Panduit FWTYL7575LAM038 QuickNet™ 12-Fiber OM5 Trunk Cable Assembly
The Panduit FWTYL7575LAM038 is a 12-fiber OM5 trunk cable assembly engineered for data center deployments requiring both extended reach and high-density routing. This 38-meter (124.67 ft) QuickNet™ trunk delivers multimode connectivity optimized for 100GBASE-SR4 and 400GBASE-SR8 applications while occupying 30 to 40% less pathway space than standard assemblies. OM5 wideband multimode fiber supports shortwave wavelength division multiplexing (SWDM), enabling 100G transmission over distances up to 150 meters on duplex fiber and 400G over 100 meters on parallel optics—critical for spine-leaf architectures and cross-aisle connections. The lime jacket provides rapid visual identification in mixed-fiber environments, and LSZH flammability rating meets plenum and riser installation codes for enclosed cable pathways. Factory-terminated assemblies eliminate field splicing, reduce deployment time, and ensure consistent insertion loss across all 12 fibers.

OM5 Wideband Multimode for 100G and 400G Data Center Fabrics
OM5 fiber extends the reach and lane efficiency of multimode infrastructures beyond what OM3 and OM4 can deliver. Where OM4 supports 100GBASE-SR4 to 100 meters and 400GBASE-SR8 to 70 meters over 8 or 16 fibers, OM5's wideband characteristic—specified across four distinct wavelengths (850, 880, 910, 940 nm)—enables SWDM transmission that consolidates 100G onto two fibers (duplex) and reaches 150 meters, or supports 400G over eight fibers to 100 meters. This wavelength-division approach reduces fiber count, simplifies trunk design, and preserves pathway capacity for future growth. For integrators planning 100G server uplinks, storage-area-network extensions, or leaf-to-spine connections in Clos topologies, the FWTYL7575LAM038's 38-meter reach covers typical intra-row, cross-aisle, and meet-in-the-middle scenarios without requiring mode-conditioning patches or singlemode crossover.
The 12-fiber count in this trunk aligns with industry-standard cassette breakout ratios—one 12-fiber trunk feeds a single MTP®-12 cassette that breaks out to six duplex LC ports, or two trunks feed a 24-fiber cassette for 12 duplex ports. This modularity simplifies MAC workflows: pull a single lime trunk between racks, plug into a QuickNet cassette enclosure, and gain six 100G-capable duplex links with no field splicing. The 50-micron core and laser-optimized refractive index profile ensure modal bandwidth >4700 MHz·km at 850 nm (OM5 specification), supporting 100-meter 100GBASE-SR4 with headroom for link-loss budget and future transceiver generations.
Small-Diameter Trunk Construction for High-Density Pathways
Traditional approaches to 12-fiber connectivity—bundling six duplex LC patch cords or running individual fibers in protective sleeving—consume significant cable tray and conduit fill. The FWTYL7575LAM038 consolidates all 12 fibers into a single ruggedized trunk jacket with an outside diameter approximately 30 to 40% smaller than equivalent bundled assemblies. This reduction directly translates to increased pathway capacity: a 4-inch-wide ladder rack that would accommodate 18 bundled assemblies can fit 28 to 30 Panduit small-diameter trunks, preserving airflow and simplifying cable management. In under-floor and overhead-tray environments where fill ratios must comply with NFPA 70 (NEC) Article 300 and TIA-569 pathway standards, the space savings allow integrators to add links without expanding infrastructure or violating thermal derating limits.
The lime LSZH jacket provides dual benefits: visual differentiation and safety compliance. In mixed-fiber installations where OM3 (aqua), OM4 (violet/erika), and OM5 (lime) coexist, color-coding eliminates the need to trace cables or consult documentation during troubleshooting—technicians identify fiber type at a glance and select the correct test reference cord. LSZH construction meets low-smoke and halogen-free requirements per IEC 60754-1 and IEC 61034, critical for installations in occupied spaces, international sites, and environments where toxic combustion byproducts present life-safety risks. Unlike PVC jackets that release hydrochloric acid and dense smoke during fire, LSZH compounds limit visible smoke and corrosive gas emissions, protecting both personnel and sensitive electronic equipment.
Factory Termination and QuickNet System Integration
Field termination of multimode fiber—whether fusion splicing or mechanical splice-on connectors—introduces variability in insertion loss, return loss, and end-face geometry. The FWTYL7575LAM038 ships factory-terminated with each fiber cleaved, polished, and tested to meet TIA-568-C.3 performance requirements: maximum insertion loss 0.50 dB, typical 0.35 dB, and return loss ≥20 dB. This factory precision eliminates the need for fusion splicers, polishing fixtures, and end-face inspection microscopes on the job site, reducing deployment time from hours to minutes and ensuring consistent link budgets across all 12 fibers. Every assembly includes test data documenting per-fiber insertion and return loss, enabling integrators to verify performance before installation and maintain audit trails for customer handoff.
QuickNet trunk cable assemblies integrate directly with Panduit's cassette-based distribution architecture. A typical deployment: mount a QuickNet fiber adapter panel in the distribution rack, insert MTP-to-LC cassettes (each cassette breaks one 12-fiber MTP trunk into six duplex LC ports), plug the lime trunk into the rear MTP port, and connect servers or switches to the front LC ports. This modular approach supports incremental scaling—add cassettes and trunks as port demand grows—and simplifies troubleshooting by isolating faults to a single cassette or trunk rather than tracing individual fibers through splice trays. For integrators managing hundreds or thousands of fiber links across multiple data halls, the QuickNet system reduces installation labor, minimizes documentation overhead, and accelerates problem resolution during outages.
Compliance, Interoperability, and Deployment Context
The FWTYL7575LAM038 meets or exceeds ISO/IEC 11801 Class OM5, TIA-568-C.3 Category OM5, IEC 60793-2-10 Type A1a.3, and TIA-492-AAAD specifications for wideband multimode fiber. It complies with TIA-604-5 (FOCIS-5) connector intermateability standards, ensuring reliable connection with any MTP- or MPO-compliant adapter or cassette. RoHS compliance confirms that the assembly contains no lead, mercury, cadmium, hexavalent chromium, or restricted flame retardants, meeting EU and California material-composition mandates for electronic products. For projects requiring third-party verification or agency listings, the LSZH jacket formulation carries IEC flame-test certifications recognized by European EN 50575 CPR (Construction Products Regulation) frameworks.
This 38-meter trunk fits deployments where zone distribution exceeds the 15-meter reach of typical intra-rack trunks but remains within the 100- to 150-meter OM5 channel limits. Common scenarios include cross-aisle spine connections in leaf-spine fabrics, meet-in-the-middle architectures where two 38-meter trunks splice at an intermediate distribution frame to form a 76-meter channel, and storage-area-network links between primary and secondary arrays in adjacent rows. The 12-fiber count supports six bidirectional 100G links or three 400G links (using 8 fibers each with 4 dark spares), aligning with typical ToR (top-of-rack) switch uplink configurations and SAN director port densities. Integrators deploying Cisco Nexus, Arista, Juniper QFX, or Brocade SAN switches will find the FWTYL7575LAM038's length, fiber count, and OM5 performance grade directly compatible with published transceiver reach specifications and structured cabling design guidelines in TIA-942 (data center infrastructure standard).
