulk directly impacts airflow: every unnecessary inch of cable diameter restricts the effective free area in overhead or underfloor pathways, forcing CRAC units to work harder and raising PUE. The 30-40% diameter reduction of Panduit's small-diameter trunk construction translates to measurably better airflow in constrained pathways. The lime LSZH jacket provides three installer advantages: first, LSZH (low smoke, zero halogen) construction is required or strongly preferred in enclosed equipment rooms, telecommunications closets, and air-handling spaces where PVC combustion byproducts—hydrochloric acid and dense black smoke—pose life-safety and equipment-damage risks during a fire event. Second, lime color-coding allows instant visual identification when troubleshooting or tracing circuits in a multi-vendor, multi-generation cable plant; you can distinguish OM5 trunks from aqua OM3, OM4, or legacy OM1/OM2 fibers at a glance. Third, the LSZH jacket is more flexible and easier to dress than PVC or OFNP-rated assemblies, reducing the pulling tension and bend-radius stress during installation—critical when threading a pre-terminated trunk through a crowded vertical manager or around a 90-degree corner in a ladder rack.
The FWUYL7575LNM031 meets TIA/EIA-568-C.3 (commercial building telecommunications cabling standard for optical fiber), ISO/IEC 11801 (international generic cabling standard), TIA-604-5 (FOCIS-5 fiber optic connector intermateability standard), TIA-492-AAAD (OM5 fiber performance specification), and IEC 60793-2-10 type A1a.3 (multimode fiber detail specification). It is RoHS-compliant for lead-free, low-toxicity materials. These certifications ensure interoperability with standards-compliant patch panels, cassettes, enclosures, and transceivers from any vendor—critical when integrating Panduit structured cabling with Cisco, Arista, Juniper, or Dell switching infrastructure. Panduit's QuickNet ecosystem includes color-matched cassettes, pre-loaded panels, and MTP/MPO-to-duplex LC breakout modules that share the same factory-termination quality and testing rigor as this trunk assembly, allowing you to design and deploy an end-to-end fiber backbone with a single-source Bill of Materials and unified warranty coverage. For data center managers and infrastructure integrators facing pathway congestion, aggressive deployment timelines, or 100G-and-beyond bandwidth planning, this trunk assembly delivers a concrete, measurable advantage: you get more fiber capacity into the same physical space, you eliminate the field-termination bottleneck that turns a two-hour cable pull into a two-day splice marathon, and you future-proof the physical layer for SWDM optics that will double or quadruple your per-fiber throughput without pulling new cable. That combination—space efficiency, installation speed, and bandwidth headroom—is exactly what makes the difference between a smooth data center expansion and a pathway-redesign crisis six months later when you realize you're out of tray space and out of service-window time.
