Panduit FS2RPU1U1NNM050 Opti-Core OM4+ 50m LC Duplex Uniboot Fiber Assembly

The Panduit FS2RPU1U1NNM050 delivers factory-terminated 50-meter OM4+ multimode fiber infrastructure for high-density data center and telecommunications environments. This 2-fiber LC duplex uniboot assembly combines 50/125µm OM4+ glass with plenum-rated (OFNP) jacketing, supporting 40/100 Gigabit Ethernet over extended distances while meeting strict fire-safety requirements for air-handling spaces. The uniboot form factor reduces pathway congestion by 50% compared to dual-cable designs, and polarity is field-reversible without tools—critical when managing hundreds of interconnects across racks or between floors in enterprise telecom rooms.

Key Features

• OM4+ 50/125µm multimode fiber: Supports 40GBASE-SR4 to 150m, 100GBASE-SR4 to 100m, and 10GBASE-SR to 550m per TIA-568.3-D link budgets
• LC duplex uniboot connector: Single-boot design with tool-free polarity reversal; reduces cable-management volume and simplifies MACs (moves/adds/changes) in live production environments
• 50-meter pre-terminated length: Factory-polished end-faces eliminate field-termination labor and insertion-loss variability; ideal for inter-floor backbone runs or cross-building links in campus networks
• Plenum (OFNP) rated: UL 910 and NFPA 262 compliant for installation in air-handling plenums, vertical risers, and above suspended ceilings without additional conduit
• Opti-Core build quality: Low-loss PC (physical contact) polish, <0.15 dB typical insertion loss, <-50 dB return loss; each assembly is 100% factory-tested and serialized for end-to-end traceability
• Aqua jacket color-coding: Industry-standard OM4 identification per TIA-598-D; prevents cross-connection errors during installation and troubleshooting

OM4+ fiber delivers 4,700 MHz·km effective modal bandwidth at 850nm—substantially higher than legacy OM3 (2,000 MHz·km) and sufficient for 100GBASE-SR4 parallel optics without additional margin engineering. The 50/125µm core/cladding geometry pairs with VCSEL transceivers across Cisco, Arista, Juniper, and Dell EMC switching platforms, and the laser-optimized refractive index profile minimizes differential mode delay (DMD) that otherwise limits channel reach. Panduit specs each FS-series assembly to <0.15 dB insertion loss per mated pair—well below the 0.75 dB TIA-568.3-D channel budget allocation for two connectors—leaving headroom for patch-panel interconnects, in-line attenuators, or future splices without risking link margin violations. The PC polish geometry ensures sub-micron end-face contact, and the zirconia ceramic ferrules maintain <0.01 dB repeatability across 500+ mating cycles, critical in hyperscale data centers where technicians swap optics or re-patch daily.

The uniboot design consolidates both transmit and receive fibers into a single round jacket with one pull-tab, cutting pathway fill by half compared to duplex zipcord cables. For a 42U rack with 48 ports of 40G connectivity, this translates to 50% less cable volume in vertical managers and horizontal troughs—the difference between orderly airflow and a tangled nest that blocks cooling and complicates audits. Polarity reversal is tool-free: slide the retention clip, rotate the connector body 180°, and re-seat. This eliminates the need to stock Type A, Type B, and Type C polarity variants; a single SKU handles Method A (straight-through) and Method B (crossover) deployments, simplifying inventory and reducing order lead-times when expanding blade-server enclosures or spine-leaf fabrics. The round 2mm jacket profile also improves bend-radius performance—25mm minimum dynamic radius versus 38mm for flat duplex cables—allowing tighter routing around hinged patch panels and high-density MPO cassettes in 1U fiber enclosures.

This assembly ships with OFNP plenum jacketing that self-extinguishes in under 5 minutes per UL 910 Steiner Tunnel testing, meeting the NFPA 262 flame-propagation and smoke-density thresholds required by IBC Section 2702 and NEC Article 770 for cables installed in environmental air spaces. That compliance extends to vertical riser shafts and above-grid ceiling voids without metallic conduit, reducing material cost and installation labor on multi-floor telecom backbone projects. The cable is also RoHS-compliant and free of REACH-listed substances, satisfying EU Directive 2011/65/EU for multinational deployments. Panduit backs each Opti-Core assembly with a 20-year system warranty when installed per TIA-568.3-D guidelines, covering both the cable and connectors against performance degradation—a level of accountability that generic patch cords and field-terminated links cannot match. For integrators managing compliance-driven projects in finance, healthcare, or government sectors, this factory documentation and serialized test data provide the audit trail required by ISO 27001, HIPAA Technical Safeguards, and FedRAMP control baselines without additional field certification overhead.
