Panduit FW2RLU1U1NNM004 OM5 LC Uniboot Patch Cord 4m

Panduit FW2RLU1U1NNM004 Opti-Core™ OM5 LC Duplex Uniboot Fiber Patch Cord

The Panduit FW2RLU1U1NNM004 delivers OM5 multimode fiber performance in a space-optimized 2mm uniboot form factor designed for high-density datacenter and enterprise backbone deployments. This 4-meter patch cord uses ultra-low insertion loss LC duplex uniboot connectors with UPC polish on both ends, supporting 40GBASE-SR4, 100GBASE-SR4, and emerging short-wave wavelength division multiplexing (SWDM) applications up to 100 meters. The LSZH jacket meets IEC 60332-1-2 flammability requirements for enclosed IT spaces, equipment rooms, and above-ceiling pathways where PVC combustion byproducts create unacceptable risk. Panduit's Opti-Core construction pairs 50μm OM5 fiber with lime green outer jacket for instant visual identification in mixed-mode installations, while the 2mm reduced-diameter cable body allows 40-50% higher port density compared to legacy 3mm duplex cords in congested patch panels and switch fabrics.

Key Features

• OM5 50μm multimode fiber supports 40G/100G over 100m and SWDM protocols for future bandwidth scaling
• LC duplex uniboot connectors reduce footprint by 50% vs. traditional duplex LC; tool-free polarity reversal without re-termination
• Ultra-low insertion loss specification maintains <0.15dB typical loss for consistent link budgets in multi-hop topologies
• 2mm cable diameter increases usable rack density in 1U panels and enables tighter bend radius in congested pathways
• LSZH jacket rated IEC 60332-1-2 for plenum-equivalent safety in datacenters and telecommunications rooms
• Lime green color coding per TIA-598-D OM5 standard prevents cross-connection errors during MACs

The uniboot design consolidates both fibers into a single compact LC connector housing, cutting the physical footprint in half compared to traditional duplex LC patch cords. This matters in 1U fiber panels where 96-port configurations leave minimal finger room—uniboot connectors maintain full port population without blocking adjacent ports or forcing installers to skip positions. The integrated pull-tab mechanism allows field polarity reversal in under 10 seconds without tools: pull the tab, rotate the internal fiber holders 180°, and snap back into place. This eliminates the need to stock separate A-to-B and B-to-A polarity variants or perform re-termination during troubleshooting, cutting spares inventory and mean-time-to-repair in production environments. The reduced 2mm outer diameter creates routing flexibility in shallow cable trays and zero-U vertical managers where 3mm duplex cords bind or exceed the minimum bend radius, and allows denser bundling through grommets and pass-throughs without exceeding conduit fill ratios.

OM5 fiber extends the usable distance for 40GBASE-SR4 and 100GBASE-SR4 from OM4's 100-150 meters to a consistent 100 meters while adding native support for four-wavelength SWDM transmission. This future-proofs horizontal datacenter links and equipment-room backbone connections against protocol migrations—when upgrading from 10G to 40G or 100G, existing OM5 infrastructure supports the new data rate without re-cabling. The ultra-low insertion loss specification (typically <0.15dB, well below the 0.35dB maximum) preserves link budget headroom in multi-tier architectures where signals traverse multiple patch panels, cassettes, or cross-connects between source and destination. In a typical three-tier spine-leaf topology with four mated connector pairs per path, standard-loss cords would consume 1.0-1.4dB; Panduit's ultra-low loss design reduces total connector loss to 0.5-0.6dB, leaving additional margin for aging, contamination, and future adds without triggering bit-error-rate degradation.

The LSZH jacket is engineered for installations where building codes or corporate standards prohibit PVC due to toxic smoke and hydrochloric acid release during combustion. IEC 60332-1-2 certification confirms the cable self-extinguishes and limits flame spread, meeting the intent of NFPA 75 (electronic equipment rooms) and IEC 61034 low-smoke requirements without requiring plenum-rated construction. Lime green color coding per TIA-598-D prevents accidental cross-connection between OM5 and older OM3/OM4 links during MAC operations—visually distinct jackets reduce human error when technicians work in racks with mixed fiber types. At 4 meters (13.12 feet), this cord suits intra-rack switch-to-server connections, rack-to-rack adjacencies in the same row, and short patch-panel-to-switch jumps in telecommunications rooms. Standard polarity (key-up to key-up) aligns with TIA-568 Type A or Method A deployments; pair with Panduit's polarity-reversing uniboot mechanism for Type B or Method B configurations without stocking duplicate SKUs.
