Panduit FWTYL7575LNM038 QuickNet OM5 12-Fiber Trunk Cable Assembly
The Panduit FWTYL7575LNM038 is a 38-meter OM5 trunk cable assembly engineered for high-density data center deployments requiring extended reach and future-proof bandwidth. This 12-fiber trunk features PanMPO female connectors on both ends with Method B polarity, Ultra Insertion Loss performance, and LSZH jacketing—designed to support 100GBASE-SR4, 400GBASE-SR16, and emerging 800G/1.6T applications while consuming 30-40% less pathway space than traditional trunk assemblies. The lime-colored jacket provides instant visual identification in mixed OM3/OM4/OM5 installations.
Key Features
- OM5 Wideband Multimode Fiber: 50-micron core supports shortwave wavelength division multiplexing (SWDM) for 100G over 150m, 400G over 100m, enabling parallel-optics migration without re-cabling
- Ultra Insertion Loss Grade: Factory-terminated and tested to deliver maximum optical performance with minimal signal degradation across all 12 fibers
- PanMPO Female to PanMPO Female: Compatible with Panduit's Signature Core infrastructure; push-pull boots and precision ferrule alignment ensure repeatable <0.35 dB IL per connection
- Method B Polarity (Key-Up to Key-Up): Straight-through pin configuration simplifies 40G/100G QSFP deployments and eliminates polarity-flip errors in spine-leaf topologies
- 38-Meter Extended Reach: 124.67-foot length bridges cross-row or cross-pod connections in larger data halls without mid-span splice points
- LSZH Jacket (Low Smoke Zero Halogen): IEC 60332-3-24 compliant for plenum-equivalent fire safety in air-handling spaces and under-raised-floor pathways
- High-Density Cable Design: 2.9mm trunk diameter reduces bundle cross-section by 30-40%, freeing conduit fill and improving airflow in densely packed vertical managers
- Lime Color Coding: Matches TIA-598-D OM5 identification standard; prevents accidental cross-patching with OM3 (aqua) or OM4 (erika violet) links
- Factory Pre-Terminated: Eliminates field termination labor and variability; each assembly ships with individual test report documenting IL/RL per fiber pair
- QuickNet Modular System: Integrates with Panduit cassettes, breakout modules, and patch panels for scalable 12F-to-LC or 12F-to-12F architectures
OM5 fiber represents the current endpoint of ISO/IEC 11801 multimode standards, engineered specifically to support emerging short-reach data center protocols that leverage four or more wavelengths simultaneously. While OM3 and OM4 fibers are optimized for 850nm laser transmission, OM5 maintains the same 850nm performance but adds wide-bandwidth capability across 850nm, 880nm, 910nm, and 940nm windows. This wideband characteristic—quantified by the effective modal bandwidth (EMBc) specification—allows SWDM transceivers to transmit four independent 25G or 50G channels over a single fiber pair, quadrupling effective capacity without increasing fiber count. For 100GBASE-SR4 links, this trunk's 12 fibers break out into one transmit lane and one receive lane per direction, supporting a full 100G bidirectional path within a single assembly. For 400GBASE-SR16, all 12 fibers engage: eight transmit, four receive (or vice versa depending on polarity), pushing aggregate throughput to 400 Gbps over distances up to 100 meters. The Ultra Insertion Loss grade ensures every connector interface—whether direct-attach or via mating adapter—stays within the IEEE 802.3 power budget, even after multiple mate/unmate cycles. Panduit's factory termination process uses automated ferrule polishing and interferometric end-face inspection to guarantee <0.35 dB insertion loss and >20 dB return loss per fiber, eliminating the variability and contamination risk inherent in field-terminated MPO assemblies.
In hyperscale and enterprise data centers, this trunk serves as a spine-to-leaf interconnect in 100G/400G Clos fabrics, a storage-area-network (SAN) trunk linking FC32 or NVMe-oF arrays, or as intra-rack vertical cabling consolidating twelve duplex LC connections into a single pull. The 38-meter length is purpose-built for cross-aisle or cross-pod runs—long enough to span two rows of racks (typical row depth 12-15 meters plus vertical rise and horizontal service loop) yet short enough to stay within OM5's 150-meter 100GBASE-SR4 channel limit with headroom for patch cords. Method B polarity (key-up both ends, straight-through pin mapping) is the de facto standard for QSFP-based switch fabrics: QSFP28 and QSFP56-DD modules expect a straight-through trunk so the transceiver's internal crossover handles transmit/receive lane assignment. Deploying Method B trunks with Type-B (key-up/key-down) cassettes or breakout modules produces a correct A-to-B duplex LC polarity at the device layer without requiring field polarity inversion or A/B cable swaps. The LSZH jacket meets fire and smoke requirements for data centers built to ASHRAE TC 9.9 or European EN 50173 standards, which often prohibit PVC-jacketed cable in air-return plenums or under-floor cooling zones. Lime jacketing provides instant visual differentiation from legacy OM3/OM4 infrastructure, reducing the chance of accidentally patching a 400G port into an OM4 link rated for only 150-meter 100G reach. The reduced-diameter trunk construction—achieved through tight-buffered 900-micron subunits rather than traditional 2mm or 3mm loose-tube designs—cuts pathway congestion: a 24-strand OM5 trunk occupies roughly the same cross-sectional area as a single Cat6A copper patch cord, enabling 10:1 or higher fiber-to-copper density ratios in vertical managers and overhead ladder rack.
This assembly ships with full test documentation traceable to TIA-568-C.3 and ISO/IEC 11801 standards, includes dust caps on both connectors, and carries Panduit's manufacturer warranty. Meets TIA-492-AAAD (OM5 fiber performance), IEC 60793-2-10 Type A1a.3 (fiber geometry), TIA-604-5 FOCIS-5 (MPO connector interface), RoHS compliance for hazardous substance restrictions, and IEC 60332-3-24 flame propagation requirements. For data center operators future-proofing 100G leaf-spine fabrics or deploying 400G uplinks today, the FWTYL7575LNM038 delivers factory-certified performance, standards-based polarity, and the pathway efficiency required to scale fiber counts without triggering costly conduit or cable-tray expansions.
