Panduit FWUYL7575KNM029 OM5 QuickNet 24-Fiber Trunk Cable Assembly
The Panduit FWUYL7575KNM029 is a factory-terminated OM5 trunk cable assembly engineered for high-density data center backbones migrating to 400GBASE-SR8, 800GBASE-SR8, and future wideband multimode applications. This 29-meter (95-foot) QuickNet trunk delivers 24 fibers of OM5 SigCore performance in a PanMPO Female to PanMPO Female configuration with Method A polarity, HD Flex small-diameter construction, and Low Smoke Zero Halogen jacket compliance. Purpose-built for rapid deployment in space-constrained environments, it eliminates field termination, reduces pathway congestion by 30-40%, and provides ultra-low insertion loss for extended-reach 100-meter OM5 channels.

OM5 fiber represents the latest evolution in multimode technology, optimized for short-wavelength division multiplexing (SWDM) in the 850-950nm range. Unlike OM3 and OM4, which specify bandwidth at 850nm only, OM5 adds a second bandwidth specification at 953nm (4700 MHz·km minimum), enabling four-wavelength SWDM optics to deliver 100 Gbps over a single duplex LC or 400 Gbps over an 8-fiber MPO interface across 100-meter distances. This FWUYL7575KNM029 trunk uses Panduit SigCore OM5 fiber with 50μm core diameter and optimized refractive index profile, maintaining 3500 MHz·km at 850nm for backward compatibility with existing OM3/OM4 optics while future-proofing for next-generation SWDM transceivers. The PanMPO connectors are Panduit's implementation of the MPO multi-fiber interface, manufactured to ultra-tight geometric tolerances for sub-0.35 dB insertion loss per mated pair (typical 0.15 dB). Method A polarity—also called "straight-through" or "key-up-to-key-up"—mirrors fiber positions across both connectors, requiring a crossover somewhere in the channel (either at the cassette, module, or via a Type B cable). The 24-fiber count aligns with industry-standard breakout cassettes: install this trunk into a 24-fiber MTP/MPO cassette, break out to 12 duplex LC ports, and you've built a 12-lane 10G/25G/100G infrastructure in under an hour. For 400G-SR8 or 800G-SR8 parallel optics, the full 24 fibers can be split into transmit and receive groups, delivering the 8 or 16 lanes required for these emerging IEEE 802.3 standards.
The HD Flex designation refers to Panduit's high-density trunk cable construction, which uses smaller-diameter buffer tubes and tighter bundling to achieve 30-40% space savings compared to traditional round trunk cables. In a 4-inch backbone pathway shared by power, copper, and fiber, every millimeter of diameter reduction matters—this trunk's slim profile allows you to route additional cables without exceeding the 40% fill ratio mandated by TIA-569 or triggering airflow blockage in overhead ladder rack. The reduced bend radius (typically 10× cable OD under load) means tighter turns around vertical riser bends and cabinet entries, critical when retrofitting older data centers with limited clearance. Despite the compact geometry, the LSZH jacket meets stringent flame and smoke ratings: it will not propagate fire (IEC 60332-3 vertical tray test) and emits minimal halogen acid gases under combustion, a requirement for European CENELEC installations and increasingly adopted in U.S. hyperscale facilities. The lime jacket color provides instant visual identification of OM5 cabling per TIA-598-D Appendix A, preventing the accidental cross-patching with OM3 (aqua) or OM4 (Erika violet) infrastructure that can compromise link budgets. At 29 meters, this trunk fits the typical main distribution area (MDA) to horizontal distribution area (HDA) backbone run in modular data centers, or spans between adjacent rows in a large colocation floor. The factory-applied PanMPO connectors are individually insertion-loss tested and certified, with test reports traceable to the assembly serial number—eliminating the field labor, fusion splicer investment, and OTDR validation overhead of on-site termination.
QuickNet factory-terminated assemblies are Panduit's answer to the reliability and schedule risks of field termination. Every trunk ships with documented insertion loss values, return loss specs, and end-face geometry inspection images captured during manufacturing. This traceability is critical for TIA-568-C.3 Tier 2 certification and for operators managing large-scale 400G migrations where a single bad connector can force a truck roll and maintenance window. The PanMPO interface uses a push-pull boot design with integrated dust caps, rated for 500+ mating cycles without performance degradation. The 24-fiber configuration supports both 12-fiber duplex breakout cassettes (e.g., Panduit FAP series) and direct connection to 24-fiber parallel optics, giving you flexibility as transceiver technology evolves from 100G-SR4 (12-fiber) to 400G-SR8 (16-fiber) to 800G-SR8 (16-fiber with additional redundancy). Method A polarity is the most common architecture in structured cabling systems because it allows straight-through trunks in the backbone with polarity inversion handled by plug-and-play cassettes or array cables at the equipment end, simplifying inventory management and reducing the risk of incorrect fiber pairing during moves, adds, and changes.
