Panduit FZ2RLU1U1NNM6.5 OM4 Uniboot Fiber Patch Cable

Panduit FZ2RLU1U1NNM6.5 OM4 LC Uniboot Fiber Patch Cable

The Panduit FZ2RLU1U1NNM6.5 is a 6.5-meter duplex OM4 multimode fiber jumper engineered for high-density datacenter and enterprise backbone deployments requiring 10/40/100 Gigabit Ethernet transmission. Built with LC Uniboot connectors and a 2.0mm LSZH jacket, this cable delivers ultra-low insertion loss performance while occupying half the footprint of traditional duplex LC patch cords. Designed for IT managers and fiber installers working in space-constrained racks, high-rise buildings subject to fire codes, or multi-tenant environments where plenum-rated cabling is mandatory.

Key Features

• OM4 50/125µm multimode fiber supports 10GBASE-SR up to 400m, 40GBASE-SR4 up to 150m, and 100GBASE-SR10 up to 100m per IEEE 802.3 standards
• LC Uniboot connector design consolidates duplex A-B polarity into a single-body connector, reducing panel port consumption by 50% compared to standard duplex LC
• Ultra-low insertion loss construction minimizes signal attenuation across backbone links, extending reach in campus and datacenter distribution layers
• 2.0mm cable diameter (versus 3.0mm industry-standard duplex) enables tighter bend radius and higher cable density in vertical cable managers and horizontal troughs
• LSZH (Low Smoke Zero Halogen) outer jacket meets IEC 60332-1 and IEC 61034 fire safety standards for plenum and riser installations without PVC combustion byproducts
• Pull-boot connector housing provides positive grip surface for technician removal in congested patch panels without stressing the ferrule or cable strain relief
• Aqua jacket color per TIA-598-C OM4 industry standard allows instant visual identification during adds/moves/changes
• 6.5-meter length suits cross-rack connections in mid-sized datacenters, IDF-to-switch uplinks, or storage array-to-SAN fabric links
• Factory-terminated and tested to meet Panduit's insertion loss and return loss specifications, eliminating field termination labor and measurement uncertainty

The OM4 multimode fiber core in the FZ2RLU1U1NNM6.5 uses laser-optimized 50-micron glass with a minimum effective modal bandwidth (EMBc) of 4700 MHz·km at 850nm, a mandatory threshold for 100-meter 100GBASE-SR4 transmission per IEEE 802.3bm. This bandwidth specification distinguishes OM4 from OM3 (2000 MHz·km EMBc), allowing datacenter architects to deploy 40G and 100G parallel optics across longer spans without upgrading to single-mode infrastructure. The LC Uniboot connector replaces the traditional dual-boot duplex LC configuration with a single rectangular body housing both transmit and receive ferrules in a push-pull latch mechanism. This consolidation reduces the physical width requirement at the patch panel faceplate from approximately 13.6mm (two standard LC connectors side-by-side) to 6.9mm (single Uniboot body), effectively doubling port density in 1U 24-port or 48-port LC cassette modules. The polarity is factory-set as Method-B (straight-through A-to-A, B-to-B) per TIA-568-C.3 Annex A, which directly interfaces with MPO-to-LC breakout cassettes in structured cabling systems without crossover adapters. Insertion loss performance is specified as "ultra-low" in Panduit's product tier, typically 0.15 dB or lower per mated connector pair, compared to 0.25 dB for standard-grade LC connectors; this 0.10 dB margin per connection point accumulates across multi-hop storage fabrics or spine-leaf topologies, preserving link budget for extended-reach optics or additional passive splits.

The 2.0mm outer diameter cable construction uses a tight-buffered dual-fiber design with aramid yarn strength members and an LSZH thermoplastic outer sheath rated for vertical riser (OFNR) and plenum (OFNP) installations per NEC Article 770. LSZH compounds are required in European Union installations under the Construction Products Regulation (CPR) Euroclass fire classifications, specifically Cca, Dca, or Eca ratings depending on building occupancy type. In North American high-rise commercial or healthcare facilities, LSZH cabling is often specified by architects and MEP engineers to limit toxic hydrogen chloride and particulate smoke generation during a fire event, particularly in return-air pathways or spaces above suspended ceilings where PVC jacketed cables would otherwise be prohibited without conduit. The 2.0mm diameter allows tighter minimum bend radius (typically 10× cable diameter = 20mm dynamic, 15× = 30mm static) compared to 3.0mm duplex jumpers, enabling cleaner routing through crowded vertical wire management channels in 42U or 48U racks where horizontal space between the rear equipment rails and the cabinet door is often limited to 100-150mm. The pull-boot design extends a ribbed polymer tab 15-20mm beyond the connector latch, giving installers a positive tactile grip point when extracting cables from densely populated patch panels or SFP+ cages where finger access to the latch itself is obstructed by adjacent connectors. This reduces accidental ferrule endface contamination from finger oils and minimizes strain on the cable-to-connector boot interface that can lead to kinking or jacket damage at the stress relief point.

Panduit's factory-terminated fiber jumpers undergo automated endface polishing to achieve physical contact (PC) geometry with an apex offset under 50µm and a radius of curvature between 10-25mm per IEC 61755-3-1, then pass insertion loss and return loss testing on calibrated Optical Time Domain Reflectometers before shipment. This QC process eliminates the field labor and equipment cost associated with fusion splicing or mechanical splice terminations, and removes measurement uncertainty from hand-polished connectors that often fail to meet the 0.35 dB IL maximum specified in TIA-568.3-D for multimode connections. The 6.5-meter length is a non-standard size optimized for cross-aisle rack-to-rack links in datacenters with hot-aisle/cold-aisle layouts where the aisle width plus half the depth of two racks totals approximately 5-7 meters, reducing the need for 10-meter jumpers that introduce excess coiled slack and unnecessary attenuation.
