Panduit FWUYL7575KNM025 OM5 24-Fiber PanMPO Trunk Cable Assembly
The Panduit FWUYL7575KNM025 is a 25-meter OM5 SigCore fiber optic trunk cable assembly engineered for high-density data center backbone and spine-leaf architectures. This 24-fiber trunk features PanMPO female connectors on both ends with Method A polarity, HD Flex small-diameter construction that reduces pathway congestion by 30-40%, and Low Smoke Zero Halogen (LSZH) jacket material meeting international fire safety standards. Factory-terminated and tested to Ultra Insertion Loss specifications, this lime-jacketed trunk delivers the performance headroom required for 40G/100G/400G parallel optics and short-wave division multiplexing (SWDM) applications across extended multimode reach.

OM5 fiber represents the latest generation of wideband multimode fiber optimized for short-wave division multiplexing (SWDM) and laser-optimized vertical-cavity surface-emitting laser (VCSEL) transmission. While backward-compatible with OM3 and OM4 infrastructure at 850nm, OM5 extends effective bandwidth across the 850-953nm spectrum, enabling four-wavelength SWDM transmission that quadruples capacity over a single duplex fiber pair. For 100GBASE-SR4 and 400GBASE-SR8 applications, OM5 delivers the same 100-meter reach as OM4, but provides additional margin for future 800G and 1.6T optics roadmaps using PAM4 modulation and higher-order SWDM. The 50-micron core diameter and optimized modal bandwidth ensure consistent performance across temperature ranges and installation stresses common in production data centers. This trunk uses Panduit's SigCore fiber, manufactured to exceed TIA-492-AAAD and IEC 60793-2-10 A1a.3 specifications with tightly controlled overfilled launch bandwidth and differential mode delay characteristics.
The PanMPO connector system is Panduit's enhanced implementation of the industry-standard MPO/MTP multi-fiber interface, incorporating precision-molded ferrules with sub-micron fiber endface geometry and enhanced guide pin retention. Each connector houses 12 fibers in a single row with 250-micron pitch, and this 24-fiber trunk utilizes two 12-fiber ribbons within the cable core. Method A polarity is configured as a "key-up to key-up" straight-through mapping, where Position 1 on the transmit end connects to Position 1 on the receive end—the standard pinout for parallel optics transceivers following TIA-568-C.3 guidelines. This trunk's female-to-female configuration is designed to mate with male PanMPO module cassettes, breakout panels, or patch cords in a structured cabling deployment. The Ultra Insertion Loss grade indicates maximum insertion loss of 0.35 dB per mating pair at 850nm (typical performance below 0.25 dB), with return loss exceeding 20 dB—performance margins that accommodate up to four additional mating cycles, temperature swings from -20°C to +70°C, and the cumulative loss budget of cassette-based breakout architectures. Each trunk ships with a serialized test report documenting per-fiber insertion loss and return loss measured at 850nm and 1300nm wavelengths using FOTP-171 methodology.
HD Flex cable construction reduces the overall cable diameter by incorporating smaller 900-micron tight-buffered fibers and a compact ribbon matrix, compared to traditional 2.0mm or 3.0mm loose-tube trunk designs. For a 24-fiber trunk, this translates to an outer diameter of approximately 8-9mm versus 12-15mm for conventional assemblies—a 30-40% reduction in cross-sectional area that directly impacts pathway fill capacity in cable trays, overhead ladder rack, and under-raised-floor routing. In high-density spine-leaf fabrics where hundreds of trunks converge at leaf and spine switches, this space efficiency prevents pathway congestion that forces costly infrastructure expansions or limits future scalability. The reduced diameter also improves bend radius performance, with a minimum bend radius under load of 10× cable diameter (approximately 80-90mm), allowing tighter routing around corners and through vertical risers without exceeding the fiber's macrobend loss limits. The lime LSZH jacket is rated for LSZH-3 per EN 50399 CPR classification, emitting less than 0.5% hydrogen chloride and producing smoke density below 60% light transmittance during combustion—critical for enclosed equipment rooms, under-floor pathways, and international installations governed by IEC or CENELEC fire codes where PVC-jacketed cables are prohibited.
This 25-meter length is optimized for intra-building data center interconnects: connecting leaf switches in the same row to a spine switch in an adjacent row, linking storage arrays to SAN fabrics within the same zone, or running from main distribution area (MDA) to horizontal distribution area (HDA) in a structured campus environment. For 40GBASE-SR4 and 100GBASE-SR4 applications, OM5 supports 100-meter reach (150 meters for 40G), providing ample margin for this 25-meter span plus additional slack for service loops and future rerouting. For 400GBASE-SR8 over eight duplex pairs (or two 24-fiber trunks with breakout), this assembly provides the same 100-meter OM5 reach. The PanMPO pinout supports breakout to duplex LC via MPO-to-LC cassettes or direct connection to 40G/100G QSFP/QSFP28 transceivers using MPO-to-MPO patch cords. As data centers migrate from 10G/25G leaf-spine fabrics to 100G/400G architectures, deploying OM5 trunks today ensures the physical layer supports future optics upgrades without re-cabling. Compliance with ISO/IEC 11801, TIA-568-C.3, TIA-604-5 (FOCIS-5 ferrule endface geometry), and RoHS environmental directives ensures this trunk integrates seamlessly into structured cabling systems audited for standards conformance and sustainability certifications required by enterprise procurement and green building programs.
