Panduit FWTYL7575LAM072 QuickNet 12-Fiber OM5 LSZH Trunk Cable Assembly - 72m
The Panduit FWTYL7575LAM072 is a factory-terminated 12-fiber OM5 trunk cable assembly engineered for high-density data center backbone deployments where 40/100/400 Gigabit Ethernet migration paths and constrained pathway capacity intersect. Built on 50-micron wideband multimode fiber with LSZH jacketing and spanning 72 meters (236 ft), this QuickNet trunk delivers 30-40% smaller cross-sectional area than legacy OM3 trunk designs while supporting short-wavelength division multiplexing (SWDM) for 4× lane efficiency over duplex fiber. Lime-colored for instant visual identification in mixed-infrastructure environments, it's designed for integrators managing spine-leaf topologies, row-based switch aggregation, or SAN consolidation projects where install speed, future bandwidth headroom, and fire-code compliance cannot be compromised.
Key Features
- Factory-terminated 12-fiber OM5 (50µm) trunk assembly for plug-and-play deployment
- 72-meter length supports extended horizontal runs, inter-row switch links, or floor-to-floor riser spans in multi-story facilities
- OM5 wideband multimode fiber enables SWDM operation: 100GBASE-SR4 over 2 fibers instead of 8, or 400G-SR4.2 over 8 fibers instead of 16
- LSZH (Low Smoke Zero Halogen) jacket rating meets IBC plenum and riser requirements without producing corrosive smoke or halogens during fire
- Small-diameter trunk design reduces pathway fill by 30-40% vs. traditional OM3 assemblies, critical for congested ladder rack and overhead tray installations
- Lime jacket color provides immediate visual distinction from OM3 (aqua) and OM4 (purple) trunks during MAC operations or troubleshooting
- Pre-terminated and 100% factory-tested for insertion loss and polarity—eliminates field termination labor, scrap, and rework
- Supports 40GBASE-SR4 to 150m, 100GBASE-SR4 to 150m, and future 400G-SR4.2 applications per TIA-492-AAAD specifications
- QuickNet branding: Panduit's engineered trunk platform with guaranteed performance and end-to-end warranty coverage
- RoHS compliant for global deployment and environmental compliance mandates
OM5 fiber—formally designated by TIA as "wideband multimode fiber"—represents the current state of the art in short-reach data center optics. Unlike OM3 and OM4, which are optimized for 850nm laser transmission, OM5 extends modal bandwidth certification across four distinct wavelengths (850, 880, 910, and 940nm). This multi-wavelength capability unlocks short-wavelength division multiplexing (SWDM), a parallel-optics alternative that reduces fiber pair count by 75% for a given data rate. In practical terms: a 100GBASE-SR4 link that would traditionally require 8 fibers (4 duplex pairs) over OM4 can run over just 2 fibers with OM5 SWDM transceivers. For 400 Gigabit Ethernet, SWDM allows 400G-SR4.2 transmission over 8 fibers instead of the 16 fibers required by conventional parallel optics. The FWTYL7575LAM072's 12-fiber count is specifically sized for dual 100G SWDM links with 4 fibers reserved for future expansion, or a single 400G SWDM link with 4-fiber redundancy—ideal for spine switch uplinks or storage array connectivity in leaf-spine fabrics. Panduit's factory polishing process ensures each connector end-face meets or exceeds TIA-604-5 (FOCIS-5) geometry limits for insertion loss ≤0.35 dB and return loss ≥-20 dB, validated via automated interferometry and optical time-domain reflectometry before the trunk leaves the manufacturing floor.
Trunk cable assemblies eliminate the three failure modes that plague field-terminated fiber: inconsistent polish quality, airborne contamination during termination, and incorrect polarity mapping. For contractors on fixed-price design-build engagements, this translates to predictable labor costs and zero rework risk. The 72-meter engineered length addresses the most common data center horizontal reach scenarios: end-of-row aggregation switches to mid-row server cabinets (≤60m), floor distributor to IDF riser conduit runs (≤70m), or pod-to-pod interconnects in modular data hall layouts. The LSZH jacket formulation—critical for installations subject to IBC Section 2702 or NFPA 70 Article 770—produces minimal smoke opacity and zero hydrochloric acid when exposed to flame, protecting both personnel egress visibility and sensitive electronics from corrosive gas damage during fire events. In high-density scenarios—40+ server racks per row, 10+ fiber trunks per ladder rack section—the small-diameter design matters: a 12-fiber OM5 trunk occupies roughly 60% of the cross-sectional area of an equivalent 12-fiber OM3 assembly, creating margin in 40% pathway fill calculations and reducing the need for costly cable tray additions or re-routes. Lime jacket color, while seemingly cosmetic, serves a functional role during MAC (Moves, Adds, Changes) work: installers can instantly differentiate OM5 infrastructure from legacy OM3 (aqua) or OM4 (erika violet) trunks without reading cable print legends, reducing the risk of cross-patching incompatible fiber grades and preventing the "why is my 100G link only training to 40G?" troubleshooting loops that waste billable hours.
The FWTYL7575LAM072 carries full certification to ISO/IEC 11801 Ed. 2.2 (international structured cabling), TIA/EIA-568-C.3 (optical fiber cabling components), TIA-492-AAAD (OM5 fiber performance), and IEC 60793-2-10 Type A1a.3 (wideband 50/125µm fiber), ensuring compatibility with enterprise campus standards, hyperscale data center design guides, and Department of Defense unified facilities criteria. For integrators spec'ing Cisco Nexus, Arista DCS, Juniper QFX, or Dell PowerSwitch platforms—all of which now ship 100G-SR4 and 400G-SR8 optics as standard—this trunk provides the physical-layer foundation to support both today's 10/25/40/100G mixed-rate environments and tomorrow's 200/400/800G migration without re-cabling pathways. The 12-fiber count aligns precisely with breakout strategies for QSFP-DD 400G transceivers, duplex-mode 100G links, or 4×25G breakout cables, making it the right-sized trunk for ToR (top-of-rack) to spine uplinks in leaf-spine designs or storage-network east-west traffic in NVMe-oF fabrics.
