Panduit FWUYL7575KAM052 24-Fiber OM5 QuickNet™ Trunk Cable Assembly
The Panduit FWUYL7575KAM052 is a 24-fiber OM5 pre-terminated trunk cable assembly engineered for high-density data center deployments where space, speed, and future bandwidth capacity are critical. Part of Panduit's QuickNet™ system, this 52-meter trunk features PanMPO female connectors on both ends, HD Flex small-diameter cable construction, and Ultra Insertion Loss performance—delivering 30 to 40% space savings over traditional trunk assemblies while eliminating field termination risk. The low smoke zero halogen (LSZH) jacket meets international flammability standards for occupied spaces and equipment rooms.
Key Features
- OM5 wideband multimode fiber supports shortwave wavelength division multiplexing (SWDM) for 40GBASE-SR4, 100GBASE-SR4, and future 200G/400G applications
- 24-fiber capacity in dual-row PanMPO female-to-female configuration for high-density backbone connections
- HD Flex cable design reduces outer diameter by 30-40% compared to standard trunk cables—critical for conduit fill and pathway congestion
- Ultra Insertion Loss grade ensures performance headroom beyond TIA-568-C.3 minimum requirements
- Low smoke zero halogen (LSZH) jacket rated IEC 60332-1 for plenum and international installations
- Method A polarity (straight-through key-up-to-key-up) pairs with Method B cassettes or adapters for proper transmit/receive alignment
- Integrated pulling eye on one end simplifies installation through conduit, innerduct, or cable tray
- 52-meter engineered length suits typical intra-building riser, horizontal, or zone distribution runs
- Factory-terminated and tested—eliminates field splicing labor, consumables, and insertion loss variability
- Lime-colored jacket provides immediate OM5 fiber type identification per TIA-598-D color coding standards
OM5 fiber represents the latest generation of wideband multimode technology, optimized for 850 nm VCSEL transmission while supporting shortwave wavelength division multiplexing (SWDM) across four wavelengths (850/880/910/940 nm). This capability allows a single 24-fiber trunk to support twelve 100GBASE-SR4 links or six bidirectional 100G connections using parallel optics—double the effective density of OM3/OM4 fiber at the same physical fiber count. The 50-micron core diameter maintains backward compatibility with existing OM3 and OM4 infrastructure while future-proofing for 200G and 400G Ethernet migrations. Panduit's PanMPO connector system uses precision MT ferrules with 12-fiber rows arranged in a 2x12 configuration for the 24-fiber assembly. Female connectors on both ends accommodate standard MPO adapter panels or direct connection to switch/server MPO ports. Method A polarity—also called "straight-through" or "key-up-to-key-up"—maintains fiber position 1-to-1 and 12-to-12 through the trunk; when paired with Method B cassettes (which cross fibers internally) or key-up-to-key-down adapters, proper transmit-to-receive mapping is maintained for duplex and parallel optic transceivers. The Ultra Insertion Loss designation indicates factory performance testing to a tighter tolerance than the 0.75 dB maximum specified in TIA-568-C.3 for MPO connections, providing link budget headroom for multi-connection channels or marginal transceiver output power.
HD Flex cable construction addresses the single largest constraint in modern data center builds: pathway congestion. Traditional 24-fiber trunk assemblies use round jackets with outer diameters near 10 mm; Panduit's HD Flex design reduces this to approximately 6.5 mm through optimized buffering and flat-profile construction. This 35-40% reduction in cross-sectional area translates directly to conduit fill capacity—a 1-inch innerduct that accommodates three standard trunks can fit five HD Flex trunks under NEC Chapter 9 Table 1 fill rules. In overhead cable tray or under-floor distribution, the smaller profile reduces weight per linear foot and eases bend radius requirements around corners or transitions. The 52-meter length is engineered for common intra-building deployments: equipment room to intermediate distribution frame (IDF), floor-to-floor riser runs in multi-story facilities, or horizontal zone cabling in large single-floor data halls. The integrated pulling eye—a reinforced loop attached to the cable strength member—accepts pull tape or fish line for installation through conduit or J-hooks without stressing the fiber or connectors. For long pulls, the installer stages the trunk in sections and transfers the pull force to the pulling eye rather than the connector boots, preventing ferrule damage or fiber compression. Low smoke zero halogen jacketing is mandated by international building codes (IEC, CENELEC) and increasingly specified in domestic projects for occupied spaces, under-floor plenums, and equipment rooms where PVC combustion products (hydrochloric acid, dioxins) pose life-safety and equipment risks. The LSZH compound meets IEC 60332-1 vertical flame propagation and IEC 61034 smoke density limits while maintaining flexibility and abrasion resistance.
This trunk assembly is tested and certified to ISO/IEC 11801 (international structured cabling), TIA-568-C.3 (North American optical fiber standard), TIA-604-5 (FOCIS-5 MPO connector performance), and TIA-492-AAAD (OM5 fiber specifications). RoHS compliance ensures restriction of hazardous substances (lead, mercury, cadmium, hexavalent chromium) for European and global markets. As part of the QuickNet pre-terminated system, the FWUYL7575KAM052 integrates with Panduit fiber cassettes, patch panels, enclosures, and transition modules—enabling modular, scalable architectures where trunk-and-cassette topology replaces traditional fusion splicing. For spine-leaf data center fabrics, leaf switches connect to spine switches via these trunk assemblies, with breakout cassettes at each end fanning out to individual duplex LC patch cords for transceiver connections. The lime jacket color provides instant visual confirmation of OM5 fiber type during installation and maintenance, reducing the risk of mismatched fiber grades in mixed OM3/OM4/OM5 environments. Panduit's factory termination process includes end-face inspection, insertion loss testing, and protective dust caps on each connector, ensuring the trunk arrives ready for deployment with performance guaranteed from the factory.
