Panduit FS2RLU1U1NNM004 4m OM4+ LC Uniboot Patch Cord

Panduit FS2RLU1U1NNM004 OM4+ Signature Core Fiber Patch Cord

The Panduit FS2RLU1U1NNM004 is a 4-meter duplex OM4+ Signature Core multimode fiber patch cord engineered for high-performance datacenter and enterprise network infrastructure. This professional-grade jumper features LC Uniboot connectors on both ends with integrated pull-boot design for tool-free polarity reversal, ultra-low insertion loss for maximum signal integrity, and LSZH (Low Smoke Zero Halogen) jacketing for life-safety compliance in occupied spaces. OM4+ Signature Core fiber delivers higher bandwidth density and extended reach compared to standard OM4, supporting 100GBASE-SR4 applications up to 150 meters and future-proofing installations for 400G migrations. The space-saving Uniboot form factor reduces cable bulk by 50% versus traditional duplex LC cordage, critical for maintaining airflow and accessibility in dense patch panel environments. Aqua jacket color provides instant visual identification of 50µm multimode infrastructure per TIA-598 color coding standards.

OM4+ Signature Core fiber represents Panduit's premium multimode offering, engineered to outperform standard OM4 specifications through tighter manufacturing tolerances on core geometry, numerical aperture, and bandwidth. The "Plus" designation indicates guaranteed minimum effective modal bandwidth (EMBc) of 4700 MHz·km at 850nm—17% higher than the 4000 MHz·km OM4 minimum—translating directly to longer supported distances for 40GBASE-SR4 and 100GBASE-SR4 applications. In practical terms, this patch cord supports 100GBASE-SR4 links up to 150 meters versus 100 meters for standard OM4, a critical advantage when spanning multiple rows in hyperscale datacenters or connecting across floors in enterprise campus buildings. The ultra-low insertion loss specification (typically <0.15 dB per connector versus the 0.75 dB TIA maximum) preserves link budget for installations using multiple interconnect points, allowing you to maintain performance headroom even in complex architectures with multiple patch panels, cross-connects, or media converters in the signal path. This becomes essential when operating near the maximum distance limits of 40G/100G optics or when planning for future transceiver generations with tighter loss budgets.

The LC Uniboot connector design consolidates the traditional dual-boot duplex LC form factor into a single compact housing, reducing the physical footprint at the patch panel by approximately 50% compared to standard LC duplex cordage with separate 1.6mm zipcord legs. This space efficiency directly impacts usable port density in high-count MTP-to-LC breakout cassettes and allows installers to maintain the 1-inch minimum bend radius even in fully populated 1RU panels with 144+ LC ports. The integrated pull-boot mechanism is the key operational advantage: by simply pulling the boot away from the connector body, the internal fiber stub rotates 180°, reversing transmit and receive pairs without removing the cable from the panel or requiring a physical swap at the far end. This eliminates the most common source of polarity errors during structured cabling installation—incorrectly specifying A-B versus A-A patch cord orientation—and allows technicians to correct polarity mismatches in seconds during troubleshooting without disrupting adjacent links. The boot itself is molded from flexible, snag-resistant polymer that protects the connector during installation and provides a secure grip point for extraction from recessed panel ports, while the strain relief design maintains the 2.0mm cable bend radius to prevent fiber overstress in tight routing paths behind rack-mounted equipment.

This 4-meter length targets three primary deployment scenarios in commercial network infrastructure. First, intra-rack connections between top-of-rack switches and servers or storage arrays mounted 10-20RU away, where the 13-foot length provides enough slack for proper cable dressing along vertical wire managers without excess coil buildup that impedes airflow. Second, cross-connect jumpers in main distribution areas (MDA) or horizontal distribution areas (HDA), patching between backbone fiber cassettes and active switching equipment located in adjacent racks or across hot/cold aisle configurations typical of contained datacenter designs. Third, equipment-to-wall-port connections in telecommunication rooms serving office floors, where the aqua OM4+ jumper links the user's switch or router to the building's permanent 50µm multimode plant for inter-floor connectivity to the datacenter. The LSZH jacket is the required specification for these applications in 90% of commercial installations: building codes in the U.S. (NEC Article 770), Europe (CPR Euroclass), and most international markets mandate low-smoke, halogen-free cables in return-air spaces, vertical risers, and any pathway not enclosed in metal conduit, due to the toxic hydrogen chloride gas released by PVC jacketing during fire events. Panduit's LSZH compound meets IEC 60754-1 (halogen content <0.5%) and IEC 61034 (light transmittance >60% during smoke test), ensuring code compliance without requiring the added cost and installation complexity of conduit or plenum-rated cable trays.

Factory termination and testing to TIA-568-C.3 and ISO/IEC 11801 standards ensures every patch cord in this product line ships with guaranteed insertion loss, return loss, and geometry compliance verified via automated interferometric and optical time-domain test equipment. Each connector endface is inspected at 400x magnification per IEC 61300-3-35 to verify <1µm scratch width and zero zone-A defects that would cause back-reflection or signal attenuation, then polished to sub-50nm surface finish for optimal physical contact with mating transceivers. This level of manufacturing rigor is what separates Panduit Signature Core cordage from commodity patch cords sourced through distribution: you're not gambling on field termination quality or relying on spot-check sampling—every meter of fiber and every connector in this assembly has been characterized and documented before it ships. For integrators managing SLA-backed datacenter or enterprise network deployments, that traceability translates directly to faster troubleshooting (you can eliminate the patch cord as a variable immediately) and defensible acceptance testing when commissioning links for customer handoff.
