Panduit FWUYL7575KAM026 24-Fiber OM5 Trunk Cable Assembly
The Panduit FWUYL7575KAM026 is a 24-fiber OM5 trunk cable assembly engineered for high-density data center deployments where space, performance, and safety compliance converge. Part of Panduit's QuickNet™ system, this 26-meter trunk features PanMPO female connectors on both ends, HD Flex cable construction that reclaims 30–40% of pathway space compared to traditional assemblies, and a Low Smoke Zero Halogen (LSZH) jacket for installations in enclosed or plenum-rated spaces. Ultra insertion loss performance and Method A polarity mapping deliver the predictable, low-loss connectivity that 40G/100G migration and short-wave division multiplexing (SWDM) applications demand.
Key Features
- OM5 fiber for extended reach and SWDM readiness: 50 µm multimode fiber supports 100GBASE-SR4 to 150 meters and enables future 200G/400G short-wave division multiplexing over existing infrastructure.
- 24-fiber PanMPO-to-PanMPO trunk: Female connectors on both ends interface with MPO adapter panels, breakout modules, or direct equipment ports; supports twelve duplex channels or two 12-fiber array connections.
- HD Flex cable saves 30–40% pathway space: Small-diameter trunk design reduces conduit fill and simplifies routing in overhead ladder rack, under-floor channels, and densely populated vertical cable managers.
- LSZH jacket for safety-critical environments: Low Smoke Zero Halogen construction meets IEC 60332-1 and IEC 61034 requirements for reduced toxic fume and smoke generation during fire events—essential for enclosed data halls and international projects.
- Ultra insertion loss specification: Factory-terminated and tested assemblies deliver <0.35 dB typical insertion loss per mating interface, preserving optical budget for long trunk runs and multi-tier architectures.
- Method A polarity mapping: Pin 1 to Pin 1 straight-through wiring at the connector level; integrators achieve bidirectional transmission by pairing Method A trunks with Method B crossover assemblies or flipping one connector at the adapter panel.
- HD Flex transition with pulling eye: One end terminated with a ruggedized pulling eye; enables low-friction installation through conduit and innerduct without stressing the fiber or connectors.
- 26-meter (85.3 ft) length: Precision-cut to support typical row-to-EOR (end-of-row) spans in modular data center designs; eliminates the service loop waste and clutter of over-length field-terminated solutions.
- Lime green jacket for instant OM5 identification: Color-coded per TIA-598 and ISO/IEC 11801 standards; reduces mis-patching risk during moves, adds, and changes in mixed-fiber-type environments.
- QuickNet™ pre-terminated system integration: Drop-in compatibility with Panduit's MPO cassettes, fiber adapter panels, and breakout harnesses; reduces installation labor by 70% compared to field splicing.
OM5 fiber—standardized as ISO/IEC 11801 and TIA-492-AAAD—extends the multimode roadmap beyond OM4's 100G/150m limit by adding short-wave division multiplexing (SWDM) capability. SWDM transmits four wavelengths (850, 880, 910, 940 nm) simultaneously over a single fiber pair, effectively quadrupling bandwidth without quadrupling fiber count. For 200GBASE-SR4 and 400GBASE-SR8 applications, OM5's lower modal dispersion at the 953 nm wavelength enables reach to 150 meters—50% farther than OM4—buying data center architects flexibility to centralize switching tiers or defer costly single-mode migrations. This trunk's HD Flex cable construction leverages Panduit's reduced-diameter jacket and optimized bend-radius design to free up 30–40% of cable tray and conduit capacity. In high-density row deployments where every cubic inch of overhead pathway is contested by power whips, copper DAC cables, and environmental monitoring runs, that space dividend translates directly into fewer pathway extensions, simpler routing geometry, and lower installation labor. The small bend radius (10× cable OD dynamic, 20× static) also simplifies dressing into vertical managers and threading through zero-U pass-throughs without introducing macro-bend attenuation—a failure mode that often surfaces months post-install when an over-stuffed bundle finally stresses individual fibers past the 1.5 mm radius threshold.
PanMPO connectors deliver sub-0.35 dB insertion loss through Panduit's precision-polished ferrule process and push-pull latch mechanism that maintains consistent ferrule pressure across hundreds of mate cycles. The female pin configuration on both ends of this trunk makes it a universal building block: mate directly to male equipment transceivers (QSFP28, QSFP-DD), interface with MPO-to-LC breakout cassettes for 10G server connectivity, or patch into MPO adapter panels for backbone consolidation. Method A polarity—straight pin 1 to pin 1 mapping—is the industry default for trunk-to-breakout topologies; achieve full duplex transmission by pairing this trunk with a Method B (key-up to key-down) crossover patch cord at the equipment end, or by rotating one connector 180° in a keyed adapter. Integrators managing large structured cabling projects will appreciate the color-coded polarity key system embossed on each connector boot (Method A = no key or white key per Panduit convention) and the included polarity verification report in each package—eliminating the field guesswork that leads to Tx/Rx swaps and truck rolls.
The LSZH jacket formulation meets IEC 60332-1 flame propagation limits and IEC 61034 <60% light obscuration requirements, making this trunk suitable for installation in cable containment spaces without dedicated air return plenums—common in EMEA and APAC data centers operating under EN 50174 and local fire codes. Unlike PVC-jacketed cables that release hydrochloric acid and dense black smoke during combustion, LSZH compounds decompose into water vapor and non-toxic particulates, preserving egress visibility and reducing corrosive damage to adjacent IT equipment. This is not a CMP (plenum) rated cable under NEC Article 770—U.S. installations in air-handling spaces require the LSZH/plenum hybrid rating or a separate CMP SKU. However, for enclosed wireway, conduit, and non-plenum ladder rack deployments, LSZH delivers equivalent mechanical durability to PVC with superior safety performance. The pulling eye termination on one end integrates a braided Kevlar strain relief that distributes tensile load across the entire cable jacket rather than concentrating stress at the connector backshell. Rated for 100 N (22.5 lbf) pulling tension, this design enables installation through horizontal conduit runs up to 100 feet or vertical riser conduit up to 50 feet without pre-lubrication or mid-point access boxes—reducing both material cost and installation time for long trunk routes.
This trunk ships with factory test reports documenting insertion loss, return loss, and length for every fiber in the array—verified against TIA-568-C.3 and IEC 61280-4-1 tier-1 test parameters using calibrated OTDR and light-source/power-meter equipment. Integrators can file these reports as part of as-built documentation for LEED, BICSI RCDD certification, or owner acceptance testing without repeating field measurements. The assembly is RoHS compliant for e-waste disposal tracking and meets TIA-604-5 (FOCIS-5) end-face geometry standards for MPO ferrule radius, apex offset, and fiber protrusion—the three variables that determine whether a connector will meet the <0.5 dB channel loss target in multi-tier backbone architectures. Panduit backs this trunk with a manufacturer warranty; register the installation within 90 days to activate extended coverage terms. For data center designs targeting 100G spine-leaf fabrics, 40G server aggregation, or future 200G/400G SWDM upgrades without forklift fiber replacement, the FWUYL7575KAM026 delivers the reach, density, and safety compliance that separates Tier III production environments from best-effort lab builds.
