Panduit FWTYL7575LAM056 QuickNet 12-Fiber OM5 Trunk Cable Assembly
The Panduit FWTYL7575LAM056 is a 12-fiber OM5 wideband multimode trunk cable assembly engineered for high-density data center backbone installations where extended reach and rapid deployment are critical. Spanning 56 meters (183.73 feet), this pre-terminated QuickNet assembly eliminates field termination labor while delivering the bandwidth headroom needed for 40G/100G/400G short-wave wavelength division multiplexing (SWDM) architectures. Its small-diameter LSZH-rated construction consumes 30 to 40 percent less pathway space than conventional trunk cables, directly addressing congestion in overhead cable trays, under-floor voids, and vertical riser conduits. Lime-jacketed for instant OM5 identification, this assembly is factory-tested to TIA-568-C.3 and ISO/IEC 11801 standards, arriving ready to lock into your MDA-to-HDA or backbone-to-horizontal cross-connect infrastructure.
Key Features
- OM5 wideband multimode fiber supports SWDM 100GBASE-SR4 to 150m and 400GBASE-SR4.2 to 100m, future-proofing beyond OM4's single-wavelength limits
- 12-fiber count in a reduced-diameter trunk configuration optimizes bundle density for backbone and inter-building links without sacrificing port capacity
- LSZH (Low Smoke Zero Halogen) flammability rating meets stringent data center and European building codes, minimizing toxic emission risk during fire events
- Pre-terminated and factory-tested to insertion loss and return loss specifications per TIA-604-5 (FOCIS-5), eliminating field splicing delays and human error
- Lime jacket color provides instant visual compliance verification in multi-generation fiber plants mixing OM3, OM4, and OM5 infrastructure
- 56-meter length addresses typical intra-building distances between main distribution areas and intermediate cross-connects or equipment rows
- Small-diameter construction reclaims 30-40% pathway fill capacity, deferring costly cable tray expansions in retrofit scenarios
- RoHS compliant and meets TIA-492-AAAD and IEC 60793-2-10 type A1a.3 fiber performance standards
OM5 fiber represents the current apex of 50-micron multimode technology, introducing wideband laser optimization across the 850nm to 953nm spectrum. Where OM4 relies on a single 850nm wavelength, OM5's extended modal bandwidth supports short-wave wavelength division multiplexing—four or more discrete laser channels riding the same fiber pair. This matters in practice: a 100GBASE-SR4 link over OM4 reaches 100 meters using four 25G lanes at 850nm; over OM5 with SWDM optics, that same 100G signal can travel 150 meters, and 400GBASE-SR4.2 extends to 100 meters using eight 50G lanes across four wavelengths per fiber. For data center operators planning 400G spine fabrics or future 800G migrations, OM5 trunk assemblies like the FWTYL7575LAM056 buy an additional 50 meters of reach before stepping up to single-mode infrastructure or active repeaters. The 12-fiber count aligns with polarity Method B and Method C trunk-to-harness breakout strategies: six duplex channels for parallel optics, or twelve simplex strands for bidirectional transceiver architectures. Factory-applied connectors—whether MPO/MTP base connectors on each end or fanout harnesses (verify configuration with distributor)—arrive with insertion loss test reports traceable to NIST standards, a requirement for Uptime Institute Tier III/IV certification paths where every dB of margin counts against BER thresholds.
High-density data centers face a relentless space crunch: 1RU servers with four or six 100G ports, top-of-rack switches demanding 32 to 64 fiber connections, and overhead ladder racks sagging under the cumulative weight of legacy CAT6A copper and first-generation OM3 trunk bundles. Panduit's small-diameter trunk cable design directly attacks this congestion. By thinning the jacket, tightening the buffer tube lay, and optimizing the strength member profile, the FWTYL7575LAM056 achieves a bend radius and cross-sectional area 30 to 40 percent smaller than standard 12-fiber assemblies built to older geometric tolerances. In practice, this means fitting sixteen small-diameter trunks in the same 4-inch ladder rack that previously held only ten conventional assemblies—equivalent to adding 72 fibers of capacity without installing new pathways. The 56-meter length bridges common data center topologies: main distribution area (MDA) on the loading dock to horizontal distribution area (HDA) at mid-building; equipment distribution area (EDA) in a server row to an intermediate cross-connect in a meet-me room; or building entrance facility to a secure colocation cage two floors up. Pre-termination eliminates the fusion splicing crew, the overnight maintenance window for testing, and the risk of a technician damaging $60,000 worth of optics because a connector endface has a 2-micron scratch. Pull the assembly, snap it into your fiber enclosure's MPO adapter panel, verify continuity with an OTDR or visual fault locator, and your 12-strand backbone is live. For integrators juggling eight-week equipment lead times and three-day installation cutover windows, that simplicity is the difference between a smooth commissioning and penalty clauses.
The FWTYL7575LAM056 carries full compliance with TIA-568-C.3 (premises fiber cabling), ISO/IEC 11801 (international structured cabling), and TIA-492-AAAD (OM5 fiber specifications), ensuring insertion loss below 0.35 dB per mating pair and return loss exceeding 20 dB across all twelve fibers. LSZH jacketing meets IEC 60332-1 flame propagation and IEC 61034 smoke density limits, a mandatory checkbox for hyperscale facilities built to European EN 50173 standards and increasingly adopted by U.S. colocation providers seeking insurance-rate reductions. For systems integrators designing Tier III/IV data halls with N+1 or 2N redundancy, this trunk assembly slots into dual-path architectures where a single fiber failure cannot orphan a compute pod: route one 12-fiber trunk through the east cable tray to EDA-A and a second through the west tray to EDA-B, and your leaf-spine fabric survives a severed bundle during a careless forklift incident. The lime jacket is not decorative—it's a safety interlock, preventing a technician from accidentally patching an OM5 trunk into an OM3 infrastructure tier where the installed-base optics lack the laser tuning to exploit the wideband advantage. If your fiber plant roadmap includes a staged OM3-to-OM5 migration, color-coding each generation prevents the expensive mistake of running 400G SWDM optics over a legacy 10G-optimized link.
