Panduit FWUYL7575LAM048 OM5 24-Fiber LSZH Trunk Cable - 48m

Panduit FWUYL7575LAM048 OM5 24-Fiber QuickNet Trunk Cable Assembly

The Panduit FWUYL7575LAM048 is a 48-meter OM5 trunk cable assembly engineered for high-density data center deployments requiring extended reach and future-proof bandwidth capacity. This 24-fiber trunk features PanMPO Female connectors on both ends with Method B polarity, Ultra Insertion Loss performance grading, and Low Smoke Zero Halogen (LSZH) jacketing for installations subject to European EN or International IEC fire safety codes. Part of Panduit's QuickNet portfolio, this trunk delivers the small-diameter HD Flex construction that reduces pathway fill by 30-40% compared to legacy bundled-duplex approaches, while the factory-terminated design eliminates field splicing labor and the quality variability that comes with on-site termination. The integrated pulling eye on one end simplifies installation through conduit or overhead cable tray. Ideal for 100GBASE-SR4, 400GBASE-SR8, or future 800G short-reach optics in enterprise data centers, colocation facilities, or hyperscale compute environments where OM5's short-wave wavelength division multiplexing (SWDM) capability provides a four-fold increase in effective bandwidth over the same fiber count.

Key Features

• OM5 Wideband Multimode Fiber: 50µm core supports SWDM transmission—four wavelengths over a single fiber pair—enabling 400GBASE-SR4.2 on just eight fibers (versus 16 fibers on OM4) and positioning the infrastructure for 800G migrations without rip-and-replace
• 24-Fiber High-Density Trunk: Single-cable assembly replaces twelve duplex patch cords, cutting port-to-port connection time from hours to minutes and drastically reducing cable congestion at switch faceplates and patch panels
• PanMPO Female to PanMPO Female Connectors: Panduit's precision-aligned MPO variant with proprietary keying maintains physical-contact geometry across hundreds of mate cycles; Method B polarity (key-up to key-down) maps directly to duplex LC modules without adapter flipping or crossover trunks
• Ultra Insertion Loss Grade: Maximum 0.35 dB per mated connector pair tested at 850nm—tighter than TIA's 0.75 dB Generic standard—preserves link budget for multi-tier spine-leaf fabrics or daisy-chained storage-area networks where every tenth of a dB counts
• LSZH Jacket Construction: IEC 60332-1/-3 flame-propagation rating and minimal halogen content meet European CPR Euroclass requirements for vertical shafts, plenum spaces, and equipment rooms where PVC off-gassing during fire poses evacuation or equipment risk
• HD Flex Small-Diameter Design: 8.4mm overall cable diameter (typical for 24-fiber HD trunk) versus 14mm+ for standard 24-fiber round constructions, yielding 40% cross-sectional area savings—critical when ladder rack or overhead tray is at 50% fill and you're adding another switch row
• 48-Meter Extended Reach: 157-foot length spans end-of-row to middle-of-row switch positions in large data halls or connects across adjacent hot-aisle/cold-aisle pods without mid-span splice enclosures, reducing labor and failure points
• Factory-Terminated & Factory-Tested: Each fiber insertion loss and return loss tested per TIA-568-C.3 Tier 2 requirements; serialized test report included—eliminates the 2-4 hour per-trunk field fusion-splicing cycle and the risk of contamination or geometry errors from field work
• Integrated Pulling Eye: Preinstalled stainless pulling eye on one connector end distributes tensile load across the aramid strength member, not the fiber cores, during conduit pulls—supports up to 100 lbs pulling tension without risking microbend attenuation spikes
• Lime Cable Jacket: High-visibility lime green identifies OM5 cabling per TIA-598-D color code, preventing accidental cross-patching with OM3 (aqua) or OM4 (Erika violet) infrastructure during moves/adds/changes and simplifying day-two troubleshooting

OM5 wideband multimode fiber represents the current endpoint in the 50µm multimode roadmap, extending the VCSEL-based (vertical-cavity surface-emitting laser) transceiver ecosystem that has dominated data center interconnects since 10GBASE-SR. Where OM3 and OM4 were optimized for single-wavelength 850nm transmission, OM5 adds the effective modal bandwidth (EMBc) specification across four distinct SWDM wavelengths—850nm, 880nm, 910nm, and 940nm—each carrying an independent data stream. This wavelength division multiplexing approach allows a single fiber pair to transport 100 Gb/s (4× 25G lanes), 200 Gb/s (4× 50G lanes), or 400 Gb/s (4× 100G lanes) without requiring parallel optics' 8-fiber or 20-fiber ribbons. For a 400GBASE-SR4.2 link, you need only eight fibers total (four transmit, four receive) instead of the 16 fibers required by 400GBASE-SR16 on OM4. The practical impact: a single 24-fiber OM5 trunk like the FWUYL7575LAM048 supports three full 400G links with breakout modules—or twelve 100G SR4 links—within the same cable that previously handled six 40G links. The Ultra Insertion Loss grade further tightens the performance window, guaranteeing maximum 0.35 dB loss per mated connector pair versus the 0.75 dB allowed under TIA-568-C.3's generic tier. That 0.40 dB margin matters in multi-hop topologies—spine-to-leaf-to-server or primary-to-secondary-to-tertiary storage—where cumulative connector loss can push marginal transceivers past their receiver sensitivity threshold, causing intermittent bit errors or link flaps that are maddeningly difficult to isolate in production. Panduit's factory testing of every fiber (not just sample testing) ensures you're not gambling on whether fibers 13-24 will meet spec when you light them up six months post-install.

Data center trunk cable deployments fall into two common scenarios: top-of-rack to end-of-row aggregation switches (typically 20-40 meters), and cross-aisle or cross-pod links between distribution switches (30-60 meters). The FWUYL7575LAM048's 48-meter length addresses the latter—connecting switch stacks separated by three or four racks of servers, spanning from a hot-aisle enclosure to a cold-aisle network cabinet, or linking edge-of-facility telecom rooms to mid-facility compute rows without requiring intermediate patch panels or splice enclosures that add insertion loss, labor cost, and failure points. The HD Flex construction's reduced diameter becomes decisive in these longer runs: a bundle of six 24-fiber HD trunks occupies roughly the same cable tray cross-section as three legacy round trunks, allowing you to double fabric bandwidth (from 1.6 Tbps to 3.2 Tbps across six trunks at 400G per trunk) without expanding pathway infrastructure or violating the NEC's 50% conduit fill ratio. Method B polarity—where the key-up connector (position 1-12) at one end maps to the key-down connector (position 13-24) at the far end—is the TIA-568 standard for duplex-to-MPO breakout applications. It means you can plug this trunk into a standard MPO-to-LC breakout cassette (or a 400G-to-4×100G QSFP breakout module) without needing Type-C crossover pinouts or field adapter flipping—critical when you're deploying 50 trunks in a maintenance window and can't afford polarity debugging. The LSZH jacket, while mandatory in Europe under Construction Products Regulation (CPR) Euroclass Cca or B2ca ratings, is increasingly specified in North American data centers subject to local amendments of NFPA 70 (National Electrical Code) or facilities where underwriters require low-smoke materials in return-air plenums, vertical shafts, or rooms with insufficient egress paths. The material substitution has negligible impact on flexibility or bend radius compared to PVC riser-rated (CMR) or plenum-rated (CMP) jackets, but it dramatically reduces hydrogen chloride and opacity during combustion—buying critical seconds for evacuation and reducing corrosive-gas damage to adjacent IT equipment in a fire scenario.

This trunk assembly ships with full TIA-568-C.3 Tier 2 insertion loss and return loss test results for every fiber, traceable by serial number—documentation that satisfies customer acceptance testing requirements and provides baseline performance data for future troubleshooting. Compliant with ISO/IEC 11801 (international structured cabling), TIA/EIA-568-C.1 and -C.3 (North American cabling standards), TIA-604-5/FOCIS-5 (MPO connector geometry), TIA-492-AAAD (OM5 fiber performance), IEC 60793-2-10 Type A1a.3 (multimode fiber categories), and RoHS (lead-free, halogen-reduced materials), the FWUYL7575LAM048 meets procurement checkbox requirements for federal, healthcare, education, and hyperscale operators. The QuickNet sub-brand designates Panduit's pre-terminated, rapid-deployment fiber portfolio—trunk cables, breakout cassettes, and transition enclosures engineered to reduce on-site labor from days to hours during initial builds or capacity expansions, a decisive advantage when you're racing a facility go-live date or executing a data-hall migration over a 72-hour weekend cutover window.
