Panduit FWTYL7575LNM018 OM5 12F Trunk 18m LSZH

Panduit FWTYL7575LNM018 OM5 12-Fiber QuickNet Trunk Cable Assembly

The Panduit FWTYL7575LNM018 is an 18-meter OM5 trunk cable assembly engineered for high-density data center deployments requiring extended reach and strict LSZH compliance. This 12-fiber trunk uses PanMPO female-to-female connectors with Method B polarity, HD Flex small-diameter construction, and Ultra insertion loss specification. The lime LSZH jacket meets IBC plenum requirements while the 50µm wideband multimode fiber supports 40GBASE-SR4, 100GBASE-SR4, and emerging short-wavelength division multiplexing (SWDM) protocols up to 400G. Designed for QuickNet rapid infrastructure builds, this trunk delivers 30-40% pathway space savings over standard constructions, critical when filling overhead ladder racks or raised-floor conduits in colocation or enterprise facilities.

Key Features

• OM5 wideband multimode fiber (50µm core, 953nm wavelength optimization) supports 40G/100G SR4, 100G BiDi, and 400G SWDM protocols
• 12-fiber count in PanMPO female-to-female configuration (MTP/MPO compatible) with Method B polarity for standard array patching
• 18-meter (59 ft) length covers most intra-data-center horizontal runs without mid-span splice points
• HD Flex small-diameter trunk construction reduces pathway fill by 30-40% versus legacy 12-fiber designs
• Low Smoke Zero Halogen (LSZH) jacket compliant with IBC plenum requirements and European CPR standards
• Ultra insertion loss specification provides link budget margin for 40G/100G optics operating near sensitivity thresholds
• Lime jacket color per TIA-598 OM5 identification standard simplifies inventory and field verification
• QuickNet system integration: factory-terminated, factory-tested, ships ready to install with no field termination
• Meets ISO/IEC 11801, TIA-568-C.3, TIA-604-5 (FOCIS-5), and TIA-492-AAAD fiber geometry standards
• RoHS compliant; backed by Panduit manufacturer warranty

OM5 fiber extends multimode's viability in 40G/100G data center fabrics by supporting short-wavelength division multiplexing (SWDM), which transmits four wavelengths (850/880/910/940 nm) over a single fiber pair. This trunk's 50µm wideband-optimized core meets TIA-492-AAAD geometry specs and delivers the effective modal bandwidth (EMB) required for 100GBASE-SR4 at 100m and emerging 400G SWDM applications at 70-100m reaches. The Ultra insertion loss classification ensures that connector and fiber attenuation stay well below the 1.5 dB budget typical of SR4 and BiDi optics, preserving margin even when patching through multiple interconnects or operating near maximum channel length. For integrators migrating from OM3/OM4 or installing greenfield 100G spines, OM5 provides a future-proof physical layer without requiring immediate 400G optics—existing 40G/100G SR4 transceivers operate on OM5 at their rated distances, and the infrastructure is ready when SWDM or 400G-SR8 modules become cost-effective.

The PanMPO female-to-female connector pair uses Method B polarity: key-up on one end, key-down on the other, with fiber positions mirrored (position 1 to 12, 2 to 11, etc.). This configuration integrates directly with TIA-568 Method B cassette modules and breakout panels, the dominant architecture in enterprise and colocation data centers. Each PanMPO interface is factory-polished to less than 0.25 dB insertion loss and inspected for end-face geometry per IEC 61300-3-35, eliminating the variability and rework common with field-terminated MPO connectors. The 18-meter length is optimized for typical data center row-to-row or end-of-row switch-to-aggregation runs: it spans 59 feet of overhead tray plus vertical drops and patch panel slack without requiring mid-span splice enclosures, reducing both labor and potential failure points. When combined with Panduit's pre-terminated cassettes (sold separately), this trunk enables a complete plug-and-play 40G or 100G structured cabling system that can be installed and tested in a fraction of the time required by fusion-spliced or field-terminated alternatives.

The HD Flex construction uses a reduced-diameter jacket (approximately 5.4 mm OD for 12-fiber) compared to legacy 12-fiber trunks (7-8 mm OD), achieving 30-40% pathway space savings without sacrificing pulling tension or bend radius performance. This is critical in high-density environments where overhead ladder racks or under-floor conduits are shared with power, copper structured cabling, and HVAC ducting. The LSZH outer jacket meets International Building Code (IBC) plenum requirements and European Construction Products Regulation (CPR) Euroclass standards, making it suitable for installation in air-handling spaces, enclosed cable trays, and jurisdictions that mandate halogen-free materials. During a fire event, LSZH materials produce significantly less smoke opacity and zero corrosive halogen gases (chlorine, fluorine), improving egress visibility and reducing damage to adjacent electronic equipment. The lime jacket color follows the TIA-598 standard for OM5 fiber identification (aqua = OM3/OM4, lime = OM5), allowing technicians to visually distinguish fiber types during moves, adds, and changes—a small detail that prevents accidental cross-patching between incompatible media types and simplifies compliance audits. For integrators working under design-build contracts with strict material and testing specifications—LEED data centers, financial trading floors, government SCIFs—this trunk's combination of LSZH compliance, Ultra IL performance, and TIA-568-C.3 certification provides the documentation trail and performance margin required to pass third-party acceptance testing on the first attempt.
