Panduit FWTYL7575KAM012 OM5 12F Trunk LSZH 12m

Panduit FWTYL7575KAM012 QuickNet OM5 12-Fiber Trunk Cable Assembly

The Panduit FWTYL7575KAM012 is a 12-meter OM5 SigCore trunk cable assembly engineered for high-density data center deployments where rack space, fire rating, and future bandwidth headroom are critical constraints. This PanMPO-to-PanMPO trunk features ultra-insertion-loss performance and LSZH jacketing that meets IBC and NEC plenum-equivalent fire standards for enclosed cable pathways. The HD Flex construction delivers 30 to 40 percent diameter reduction compared to legacy 12-fiber trunks, freeing conduit fill and cable-tray capacity in fully loaded rows. Method A polarity simplifies cross-connect design, and the integrated pulling eye on one end accelerates installation through overhead ladder rack or underfloor grids without custom breakout kits.

Key Features

• OM5 wideband multimode fiber — 50 µm core supports 100GBASE-SR4 to 150 m and 400GBASE-SR8 short-wave optics, extending reach beyond OM4 by 30-50 m per link
• Ultra insertion loss specification — tighter manufacturing tolerances reduce link budget margin erosion on multi-trunk spine paths
• LSZH outer jacket — low-smoke zero-halogen compound meets IEC 60332-3-24 vertical flame test and reduces toxic gas emission in fire events, satisfying most international building codes for occupied-space cable routing
• 30-40% space savings — small-diameter SigCore construction fits more trunks per U-space panel cutout and reduces bend-radius footprint behind patch fields
• PanMPO female to PanMPO female connectors — mated-pair keying prevents insertion errors; both ends accept industry-standard MPO pin adapters or Panduit cassette modules
• Method A polarity — TIA-568-C.0 Annex B compliant; transmit fibers on one end map to receive fibers on the far end without in-line polarity flips
• Integrated pulling eye — factory-installed on one connector simplifies horizontal and vertical cable pulls through J-hooks, cable trays, or conduit without field-terminating breakout legs
• 12-fiber count — supports one 40G/100G QSFP port or future 400G-SR8 transceiver with fiber to spare for redundancy or breakout to 4×10G lanes
• 12-meter length — pre-terminated to eliminate field splicing and fusion labor; suits typical row-to-EOR (End of Row) distances in modular data halls
• Lime green jacket — OM5 color standard per TIA-598-D Annex F, preventing accidental cross-patching with OM3/OM4 trunks during maintenance

OM5 fiber extends the installed base life of your physical layer by delivering dual-wavelength transmission (850 nm and 950 nm) that enables short-wave division multiplexing (SWDM). Where OM4 trunks top out at 100 m for 100GBASE-SR4, this assembly reaches 150 m, buying additional flexibility when EOR switch placement is constrained by power or cooling. The wideband specification also future-proofs the link for 200G and 400G optics that rely on four or eight parallel lanes — you avoid a complete re-pull when you refresh to next-generation BiDi or SWDM transceivers. Panduit's ultra-insertion-loss grade tightens the connector endface geometry and ferrule concentricity beyond the standard 0.35 dB maximum, leaving more link budget for additional interconnects or longer patch cords. In a typical two-tier leaf-spine fabric with three mated pairs per path (server → ToR cassette → trunk → spine cassette), every 0.1 dB saved on the trunk prevents margin calls that force optics substitution or topology changes mid-deployment. The SigCore microcable construction wraps twelve 50 µm fibers in a reduced-diameter sheath that measures roughly 3.0 mm OD — about two-thirds the bulk of traditional round 12-fiber assemblies. That reduction translates directly into usable rack space: a 1U breakout panel that previously accepted eight legacy trunks can now route twelve or more SigCore trunks through the same finger-duct opening, deferring the need for larger enclosures or secondary patch fields. Bend radius also shrinks, so you can dress trunks tighter around vertical managers and back-of-rack cable arms without violating the manufacturer's minimum bend spec or risking kink-induced attenuation.

The LSZH jacket is mandatory for installations where fire code restricts PVC or plenum-rated materials — common in European and Asia-Pacific markets, and increasingly required in North American healthcare, education, and government facilities. Unlike plenum-rated cables that rely on fluoropolymer formulations, LSZH compounds produce minimal smoke opacity and halogen acid gas when exposed to flame, reducing life-safety risk during evacuation and limiting corrosive damage to adjacent IT equipment. This assembly meets IEC 60332-3-24 Category C vertical flame propagation and IEC 61034-2 smoke density tests, satisfying the fire-performance section of ISO/IEC 11801 for permanent links in occupied spaces. The lime green outer jacket follows TIA-598-D color conventions, providing instant visual confirmation that the trunk is OM5 — critical when your patch field mixes OM3 aqua, OM4 magenta, and OM5 lime trunks across the same horizontal manager. Method A polarity uses a straight-through fiber mapping on both connectors (position 1 → position 1, position 12 → position 12), so the transmit lane at one end arrives at the corresponding receive lane on the far end without requiring a Type-B crossover trunk or polarity-reversing adapter. This simplifies documentation and troubleshooting: every trunk behaves identically, and you can stock a single SKU for all inter-tier connections in a Clos or leaf-spine design. Both PanMPO connectors are female, meaning the pins reside in the mating adapter or cassette module rather than in the trunk itself — the female form factor protects the exposed ferrule endfaces during storage and handling, reducing the risk of scratches or contamination that would degrade insertion loss. The factory-installed pulling eye on one connector end provides a secure attachment point for fish tape or pull cord, letting you route the trunk through overhead J-hook runs, underfloor conduit, or vertical riser shafts without fashioning a field breakout or taping the connector body. For typical row-to-EOR or server-to-aggregation pulls in modular data centers, the 12-meter length covers most horizontal distances while keeping the trunk short enough to coil neatly behind patch panels, minimizing service loop clutter. Each trunk is individually tested for insertion loss, return loss, and polarity before leaving the factory, and ships with test data traceable to the serialized connector tags — eliminating the field certification step that would otherwise require an MPO reference-grade test set and adding labor to your deployment schedule.

This trunk assembly meets or exceeds ISO/IEC 11801 Ed. 2.2, TIA-568-C.3, TIA-604-5 (FOCIS-5 endface geometry), and TIA-492-AAAD (OM5 fiber performance), ensuring compliance with industry standards for commercial-building structured cabling. It is RoHS-compliant and suitable for projects requiring low-halogen materials under green-building certifications or government procurement rules. Deploy the FWTYL7575KAM012 when you need a pre-terminated, factory-tested OM5 trunk that installs faster than field-fusion kits, occupies less space than traditional round cable, and satisfies fire-safety regulations for enclosed data-center pathways — delivering a physical layer that supports today's 40G/100G optics and scales to 200G/400G without a forklift upgrade.
