Panduit FWTYL7575KAM091 OM5 12F 91m LSZH Trunk Cable

Panduit FWTYL7575KAM091 OM5 12-Fiber PanMPO Trunk Cable Assembly

The Panduit FWTYL7575KAM091 delivers extended-reach OM5 fiber connectivity for high-density datacenter backbone installations where 91-meter spans and plenum-compliant fire ratings are non-negotiable. This 12-fiber PanMPO-to-PanMPO trunk combines wideband multimode OM5 (50μm) fiber with Low Smoke Zero Halogen jacket construction, HD Flex small-diameter design for 30-40% space savings in congested pathways, and Ultra Insertion Loss rating for margin-critical 40/100/400 Gbps links. Method A polarity and integrated pulling eye simplify deployment across spine-leaf topologies and structured cabling architectures demanding rapid turnaround with zero field termination.

Key Features

• OM5 Wideband Multimode Fiber: 50μm core supports SWDM (Short Wavelength Division Multiplexing) for 40/100/400 Gbps transmission over extended distances, backward-compatible with OM3/OM4 infrastructure
• 12-Fiber PanMPO Female-to-Female Configuration: High-density 12-lane parallel optics interface matches industry-standard MPO footprint while delivering Panduit's enhanced mechanical performance and low insertion loss
• 91-Meter (298.56 ft) Extended Reach: Pre-terminated length addresses cross-floor, cross-aisle, and perimeter-to-core datacenter runs without intermediate splice points
• Low Smoke Zero Halogen (LSZH) Jacket: IEC 60332 plenum-rated construction eliminates corrosive halogen emissions during fire events, meeting European EN 50173 and North American building code requirements for occupied spaces
• HD Flex Transition Small-Diameter Design: 30-40% reduced cross-section compared to legacy 12-fiber trunk cables enables higher fill ratios in cable trays, vertical risers, and overhead ladder rack while maintaining 2.0mm tight-buffered fiber protection
• Method A Polarity: Straight-through pin mapping (transmit lane 1 to receive lane 1) simplifies structured cabling design and eliminates field polarity adapters for duplex breakout applications
• Ultra Insertion Loss Rating: Factory-terminated PanMPO connectors meet TIA-604-5 (FOCIS-5) Grade B maximum 0.35 dB insertion loss per mated pair, preserving link budget for extended-reach 100/400 Gbps Ethernet and 32G/128G Fibre Channel
• Integrated Pulling Eye: Reinforced attachment point on one cable end distributes tensile load across jacket and strength members during installation, preventing fiber strain and connector damage in long conduit pulls
• Lime Jacket Color: High-visibility OM5 identification per TIA-598-D fiber color code standard prevents cross-connection errors during maintenance and upgrades
• QuickNet Platform Integration: Compatible with Panduit's modular QuickNet cassettes, panels, and enclosures for tool-free moves/adds/changes and pre-tested end-to-end channel certification

The FWTYL7575KAM091's OM5 fiber specification (TIA-492-AAAD, IEC 60793-2-10 Type A1a.3) extends effective modal bandwidth to 4700 MHz·km at 953 nm SWDM wavelength, enabling 100 Gbps transmission over 150 meters or 400 Gbps over 100 meters using BiDi or parallel optics transceivers—double the reach of OM4 at equivalent data rates. This extended link budget accommodates datacenter topologies where equipment-row aggregation switches sit more than 70 meters from core routers, eliminating costly intermediate fiber distribution frames. The wideband 840-953 nm operating window future-proofs infrastructure for emerging SWDM4 and SWDM8 transceiver technologies that multiplex four or eight wavelengths over a single fiber pair, delivering 400 Gbps or 800 Gbps without re-cabling.

PanMPO connectors use precision-molded ferrules with 12 physical contact fiber positions on 250μm pitch, spring-loaded to maintain <0.05 dB variation across thermal cycles and vibration exposure. Method A polarity configuration maps transmit lane 1 (position 1, row 1) on the near end to receive lane 1 (position 1, row 1) on the far end, implementing the straight-through pin assignment required by IEEE 802.3ba/cd/ck Ethernet and ANSI T11 Fibre Channel standards when connecting switch QSFP/OSFP ports to breakout cassettes or another switch in a spine-leaf fabric. This eliminates the Type B crossover trunks and polarity-flip adapters often needed with Type A or Type C connector systems, reducing bill-of-materials complexity and eliminating a common source of Day 2 troubleshooting calls. The HD Flex cable construction uses 2.0mm tight-buffered fibers in a flexible central bundle surrounded by aramid yarn strength members and a reduced-diameter LSZH outer jacket, achieving a 4.6mm overall diameter versus 7.2mm for traditional fanout-style 12-fiber assemblies. In a 4-inch-wide by 4-inch-tall horizontal cable tray, this reduces tray fill from 42% to 26% for a 48-strand fiber deployment (four 12-fiber trunks), leaving adequate service loop and bend radius clearance while meeting NEC Chapter 8 and TIA-568 installation standards. The pulling eye termination integrates a stainless steel thimble crimped to the cable's aramid strength members and jacket, rated for 100 lbf (445 N) pulling tension—sufficient for 300-foot conduit runs with two 90-degree bends when paired with approved cable lubricant and intermediate pull boxes.

LSZH jacket formulation substitutes aluminum trihydrate and magnesium hydroxide flame retardants for PVC and halogenated compounds, producing water vapor and inert metal oxides instead of hydrochloric acid and dioxins during combustion. This meets IEC 60332-1 and IEC 60754 low-halogen emission limits (<0.5% halogen content by weight) required for European telecommunications rooms, as well as UL 94 V-0 vertical flame test and plenum (OFNP) or riser (OFNR) ratings under NEC Article 770. For occupied datacenter spaces, mixed-use telecom closets, or facilities housing sensitive electronics, LSZH construction reduces equipment corrosion risk and improves egress safety during fire events compared to standard PVC-jacketed cables. The 91-meter factory-specified length addresses the 70-90 meter range common in large colocation facilities and enterprise datacenters with separate hot-aisle/cold-aisle equipment rows, perimeter meet-me rooms, and centralized core switching infrastructure. Pre-termination with factory-tested insertion loss and return loss performance eliminates field fusion splicing labor (typically $15-25 per fiber pair) and the risk of contamination-induced link failures that plague field-installed connectors in production environments.

This assembly ships with test reports certifying compliance to ISO/IEC 11801 generic cabling, TIA/EIA-568-C.3 optical fiber cabling components, and TIA-604-5 (FOCIS-5) MPO connector intermateability standards, with insertion loss guaranteed ≤0.35 dB per mated connector pair and return loss ≥20 dB across all 12 fibers. RoHS compliance (lead-free, mercury-free) meets EU Directive 2011/65/EU for equipment sold into European markets. The lime-green jacket color and "OM5" printed legend provide instant visual identification during MAC (moves, adds, changes) work, preventing accidental cross-connection to OM3 (aqua) or OM4 (magenta) infrastructure that would limit link performance. For datacenters migrating from 10/40 Gbps OM3 backbones to 100/400 Gbps OM5 spine-leaf architectures, or new builds standardizing on wideband multimode for 5-10 year technology refresh cycles, the FWTYL7575KAM091 delivers the extended reach, high fiber density, and fire-safe jacket construction required for Tier III/IV facility compliance and insurance underwriter approval—without the cost and 100+ meter distance limitations of single-mode fiber deployments.
