Panduit FS2RLU1U1NNM4.5 4.5-Meter OM4+ LC Uniboot Fiber Patch Cord

The Panduit FS2RLU1U1NNM4.5 delivers enterprise-grade 40/100G fiber connectivity in a space-efficient 2.0mm LSZH cable design. Built around Signature Core™ OM4+ multimode fiber with duplex LC Uniboot connectors, this 4.5-meter patch cord combines ultra-low insertion loss with the density advantages of a single-boot termination—critical when you're managing hundreds of links in 1U patch panels or congested switch fabrics. The LSZH jacket meets international fire-safety mandates for enclosed pathways, and the integrated pull-boot simplifies moves-adds-changes without risking connector damage.

Key Features

OM4+ Signature Core™ multimode fiber supporting 40/100GBASE-SR4 and future 400G applications over extended distances

Duplex LC Uniboot connectors with A-B polarity keying—single-boot form factor cuts patch-panel footprint in half versus dual-boot designs

Ultra-low insertion loss under 0.15 dB typical, minimizing link budget consumption in multi-tier spine-leaf architectures

2.0mm LSZH (Low Smoke Zero Halogen) cable jacket for plenum, riser, and international installations where PVC is prohibited

Integrated pull-boot strain relief for tool-free insertion and extraction in high-density arrays

4.5-meter (14.76 ft) length suits rack-to-rack connections within the same row or adjacent hot/cold aisles

OM4+ fiber extends the reach of 40GBASE-SR4 to 150 meters and 100GBASE-SR4 to 125 meters—enough headroom to span multiple equipment rows or connect edge-of-row switches to core aggregation layers without intermediate optics. Panduit's Signature Core manufacturing process tightens the mode-field diameter variance across the entire cable, reducing differential mode delay and supporting the IEEE 802.3bm extended-reach tables. When you're building out a two-tier leaf-spine fabric or refreshing a legacy 10G backbone, that extra margin translates directly into transceiver flexibility and future-proofing against 200G/400G migrations.

The LC Uniboot termination consolidates both transmit and receive fibers into a single compact connector body with an A-B polarity slide key. This halves the width occupied in MPO-to-LC breakout panels or SFP+ / QSFP28 faceplates, letting you populate all 48 ports on a 1U panel without overlapping boots or forcing alternating-row layouts. The pull-boot is molded as part of the strain relief, so field techs can grip the cord firmly during insertion and yank it free during cutovers—eliminating the ferrule-contact wear and broken latches that come from tugging the connector body itself. In lights-out data centers or cramped telco closets, that tactile difference matters.

LSZH cable construction meets IEC 60332-1, IEC 60332-3C, and IEC 61034 flammability and smoke-density standards, making this cord legal for installation in European, Asian, and MEA facilities where PVC jackets are restricted under building codes. The aramid-yarn strength member and low-friction outer sheath also improve pull tension during retrofit projects—you can route these cords through existing ladder rack or overhead J-hooks without exceeding the 100 N maximum pull force. For U.S.-based integrators working on multinational deployments or federal sites adopting low-smoke mandates, stocking LSZH inventory eliminates last-minute material swaps and change-order delays.
