Panduit FZ2RLU1U1NNM8.5 OM4 LC Uniboot 8.5m Fiber Cord

Panduit FZ2RLU1U1NNM8.5 OM4 LC Uniboot Duplex Fiber Patch Cord

The Panduit FZ2RLU1U1NNM8.5 is an 8.5-meter (27.9-foot) OM4 multimode fiber patch cord built for high-speed data center, campus backbone, and AV-over-IP applications where insertion loss and cable density directly impact system performance. This duplex patch cord uses LC Uniboot connectors in a single 2.0mm LSZH jacket, delivering ultra-low insertion loss (typically ≤0.15 dB) for 10GBASE-SR links to 400 meters, 40G/100G Ethernet to 100 meters, and emerging 200G/400G applications. The uniboot form factor cuts cable bulk in half compared to traditional duplex LC cords, simplifying routing in congested pathways and reducing strain on breakout panels in 1U fiber enclosures. LSZH jacket construction meets plenum-equivalent fire safety requirements for indoor vertical risers and horizontal distribution without the toxic-fume risk of PVC jackets during fire events.

Key Features

• OM4 multimode fiber rated for 10GBASE-SR to 400m, 40G/100G Ethernet to 100m per IEEE 802.3
• Ultra-low insertion loss specification (typically ≤0.15 dB) preserves link budget in multi-tier structured cabling
• LC Uniboot connectors with integrated pull-boot strain relief and field-reversible polarity
• 2.0mm LSZH (Low Smoke Zero Halogen) outer jacket for plenum and riser installations
• 8.5-meter (27.9-foot) length supports typical equipment-row spacing in data centers and A/V racks
• Duplex configuration in single-cable assembly reduces pathway congestion by 50% vs. dual-cable duplex LC
• Factory-terminated and tested to TIA-568.3-D OM4 performance standards

OM4 laser-optimized multimode fiber is the industry standard for short-reach 10G, 40G, and 100G Ethernet links in enterprise data centers and high-bandwidth commercial buildings. Panduit's ultra-low-loss variant maintains insertion loss below 0.15 dB per connector pair—critical when cascading multiple patch panels or consolidation points in structured cabling systems. A typical three-tier data center architecture (server → ToR switch → spine switch → core) consumes 0.6–1.0 dB in connector loss alone; choosing ultra-low-loss cords preserves 0.3–0.5 dB of margin compared to standard 0.3 dB cords, extending usable distance or accommodating future splices without link budget failure. The 50-micron core and 850nm laser-optimized refractive index profile support 10GBASE-SR to 400 meters and OM4-compliant 100GBASE-SR4 (4×25G lanes) to 100 meters per IEEE 802.3bm. LSZH jacket material complies with IEC 60332-3-24 flame propagation limits and IEC 61034-2 smoke density limits, meeting building codes in Europe, Middle East, and Asia-Pacific regions where PVC is restricted in occupied spaces; U.S. installations benefit from reduced toxic-fume generation during fire events even where not code-mandated.

The LC Uniboot connector design consolidates both fibers of a duplex link into a single push-pull boot, cutting cable bundle diameter and weight in half compared to traditional duplex LC patch cords with separate 1.6mm or 2.0mm jackets per fiber. This density improvement matters in 1U breakout panels serving 96-strand backbone cables, where traditional duplex LC cords create rigid bundles that exceed the bend-radius limits of OM4 fiber (30mm minimum) and obstruct airflow in the cable management trays. The integrated pull-boot provides strain relief during insertion and extraction, reducing the risk of connector endface damage or fiber stress fractures at the ferrule crimp point—common failure modes in cords without boots that are pulled at shallow angles. Field-reversible polarity is achieved by rotating the duplex connector body within the boot, swapping transmit and receive fibers without re-termination; this capability simplifies A-side to B-side conversions in trunk-to-patch polarity schemes (Method A/B per TIA-568.0-D Annex A). The 8.5-meter length is optimized for row-to-row switch uplinks in data centers with 7–8 meter equipment spacing, A/V rack uplinks in conference centers and control rooms, and security NVR uplinks where recorders are located in adjacent equipment closets from camera PoE switches.

Panduit factory-terminated fiber patch cords are built to TIA-568.3-D insertion loss limits (≤0.3 dB per mated connector pair for OM4) and return loss minimums (≥-20 dB), with batch testing and serialized quality records. The aqua-colored jacket identifies OM4 fiber per TIA-598-D color-coding standards, preventing mismatched fiber types during installation. This cord meets TIA-568.3-D and ISO/IEC 11801-1 OM4 specifications for 10G/40G/100G multimode applications, supporting equipment lifecycles of 10–15 years in climate-controlled environments. Investing in ultra-low-loss variants preserves link budget margin for future splices, dirty connector events, or migration to higher-speed transceivers (200G/400G) that operate closer to receiver sensitivity thresholds.
