Panduit FS2RPU1U1NNM1.5 Signature Core OM4+ LC Duplex Fiber Optic Patch Cord
The Panduit FS2RPU1U1NNM1.5 is a 1.5-meter OM4+ multimode fiber patch cord engineered for high-density datacenter and enterprise network deployments requiring ultra-low insertion loss and 40/100 Gigabit Ethernet performance. Featuring duplex LC uniboot connectors on both ends, this plenum-rated (OFNP) jumper delivers space-efficient connectivity for spine-leaf architectures, SAN storage networks, and pre-terminated cassette systems while meeting TIA-568-C.3 and ISO/IEC 11801 structured cabling standards. Panduit's Signature Core manufacturing process ensures consistent geometry and loss performance across every connector interface.
Key Features
- OM4+ Ultra-Low Loss Performance: 50μm core diameter optimized for 850nm VCSEL transmission, supporting 40GBASE-SR4 to 150m and 100GBASE-SR4 to 100m with tighter insertion loss budgets than standard OM4 fiber
- Duplex LC Uniboot Connectors: Single-body uniboot design with pull-tab boot reduces patch panel footprint by 50% compared to dual-boot LC assemblies, simplifying polarity reversal and cable management in congested pathways
- 1.5-Meter Length: Optimized for intra-rack server-to-switch connections and short cross-connects in equipment distribution areas where cable slack management and airflow are critical
- Plenum-Rated Jacket (OFNP): Low-smoke, flame-retardant construction meets NEC Article 770 plenum space requirements for installation in air-handling ceilings and raised floors without conduit
- Aqua Jacket Color: Industry-standard OM4 color coding per TIA-598-D enables instant visual identification of multimode 50μm laser-optimized fiber in mixed-mode installations
- TIA-568-C.3 Compliant: Factory-terminated and tested to meet ANSI/TIA insertion loss, return loss, and geometric requirements for Category OM4 fiber optic cabling
OM4+ Insertion Loss and Link Budget Advantages: Standard OM4 multimode fiber (ISO/IEC 11801 Category OM4) specifies 850nm attenuation of 3.0 dB/km maximum. Panduit's OM4+ Signature Core construction tightens manufacturing tolerances to deliver typical attenuation below 2.3 dB/km—a critical margin when your 40G/100G transceiver budget includes multiple interconnects, cassettes, and trunk cables. In a typical spine-leaf deployment with four patch cord interfaces per 100m link (server NIC → ToR → spine → ToR → storage array), reducing per-connector insertion loss from 0.35 dB to 0.20 dB recovers 0.60 dB of margin—enough to extend reach by 15–20 meters or accommodate an additional mid-span cassette for flexible reconfiguration. The LC duplex uniboot form factor amplifies this advantage: by consolidating two simplex connectors into a single keyed housing, you eliminate one potential point of contamination and misalignment while cutting patch panel real estate in half. In 1RU 144-fiber panels, uniboot assemblies deliver the same port density as MPO cassettes but with the field-swappable simplicity of duplex LC—no breakout modules, no polarity headaches, no tech truck rolls to swap a single failed fiber.
Datacenter and Enterprise Deployment Contexts: The 1.5-meter length of the FS2RPU1U1NNM1.5 is purpose-built for the three most common short-reach scenarios in modern datacenter and telecom room infrastructure. First, intra-rack server uplinks: connecting blade chassis, pizza-box servers, or hyper-converged nodes at the bottom of a 42RU rack to a top-of-rack (ToR) switch requires 1.2–1.8m of dressed length after accounting for vertical cable management arms and service loops—this assembly lands in the sweet spot without excess slack that blocks airflow or tangles on cable fingers. Second, spine-leaf horizontal cross-connects: in leaf-spine fabrics where ToR switches mount in the same row as spine switches (common in single-row pod designs or small enterprises), 1.5m jumpers bridge adjacent racks or span two rack positions with minimal sag. Third, SAN and storage array interconnects: Fibre Channel 32GFC and 64GFC storage networks demand OM4 or better for reliable 850nm multimode links; the FS2RPU1U1NNM1.5 provides a cost-effective alternative to single-mode fiber when your fabric is contained within a single room and you want to preserve the installed base of multimode trunk infrastructure. In all three contexts, plenum rating is non-negotiable if your AHJ enforces NEC Article 770 for cables installed above drop ceilings or in underfloor plenums—substituting a riser-rated (OFNR) or general-purpose (OFN) cable in a plenum space is a code violation that will fail inspection and void insurance coverage in the event of a fire.
Uniboot Pull-Tab Polarity Management: One of the persistent headaches in duplex multimode links is polarity reversal at the far end—Ethernet and Fibre Channel both require transmit-to-receive crossover, but pre-terminated assemblies from different manufacturers (or even different product lines from the same vendor) ship with inconsistent A-to-B vs. straight-through pinouts. The Panduit uniboot pull-tab boot solves this in the field: pull the tab, slide the duplex ferrule assembly out of the connector body, rotate it 180°, and reinsert—you've just swapped A and B fibers without re-terminating or carrying a crossover adapter. This is especially valuable in cassette-based systems (Panduit's own FHD TAP cassettes, or equivalent MTP-to-LC breakout modules) where the trunk polarity is fixed at installation and you need to adapt patch cords to match. In a 500-drop enterprise campus buildout, eliminating even one in ten tech-revisit calls for polarity correction pays for the delta between standard LC and uniboot LC assemblies.
The FS2RPU1U1NNM1.5 ships as a single patch cord (carton quantity: 10 per box for volume installs) and meets RoHS Directive 2002/95/EC for lead-free, environmentally responsible materials. Panduit's Signature Core manufacturing includes automated connector polish, interferometric inspection of ferrule endface geometry, and serialized insertion-loss testing at 850nm and 1300nm—every assembly ships with a test report traceable to NIST standards. This is the quality standard that separates a commodity Amazon jumper (which may work today but will cost you hours of troubleshooting when insertion loss drifts or a contaminated ferrule takes down a 100G link) from a patch cord engineered for 20-year structured cabling warranties and backed by a manufacturer who answers the phone when your integrator has a question. For datacenter operators managing thousands of fiber connections across multiple generations of Ethernet and Fibre Channel, the FS2RPU1U1NNM1.5 is a known-good component that fits into your existing OM4 infrastructure, interoperates with cassettes and trunk cables from any TIA-compliant vendor, and delivers predictable performance whether you're lighting up a single server or cutting over an entire pod.
