Panduit FWUYL7575LAM055 QuickNet OM5 24-Fiber Trunk Cable Assembly
The Panduit FWUYL7575LAM055 is a 55-meter, 24-fiber OM5 trunk cable assembly engineered for high-density datacenter backbone installations requiring extended reach and minimal pathway congestion. Built on Panduit's QuickNet platform, this pre-terminated assembly pairs PanMPO female connectors at both ends with HD Flex small-diameter trunk cable, delivering Method B polarity and Ultra insertion loss performance in a low smoke zero halogen jacket. The lime-green OM5 fiber supports wideband multimode transmission from 850 to 950 nm, future-proofing your infrastructure for short-wavelength division multiplexing (SWDM) and 400G/800G migration paths while maintaining full backward compatibility with legacy OM3/OM4 optics.
Key Features
- OM5 wideband multimode fiber (50 µm core) supports 40G/100G SR4, 100G SR10, 200G/400G SR8, and emerging SWDM4 applications at 850-950 nm wavelengths
- 24-fiber count in PanMPO female-to-female configuration provides 12 duplex channels or 2× 12-fiber base-8 breakouts for spine-leaf architectures
- HD Flex small-diameter trunk cable uses 30-40% less conduit and cable-tray space compared to standard round trunk assemblies, critical for congested hot-aisle pathways
- Method B polarity scheme (flipped array) enables straight-through duplex transmission when mated to Method A patch cords or cassettes without crossover adapters
- Ultra insertion loss grade guarantees ≤0.35 dB per mated connector pair (vs. ≤0.75 dB standard), preserving link budget on extended 55-meter runs
- Low smoke zero halogen (LSZH) jacket meets IEC 60332-1 and IEC 61034 for flame spread and smoke density, required for under-floor and overhead plenum installations in occupied spaces
- Integrated pulling eye on one cable end simplifies conduit and cable-tray installation, allowing attachment of pull rope without custom hardware or risk of connector damage
- Factory-terminated and tested assemblies ship ready to deploy, eliminating field termination labor, consumables cost, and the 12-48 hour cure time associated with epoxy-polish connectors
The 55-meter length positions this trunk for row-to-end-of-row (EOR) or row-to-middle-of-row (MOR) switch aggregation in large colocation or enterprise datacenter pods. At 180 feet, you can span from a top-of-rack switch stack at the far end of a 15-rack row back to a centralized spine switch in an adjacent hot aisle, or bridge across four to five server rows in a leaf-spine topology without requiring an intermediate fiber panel. OM5 fiber's extended bandwidth—4700 MHz·km effective modal bandwidth at 850 nm, nearly double OM4's 4700 MHz·km at the same wavelength—means you can push 100GBASE-SR4 to 150 meters or plan for future 400GBASE-SR8 links at 100 meters, both well within this assembly's 55-meter span. The HD Flex cable construction replaces bulky round jacketing with a flexible flat or oval profile that stacks cleanly in horizontal cable trays and bends around tight corners without kinking, a necessity when routing through ladder rack with existing copper and power distribution. Panduit's Ultra insertion loss specification (factory-tested to ≤0.35 dB per connection) matters on these longer runs: a traditional 0.75 dB MPO connection would consume 1.5 dB of your link budget for the two mated connector pairs (trunk to patch cord at each end), whereas Ultra-grade connectors hold that loss to 0.7 dB, leaving more margin for splices, patch-cord connections, and aging. The lime-green OM5 jacket provides instant visual identification in mixed-fiber environments—critical when you're troubleshooting a 400G link at 2 a.m. and need to confirm you're tracing the correct OM5 trunk rather than an adjacent OM3 or OM4 run.
Method B polarity is the de facto standard for MPO trunk deployments in structured cabling systems. This assembly presents a flipped fiber array (position 1 maps to position 12, position 2 to position 11, and so on) so that when you connect it to a Method A patch cord or cassette—where the array is straight-through—you achieve the transmit-to-receive crossover required for duplex communication. In practice, you'd install this trunk between two fiber panels or between a panel and a switch with MPO ports, then use standard Method A duplex LC or MPO patch cords on either side. The PanMPO connector is Panduit's implementation of the IEC 61754-7 MPO interface (commonly referred to as MTP in Corning-licensed products), featuring a metal guide-pin housing and push-pull boot that meets TIA-604-5 (FOCIS-5) mechanical and optical specifications. Female MPO connectors lack guide pins and accept a male MPO (with pins) for mating; this female-to-female configuration requires a male-pinned bulkhead adapter or patch cord at each end, which is standard practice in panel-based architectures. The 24-fiber count maps to 12 duplex LC channels when broken out via cassettes, or remains as a native 2× 12-fiber MPO link for switch modules with MPO ports (common in 100G/400G spine switches). For a typical leaf-spine deployment, you'd pull this trunk from the leaf switch at the end of a row to an intermediate patch panel, break it out to 12 duplex LC connections, and patch individual 10G or 25G server uplinks, or leave it intact as a single 100G or 400G uplink to the spine.
The LSZH jacket is rated for plenum and riser use under IEC 60332-1 flame-spread and IEC 61034 smoke-density standards, making it compliant with European EN 50575 CPR (Construction Products Regulation) Class B2ca requirements and suitable for installation in occupied under-floor spaces or overhead cable trays where PVC combustion byproducts would pose a life-safety risk. In North American installations, verify local fire-marshal interpretation—some jurisdictions accept LSZH as a riser-rated cable (CMR equivalent) but still require OFNP-rated cable for true plenum spaces; others recognize LSZH under special-application provisions. The integrated pulling eye simplifies installation in long conduit runs or vertical risers: attach your pull rope with a standard swivel connector, apply steady tension (Panduit recommends ≤90 kg / 200 lb pull force for HD Flex trunk), and the eye distributes load across the cable strength member rather than stressing the connector boot or furcation point. This assembly meets ISO/IEC 11801 Edition 2.2, TIA-568-C.3 (optical fiber cabling components), TIA-492-AAAD (OM5 fiber performance), and IEC 60793-2-10 Type A1a.3 (50/125 µm graded-index fiber), ensuring interoperability with any standards-compliant OM5 transceiver or media converter. For deployment planning, pair this trunk with Panduit's FMT or FQMM cassette modules at the panel end, Panduit method-A duplex LC patch cords for server connections, and 40G/100G/400G SR optics rated for OM5 fiber—this combination delivers a fully warranted, pre-validated channel that eliminates finger-pointing during acceptance testing and gives you a clear path from 10G server access today to 400G spine uplinks tomorrow without re-cabling the backbone.
