Panduit FWUYL7575KNM005 24-Fiber OM5 Multimode Trunk Cable Assembly
The Panduit FWUYL7575KNM005 is a pre-terminated 24-fiber OM5 multimode trunk cable assembly built for high-density data center environments where fast deployment and extended reach matter. Part of Panduit's QuickNet™ system, this 5-meter lime-colored trunk uses small-diameter cable construction to save 30-40% pathway space compared to traditional 24-fiber assemblies, letting you pack more circuits into congested overhead trays, under-floor channels, or vertical cable managers without sacrificing bend-radius compliance. Factory-terminated MTP/MPO connectors on both ends eliminate field splicing, cut installation labor by hours per trunk, and deliver guaranteed insertion loss performance out of the box.
Key Features
- OM5 Wideband Multimode Fiber (WBMMF) — 50 µm core optimized for short-wave wavelength-division multiplexing (SWDM), supporting 40/100 Gigabit Ethernet over 150m and future 200/400GbE applications on existing installed base
- 24-Fiber MTP/MPO Trunk Architecture — Pre-terminated connectors on both ends with push-pull boot design for quick mating in confined panel spaces; supports 12-strand or 24-strand breakout cassettes downstream
- 30-40% Space Savings — Small-diameter trunk cable reduces bundle cross-section, freeing valuable pathway capacity for power feeds, copper links, or future fiber additions without tray upgrades
- LSZH Jacket (Low Smoke Zero Halogen) — IEC 60332-3C flame-rated outer sheath produces minimal smoke and no corrosive halogen gases during combustion; meets European EN50575 CPR Class Cca requirements for enclosed building pathways
- Lime Identification — High-visibility jacket color simplifies OM5 circuit tracing in mixed-fiber environments (OM3 aqua, OM4 erika violet, OM5 lime); reduces mis-patching risk during MAC work
- Factory-Tested Polarity & Loss — Each trunk ships with test report documenting IL ≤0.35 dB typical per mating interface, Method B polarity (standard Ethernet/Fibre Channel transmit-to-receive mapping), and connector end-face geometry per IEC 61755-3-31
- QuickNet™ System Integration — Drop-in compatibility with Panduit fiber enclosures, cassette modules, and zone distribution boxes; no adapter swaps or polarity flips needed when pairing with Panduit breakout hardware
- 5-Meter Reach — 16.4-foot cable length suits top-of-rack to end-of-row aggregation switch connections, intra-row cross-connects, or overhead pathway drops to wall-mounted zone boxes; specify longer assemblies for inter-row or cross-aisle links
OM5 fiber (TIA-492-AAAD / IEC 60793-2-10 type A1a.3) uses the same 50 µm core and 850 nm LED launch conditions as OM3 and OM4, but adds laser-optimized performance across four distinct short-wave wavelengths: 850, 880, 910, and 940 nm. This wideband capability lets SWDM transceivers send parallel 25 Gbps or 50 Gbps lanes down a single duplex fiber pair instead of requiring eight or four fibers per 100G link, cutting connector density on spine switches by 75% and future-proofing trunk infrastructure for 200/400 Gigabit upgrades without re-cabling backbone pathways. When deployed with SWDM optics, OM5 delivers 100GBASE-SR2 over 100 meters or 200GBASE-SR4 over 70 meters—sufficient for intra-building data center fabrics. For traditional parallel optics (40GBASE-SR4, 100GBASE-SR4), OM5 matches or exceeds OM4 reach: 150 meters at 100 Gbps, 100 meters at 40 Gbps. The FWUYL7575KNM005 trunk gives you both deployment options in one cable plant.
Trunk cable assemblies shift termination from the field to the factory floor, where automated polishing, epoxy-cure ovens, and interferometric inspection eliminate the variability of hand-work. Each MTP/MPO connector on this assembly is polished to less than 50 nm apex offset and under 0.15 µm fiber undercut, ensuring physical-contact mating across all 24 fibers without air gaps that scatter light or moisture ingress that degrades long-term loss. Push-pull boots speed insertion and extraction in 1U panel slots or high-density cassette arrays—no twisting or rocking required—and protect the connector ferrule during handling. Because both ends are factory-installed, the trunk can route through J-hooks, cable trays, and floor grommets without exposing fragile fiber ends to contamination or breakage. On install day, two technicians can deploy a dozen 24-fiber trunks in the time it would take to splice and test a single 288-fiber backbone—critical when you're racing a data hall commissioning deadline or executing after-hours cutovers with narrow maintenance windows.
The small-diameter cable construction uses tight-buffered 900 µm fibers in a reduced-size central tube, wrapped with aramid strength members and extruded LSZH outer jacket. Finished outer diameter runs 30-40% smaller than legacy loose-tube or ribbonized 24-fiber designs, translating to meaningful pathway savings: a four-inch ladder rack that would hold eight standard trunks can fit twelve to fourteen of these assemblies in the same fill ratio, preserving airflow and leaving reserve capacity for unplanned circuit adds. In vertical cable managers or overhead wire mesh trays, the weight reduction (smaller cable = less jacket and filler material) eases support-structure loading and simplifies securing bundles with hook-and-loop straps. Bend radius remains a safe 10× cable OD (loaded) and 15× OD (unloaded), so you won't kink fibers when dressing trunks around tight corners or routing through congested patch fields. Lime jacket color provides instant visual differentiation from aqua OM3 and purple OM4 links, reducing the risk of accidentally patching a 10G transceiver into an OM5 trunk (no harm done) or mistaking an OM3 uplink for an OM5 spine connection during troubleshooting.
The assembly ships as part of Panduit's QuickNet pre-terminated fiber system, designed for plug-and-play integration with Panduit's FHD fiber enclosures, FAP adapter panels, and cassette modules. Method B polarity (TIA-568-C.0 Annex A) is standard: Position 1 on end A maps to Position 12 on end B, Position 2 to Position 11, and so forth, flipping the array so transmit fibers on one switch meet receive fibers on the peer—exactly what BASE-SR4 and 40G/100G parallel optics expect. Pair this trunk with Panduit's 24-fiber breakout cassettes (MTP-to-LC or MTP-to-duplex-SC modules) and you'll land all 24 strands into individually accessible duplex ports in two rack units or less, no fusion splicer or polish jigs required. If your enclosure uses non-Panduit cassettes, verify adapter key orientation (key-up versus key-down) and polarity method (A, B, or C) before ordering; the MTP/MPO interface is mechanically universal, but polarity mismatches will swap transmit and receive, lighting link LEDs red.
LSZH jacketing meets IEC 60332-3C vertical flame propagation limits and produces less than 0.5% hydrogen chloride emission under combustion (IEC 60754-1), satisfying European Construction Products Regulation (CPR) Class Cca requirements and U.S. building codes that mandate low-smoke cable in return-air plenums or enclosed riser shafts. In the event of a cable-tray fire, LSZH jackets generate optically thin white smoke instead of dense black PVC soot, preserving visibility for evacuation and reducing cleanup costs after suppression system discharge. Corrosive halogen gases (chlorine, fluorine) that attack server electronics, corrode copper busbars, and damage HVAC coils are absent, protecting tens of millions of dollars in adjacent capital equipment. If you're installing in a Tier III or Tier IV data hall with stringent fire-safety standards—or retrofitting older raised-floor spaces that predate modern smoke codes—LSZH jackets are often non-negotiable. This assembly gives you that compliance out of the box.
Each trunk is serialized and ships with a certificate of compliance documenting insertion loss, return loss, and polarity verification across all 24 fibers. Typical IL at 850 nm measures ≤0.35 dB per mating pair (connector plus bulkhead adapter plus connector), well under the 0.75 dB TIA channel budget allocation for two connections. Return loss exceeds 20 dB, ensuring that reflected light won't saturate transceiver receivers or introduce bit errors on high-speed links. Ferrule end-face geometry—radius of curvature, apex offset, fiber height—is interferometrically inspected and recorded; out-of-spec connectors are rejected before the cable leaves the factory. You can file these test reports with your as-built documentation or hand them to commissioning engineers during acceptance testing, proving Day One compliance with TIA-568-C.3 Tier 1 (basic) or Tier 2 (extended) performance requirements.
The 5-meter (16.4-foot) length handles the majority of intra-row data center connections: top-of-rack access switch to aggregation switch at the end of the row, middle-of-row patch panel to overhead zone distribution box, or spine switch to spine switch in adjacent racks (assuming back-to-back or side-by-side placement). It's short enough to keep cable dressing clean and pathway congestion low, but long enough to route through wire-mesh trays, drop down vertical managers, and leave service slack at each end for future re-patching. If you need to span longer distances—cross-aisle aggregation, inter-pod links, or connections to a centralized main distribution area—Panduit manufactures the same assembly in 10m, 15m, 30m, and custom lengths up to 100m (consult OM5 distance limits: 150m at 100G with SR4 optics, 100m at 40G). For shorter jumps (rack-to-rack within the same row, or switch-to-cassette inside an enclosure), consider 2m or 3m trunks to minimize excess cable coils that trap heat and clutter airflow paths.
Installation is drop-in: route the trunk through your chosen pathway, remove the dust caps from both MTP connectors (save caps for reuse if you ever decommission the link), align the connector key with the adapter or cassette key slot (key-up is standard for Method B polarity), and push until you hear the latch click. The push-pull boot lets you extract the connector by squeezing the tab and pulling straight back—no twisting or rocking that can scratch the ferrule or bend guide pins. For permanent installations, secure the trunk to cable trays or J-hooks every 4-5 feet with hook-and-loop straps (never use zip ties on fiber—pinch points cause microbending loss), leave a service loop near each termination point (1-2 feet), and label both ends with circuit ID and destination using Panduit's self-laminating fiber labels or a label printer loaded with outdoor-grade polyester tape. If you're patching into an enclosure with limited depth, remember that MTP boots add ~50 mm to the connector length; plan panel layout accordingly or spec low-profile boots on your next order.
This assembly meets TIA-568-C.3 performance standards for multimode premises cabling, TIA-604-5 (FOCIS-5) mechanical interface specs for MTP/MPO connectors, ISO/IEC 11801 Edition 2.2 Category OM5 requirements, and TIA-492-AAAD fiber specifications for laser-optimized 50 µm multimode. RoHS-compliant construction (lead-free, mercury-free, cadmium-free) satisfies European Union Directive 2011/65/EU and its updates, clearing the trunk for use in EU data centers or multinational campuses with global procurement standards. Panduit's manufacturing process is ISO 9001-certified, and the QuickNet product line carries a 25-year system warranty when installed per Panduit guidelines—covering cable, connectors, and cassettes as a unified channel, not just individual components. That warranty hinges on using Panduit-branded hardware end-to-end (trunk + cassette + enclosure + patch cords) and following published installation practices (don't exceed bend radius, don't over-torque mounting screws, don't re-polish connectors in the field). If you mix vendors, you still get Panduit's standard product warranty, but the 25-year system assurance drops off.
The Panduit FWUYL7575KNM005 delivers the trifecta every data center build demands: faster deployment (factory terminations eliminate field labor), higher density (small-diameter cable frees pathway capacity for growth), and guaranteed performance (OM5 future-proofs the plant for 200/400G SWDM upgrades). Whether you're wiring a greenfield hyperscale pod, refreshing a legacy Fibre Channel SAN with Ethernet fabrics, or adding spine capacity to an existing leaf-spine network, this trunk assembly turns a multi-day splicing project into a same-day plug-and-play install—without sacrificing the test data, polarity assurance, or build quality that Tier III/IV operations require.
