Panduit FWTYL7575LAM042 QuickNet OM5 12-Fiber Trunk Cable Assembly
The Panduit FWTYL7575LAM042 is a factory-terminated 12-fiber OM5 trunk assembly designed for high-density data center backbone installations where extended 100G/400G reach and reduced pathway congestion are critical. This 42-meter (137.8 ft) assembly terminates with PanMPO female connectors on both ends, uses HD Flex low-profile cable construction to reduce bundle diameter by 30-40% compared to standard trunks, and ships with a factory-installed pulling eye for direct pathway deployment. The lime-green LSZH jacket meets plenum-alternative smoke/toxicity requirements for international installations and provides instant OM5 visual identification in mixed-generation fiber plants.
Key Features
- OM5 wide-band multimode fiber supports 100GBASE-SR4 to 150m and 400GBASE-SR8 to 100m over duplex 850/950nm transmission
- PanMPO female-to-female HD connectivity with Method B polarity and ultra-low insertion loss for 12-fiber parallel optics breakout
- HD Flex cable construction reduces trunk OD by 35% — critical for 40%+ pathway fill in vertical spine risers and horizontal cable trays
- Factory pulling eye on one end eliminates field prep for direct innerduct or conduit deployment up to 42m pull length
- Low Smoke Zero Halogen (LSZH) jacket compliant with IEC 60332-3-24 for enclosed spaces and international building codes
- Lime-green jacket matches TIA-598-D OM5 color code for instant fiber-type identification during MACs and troubleshooting
- Factory-terminated and tested to TIA-604-5 FOCIS-5 geometry and insertion loss limits — eliminates field termination labor and test failures
- 12-fiber count supports single 100G transceiver breakout or dual 40G links via MTP-to-LC fanout cassettes in EOR/MOR architectures
This trunk assembly uses Panduit's SigCore OM5 fiber, which extends wide-band multimode (WBMMF) performance across both 850nm VCSEL and 950nm shortwave wavelengths. OM5's dual-window optimization enables short-wave wavelength division multiplexing (SWDM) for 100G and 400G Ethernet over fewer fibers than OM3/OM4 — a 100GBASE-SR4 link that requires 8 fibers (4 Tx + 4 Rx) on OM3 can run over 2 fibers using SWDM transceivers on OM5. For integrators planning 400G spine upgrades, OM5 supports 400GBASE-SR8 to 100 meters, compared to 70m on OM4, without requiring single-mode fiber replacement. The assembly's ultra-low insertion loss spec (typically <0.35 dB per connector) preserves link budget for high-port-count breakout topologies where multiple MTP adapter interfaces consume budget before reaching the transceiver. Each PanMPO connector uses Panduit's pinless ferrule design to eliminate endface damage during insertion and features a metal housing with push-pull latch for secure mating in high-vibration rack environments. Method B polarity configuration (key-up to key-down) allows direct transceiver-to-transceiver connection when used with Method B fanout cassettes, eliminating the crossover trunk requirements of Method A and reducing deployment errors in large-scale rollouts.
The HD Flex cable construction addresses the #1 constraint in hyperscale data center deployments: pathway congestion. Standard 12-fiber OM4 trunks typically measure 6.5–7.5mm OD; this assembly's HD Flex design reduces OD to approximately 4.8mm through tight-buffered 200µm fiber and optimized jacket extrusion. In a 4-inch communications pathway filled to TIA-568 40% max fill ratio, this diameter reduction allows you to deploy 62 HD Flex trunks versus 42 standard trunks — a 48% capacity increase in the same conduit. For vertical riser installations between floor distribution areas, the reduced weight and flexibility of HD Flex cable also lowers pulling tension and J-hook sag compared to distribution-style trunk cables. The factory-installed pulling eye on one end simplifies direct innerduct pulls: attach your pull rope, lubricate the pathway, and deploy the full 42-meter length without mid-span splice points or field-terminated breakout legs. The opposite end terminates flush for immediate patch panel or transceiver connection. Installers should note that PanMPO connectors require MTP-compatible adapters (not standard LC or SC); Panduit offers rack-mount MTP cassettes (such as the FAP series) that accept this trunk on the rear MTP port and break out to 12 duplex LC ports on the front for transceiver connection.
The LSZH jacket meets IEC 60332-3-24 Category C vertical flame spread and IEC 61034-2 light transmittance (smoke density) requirements, making this assembly suitable for below-raised-floor and above-ceiling installations in international markets where PVC is restricted. LSZH construction produces <0.5% hydrogen chloride and other corrosive halogens during combustion, protecting sensitive IT equipment in the same fire zone. The lime-green jacket matches TIA-598-D Appendix A OM5 color assignment, ensuring that installers can visually distinguish OM5 trunks from aqua OM3, erika violet OM4, and yellow single-mode cables during maintenance. This assembly is RoHS-compliant for EU installations and meets TIA-568-C.3 and ISO/IEC 11801 Edition 2.2 performance specs for Category OF-500 (OM5) cabling. The fiber itself complies with TIA-492-AAAD and IEC 60793-2-10 Type A1a.3 physical and transmission specifications, guaranteeing <3.0 dB/km attenuation at 850nm and effective modal bandwidth (EMBc) of 4700 MHz·km, which directly translates to the 150m 100GBASE-SR4 reach. Each trunk ships as a single unit with protective dust caps on both MTP connectors and includes a serialized label for as-built documentation and OTDR testing records.
