Panduit FWTYL7575KNM036 OM5 12F Trunk 36m LSZH

Panduit FWTYL7575KNM036 QuickNet OM5 SigCore 12-Fiber Trunk Cable Assembly

The Panduit FWTYL7575KNM036 is a 36-meter (118 ft) OM5 SigCore trunk cable assembly engineered for high-density data center deployments requiring extended reach and future-proof bandwidth. This factory-terminated 12-fiber trunk features PanMPO female connectors on both ends, HD Flex reduced-diameter construction, and Low Smoke Zero Halogen (LSZH) jacketing. OM5 fiber supports short-wave wavelength division multiplexing (SWDM) for 100GBASE-SR4 and 400GBASE-SR8 applications over extended distances, while the HD Flex design delivers 30–40% space savings in congested pathways—critical when you're routing dozens of trunks through 4-inch vertical managers or over-subscribed cable trays in spine-leaf topologies.

Key Features

• OM5 SigCore Fiber: Wideband multimode optimized for SWDM, extending 100G reach to 150m and enabling 400G over 100m—double the distance of OM4 in many configurations
• PanMPO Connectors: Panduit's enhanced MPO design with improved ferrule geometry and alignment for ultra-low insertion loss (<0.35 dB typical) and better mechanical durability than generic MPO
• HD Flex Construction: Reduced outer diameter (typically 30–40% smaller than standard round cable) enables higher fill ratios in pathways and reduces installation labor in congested racks
• Method A Polarity: Standard TIA-568 polarity for straightforward duplex-to-parallel fiber conversion using Type A breakout modules or cassettes
• LSZH Jacket: Low Smoke Zero Halogen rating for plenum and riser installations in occupied spaces, meeting international fire safety standards without PVC toxicity
• Factory Terminated: All 12 fibers pre-polished and tested to Ultra Insertion Loss specifications, eliminating field termination errors and delivering guaranteed performance out of the box
• 36-Meter Length: Purpose-built for inter-rack and intra-row connections in medium-to-large data centers, spine-to-leaf switch runs, or SAN fabric links where 15m is too short and 50m+ introduces unnecessary slack
• Lime Green Jacket: High-visibility OM5 color coding per TIA-598 for instant identification during adds/moves/changes and troubleshooting

OM5 for Next-Generation Data Centers: OM5 fiber (ISO/IEC 11801 designation) was introduced specifically to support short-wave wavelength division multiplexing (SWDM), a technique that transmits four wavelengths (850, 880, 910, 940 nm) over a single fiber pair. This quadruples effective bandwidth without requiring additional fibers—critical when you're migrating from 100G to 400G and physical port density on switches is maxed out. While OM4 supports 100GBASE-SR4 to 100 meters, OM5 extends that to 150 meters and enables 400GBASE-SR8 over 100 meters (vs. 70m on OM4). For integrators planning 3–5 year infrastructure lifecycles, OM5 provides headroom for bandwidth upgrades without re-cabling. The FWTYL7575KNM036's 36-meter length slots perfectly into typical row-to-aggregation distances in modern hyperscale or colocation facilities, where top-of-rack switches connect to end-of-row or middle-of-row distribution switches. Panduit's SigCore branding denotes fiber that meets OM5's 953 nm effective modal bandwidth (EMB) requirement—this isn't re-labeled OM4; it's tested and certified for SWDM chromatic performance.

PanMPO Connector Advantage: Generic MPO connectors (also called MTP, though that's a US Conec trademark) are commodity parts with wide manufacturing tolerance. Panduit's PanMPO design tightens ferrule endface geometry, pin retention force, and housing alignment to reduce insertion loss variability. On a 12-fiber trunk, the difference between 0.5 dB and 0.3 dB per connector matters—it's 0.4 dB of total link budget reclaimed, enough to extend reach by 10–15% or accommodate an additional mated pair (cassette or patch panel) without exceeding IEEE 802.3's loss budget. The FWTYL7775KNM036 is factory-tested to Ultra Insertion Loss specs, meaning every connector is interferometrically inspected and endface-polished to <0.35 dB typical. This matters in 100G/400G SR optics, which have tighter receiver sensitivity than 10G—link budget margin that evaporates with dirty or poorly polished connectors can cause BER spikes under load. PanMPO's female-to-female configuration is standard for backbone trunks; you'll use male PanMPO-to-LC or PanMPO-to-duplex SC breakout modules on each end, or terminate into PanMPO cassettes (1U or 2U) for quick cross-connects. Method A polarity is TIA-568-compliant: flip the cable (key-up to key-down) and Fiber 1 Tx on one end connects to Fiber 1 Rx on the other—no guesswork, no polarity testers needed during commissioning.

HD Flex Design for Congested Pathways: Traditional round 12-fiber trunk cables range from 6–8 mm OD; HD Flex (high-density flexible) designs use a flat or ribbon-style construction that reduces cross-sectional area by 30–40%. In practice, this means you can route 60–80 trunks through a 4-inch-wide vertical manager that would only handle 40–50 round cables. The benefit compounds in over/under cable trays between rows, where every millimeter of vertical clearance matters when you're trying to maintain 1U of overhead for airflow. HD Flex cables also exhibit lower bend stress—the flat profile distributes tensile load across the width rather than concentrating it on the outer fibers, reducing kink risk during installation. Panduit rates this cable for 20x diameter minimum bend radius (typical ~10 cm), which is achievable in tight 90-degree turns at rack corners without exceeding macrobend loss thresholds. For integrators running 40–100 trunks per row in leaf-spine fabrics, the space savings translate directly into faster installation (less pathway congestion, fewer tie-wraps) and better long-term maintenance access. The lime green LSZH jacket is also sequential-footage marked, so you can verify cable length and cut points without unspooling the entire assembly.

LSZH and Compliance: Low Smoke Zero Halogen jacketing is mandatory in many international data centers (especially Europe and Asia-Pacific) and increasingly specified in U.S. hyperscale facilities where fire codes prioritize occupied-space safety. LSZH produces <5% hydrogen chloride and <0.5% halogen acid gas under combustion—orders of magnitude lower than PVC—reducing corrosive smoke damage to adjacent servers and minimizing respiratory hazards during evacuation. The FWTYL7575KNM036 meets IEC 60332-1 (flame propagation), IEC 61034 (smoke density), and IEC 60754 (halogen content), satisfying NEC Article 770 plenum requirements when installed in air-handling spaces. It's also RoHS-compliant (lead-free, no restricted substances) and tested to TIA-568-C.3 for multimode connector performance, TIA-604-5 (FOCIS-5) for MPO physical dimensions, and ISO/IEC 11801 for OM5 modal bandwidth. The 36-meter length is ideal for installations where 15-meter pre-terminated jumpers are too short (forcing mid-run splicing or cassette-to-cassette patching, both of which add loss and failure points) but 50-meter or 100-meter assemblies introduce excessive service loops that congest pathways and complicate MAC work. Use this trunk for spine-to-leaf runs in rows up to ~25 meters apart (plus vertical rise and horizontal dress), SAN director-to-storage array links in medium-sized machine rooms, or backbone connections between communications rooms on the same floor where structured cabling standards call for permanent trunk links rather than field-installable patch cords.
