Panduit FWTYL7575LAM070 12-Fiber OM5 70-Meter Trunk Cable Assembly
The Panduit FWTYL7575LAM070 is a 12-fiber OM5 wideband multimode trunk cable assembly designed for high-density data center deployments requiring extended reach and future-proof bandwidth. This 70-meter (230-foot) pre-terminated QuickNet assembly delivers plug-and-play connectivity for 40G, 100G, and emerging 400G Ethernet applications, eliminating field termination labor while maintaining full TIA-568-C.3 and ISO/IEC 11801 compliance. The LSZH jacket and small-diameter trunk construction address the two critical constraints in modern raised-floor environments: fire safety in enclosed pathways and pathway fill capacity in congested overhead cable trays.
Key Features
- 12-fiber OM5 wideband multimode construction supports short-wave division multiplexing (SWDM) for 40GBASE-SR4, 100GBASE-SR4, and future 400GBASE-SR8 applications over extended reach
- 70-meter overall length enables cross-floor horizontal links, perimeter-to-core runs, and intra-building connections in large enterprise or colocation facilities
- QuickNet pre-terminated design eliminates field splicing and fusion work, reducing installation time by 60-80% compared to bulk fiber pulls
- LSZH (low smoke zero halogen) jacket complies with IEC 60332-3 and NFPA 90A for plenum and riser installations in occupied spaces
- Small-diameter trunk cable design uses 30-40% less pathway space than traditional tight-buffered assemblies, critical for high-density environments approaching TIA-569 40% fill limits
- Lime jacket color provides instant OM5 identification per TIA-598 color coding standards, preventing cross-connection errors during moves/adds/changes
- Factory-terminated and tested MTP/MPO connectors ensure insertion loss ≤0.35 dB per mated pair and return loss ≥-20 dB across all 12 fibers
- 50-micron core diameter with laser-optimized gradient-index profile supports 28 Gbps per lane for emerging PAM4 and coherent optics applications
- RoHS-compliant materials meet EU Directive 2011/65/EU and California Proposition 65 requirements for restricted substances
OM5 wideband multimode fiber extends the operational wavelength range from OM3/OM4's single 850nm window to a full 850-950nm band, enabling short-wave division multiplexing (SWDM) over a single fiber pair. This advancement allows 40GBASE-SR4 and 100GBASE-SR4 transceivers to transmit four wavelengths (850, 880, 910, 940nm) simultaneously, quadrupling effective bandwidth without additional fiber pairs. For 12-fiber trunk cables like the FWTYL7575LAM070, this translates to support for three independent 40G links or a single 100G link with redundancy, using the same physical infrastructure that would otherwise require 48 fibers in an OM3 deployment. The 70-meter length falls within OM5's 150-meter reach specification for 40G/100G SWDM applications, making this assembly suitable for horizontal cross-connects, equipment distribution area (EDA) to main distribution area (MDA) links, or perimeter-to-core runs in facilities up to 75,000 square feet. The fiber's laser-optimized gradient-index profile maintains effective modal bandwidth (EMB) of 3500 MHz·km at 850nm and 1850 MHz·km at 950nm, ensuring margin for 28 Gbps PAM4 signaling used in emerging 400GBASE-SR8 and 800G applications. OM5's lime jacket color—standardized in TIA-598-D and ISO/IEC 14763-2—provides instant visual differentiation from aqua OM3 and erika violet OM4, critical during cutovers when multiple fiber generations coexist in the same pathway.
Data center deployments face two dominant infrastructure constraints: pathway capacity and deployment velocity. The FWTYL7575LAM070 addresses both through its small-diameter trunk construction and factory pre-termination. Traditional 12-fiber tight-buffered assemblies typically measure 6-8mm outer diameter; Panduit's QuickNet trunk design reduces this to approximately 4.5-5.5mm by using 900-micron buffered fibers in a stranded loose-tube configuration rather than individual 3mm tight-buffered legs. This 30-40% diameter reduction translates directly to cross-sectional area savings of 50-65%, allowing installers to fit nearly double the fiber count in a 4-inch cable tray or overhead J-hook pathway before hitting TIA-569-D's 40% fill ratio limit. In high-density top-of-rack (ToR) switch deployments—where each 48-port switch may require four to six 12-fiber uplinks to spine switches—this space efficiency determines whether a facility can scale to target port density without expensive pathway remediation. The pre-terminated MTP/MPO connectors eliminate the 45-60 minutes per connector typically required for field fusion splicing, and remove the need for fusion splicers, cleavers, and OTDR test equipment at the install site. For a 24-rack deployment requiring 96 fiber links (768 fibers), pre-terminated trunks reduce installation labor from approximately 115 hours of fusion work to under 20 hours of plug-and-test verification—a labor savings that typically offsets the assembly's premium over bulk fiber within the first eight trunks installed. The 70-meter length accommodates the longest typical horizontal runs in enterprise data centers: a 60-meter maximum horizontal distance per TIA-942-B, plus 8-10 meters of vertical riser slack and patch panel service loops.
The LSZH jacket formulation meets IEC 60332-3 Category C vertical flame propagation requirements and IEC 61034 smoke density limits (light transmittance ≥60% after 40 minutes), qualifying the cable for installation in air-handling plenums, vertical risers, and behind-the-wall pathways per NFPA 90A and NEC Article 770. Unlike PVC-jacketed assemblies that release hydrochloric acid and dense black smoke during combustion, LSZH cables emit primarily water vapor and carbon dioxide, reducing toxic gas exposure and maintaining visibility during facility evacuation—critical in colocation and multi-tenant environments where fire events affect occupants beyond the data center operator's direct control. All 12 fibers meet TIA-492-AAAD specifications for OM5 attenuation (≤2.4 dB/km at 850nm, ≤2.0 dB/km at 950nm) and geometry (50±3 micron core, 125±1 micron cladding), with factory test results serialized to the assembly's pull-tab label for as-built documentation. This assembly is optimized for leaf-spine architectures in enterprise private clouds, storage area network (SAN) fabrics requiring deterministic latency under 10 microseconds, and hyperscale colocation facilities deploying 100G access layers with 400G spine uplinks.
