Panduit FS2RPU1U1NNM011 Signature Core OM4+ 11-Meter LC Uniboot Fiber Patch Cord

When you're engineering high-density datacenter fabrics or upgrading to 40/100 Gigabit Ethernet, insertion loss budgets and pathway congestion become critical constraints that determine whether your architecture scales or stalls. The Panduit FS2RPU1U1NNM011 Signature Core OM4+ fiber patch cord addresses both challenges head-on with ultra-low insertion loss optics and space-efficient uniboot design. This 11-meter plenum-rated jumper terminates LC duplex uniboot connectors at both ends, delivering 50/125μm multimode performance that extends 100GBASE-SR4 reach to 150 meters—50% farther than standard OM4 and 87% farther than OM3. For integrators installing spine-leaf topologies, SAN interconnects, or 40G/100G server uplinks where every dB matters and every square inch of cable tray counts, this pre-terminated assembly eliminates field termination risk while cutting pathway fill by half versus traditional dual-boot designs.

Key Features

• OM4+ 50/125μm laser-optimized multimode fiber extends 100GBASE-SR4 to 150m, 40GBASE-SR4 to 150m (vs. 100m for OM4, 70m for OM3)
• LC duplex uniboot connectors on both ends reduce pathway fill 50% compared to dual-boot assemblies and enable field polarity reversal without re-termination
• Pull-boot strain relief design isolates mechanical stress from connector ferrule during moves, adds, and changes in cramped rack environments
• Ultra-low insertion loss design (typically <0.15 dB per connector) preserves link budget in multi-tier datacenter architectures with multiple interconnect points
• Plenum (OFNP) rated jacket meets NEC 770.179(C) for installation in air-handling spaces, drop ceilings, and raised-floor plenums
• Aqua jacket color provides instant OM4 fiber identification per TIA-598-D color code standards for field technicians and future maintenance
• 11-meter (36-foot) length optimized for inter-rack and cross-aisle datacenter connections without excessive coiling or pathway clutter
• Factory pre-terminated with NIST-traceable test results eliminates field polish defects and accelerates deployment timelines

Panduit's Signature Core OM4+ cable uses laser-optimized 50-micron core geometry that delivers effective modal bandwidth exceeding 4700 MHz·km at 850nm—the performance tier that unlocks extended-reach 40/100G applications without the cost penalty of OM5 wideband or singlemode infrastructure. Standard OM4 fiber supports 100GBASE-SR4 to 100 meters and 40GBASE-SR4 to 100 meters; OM4+ pushes those distances to 150 meters, giving you the margin to span longer datacenter rows, add an extra aggregation tier in spine-leaf topologies, or interconnect buildings in campus environments without resorting to costlier singlemode transceivers. That extra 50 meters of reach is the difference between a two-tier and three-tier fabric in many colocation or enterprise datacenter footprints. The uniboot connector assembly packages both transmit and receive fibers in a single compact housing roughly half the width of traditional duplex LC boots. In high-density switch ports where you're populating 36 or 48 QSFP28 breakout ports in a single rack unit, that space savings translates directly to improved airflow around faceplate openings, reduced bend stress at the minimum bend radius, and simpler cable management when you're dressing bundles into vertical or horizontal pathways. The pull-boot retention system uses a flexible strain-relief body that absorbs tension during installation and MAC work—critical when you're working in cramped rear-of-rack spaces where accidental tugs can unseat connectors, damage ferrule endfaces, or pull equipment forward in the rack. Panduit specifies ultra-low insertion loss performance (typically <0.15 dB per connector, guaranteed <0.35 dB per mated pair) which preserves your optical power budget when you're chaining multiple patch panels, MTP cassettes, or cross-connects in large enterprise or colocation environments. In a three-tier leaf-spine-core topology with four interconnect points, the difference between 0.15 dB and 0.5 dB per connection is 1.4 dB of total link loss—enough to push marginal links below receiver sensitivity thresholds and trigger intermittent errors under temperature or aging stress.

The 11-meter (36-foot) length is engineered for inter-rack and cross-aisle connections in structured datacenter environments—long enough to span typical row-to-row distances (8-10 meters) or connect top-of-rack switches to middle-of-row aggregation points, yet short enough to avoid excessive service loops and pathway congestion that complicate future additions. You'll deploy this jumper in spine-leaf fabrics interconnecting Cisco Nexus 9000, Arista 7000 series, or Juniper QFX switches; in SAN fabrics linking all-flash arrays to 32G Fibre Channel directors; in 40GBASE-SR4 or 100GBASE-SR4 server uplinks using QSFP+ or QSFP28 parallel optics with MPO-to-LC breakout modules; and in pre-terminated MTP-to-LC cassette cross-connects where maintaining TIA Method B polarity and minimizing loss across the permanent link is non-negotiable. Plenum (OFNP) jacket rating is mandatory for any cable routed through return-air plenums, drop ceilings, raised floors, or HVAC ducts that qualify as air-handling spaces under NEC Article 770. Non-plenum cable in these areas is a code violation that fails inspection, triggers insurance exclusions, and creates liability exposure in the event of fire. The OFNP rating certifies that jacket materials limit flame spread to 5 feet or less and produce minimal smoke—requirements verified through UL 910 Steiner Tunnel testing. The aqua jacket matches TIA-598-D color convention for OM4 fiber (and OM4+ by extension), so your team can identify 50μm multimode links at a glance during troubleshooting or future upgrades without referencing as-built documentation or relying on inconsistent labeling practices from prior contractors.

Panduit's Signature Core line represents the company's premium tier for mission-critical structured cabling, with tighter manufacturing tolerances and third-party validation against TIA-568.3-D insertion loss, return loss, and geometry specifications. Every cord ships with individual test results traceable to NIST standards, documenting insertion loss, return loss, and length measurements for both fibers—giving you the paper trail that enterprise change-control processes, contractor compliance audits, and warranty claims require. The factory pre-termination eliminates the variability introduced by field-polish methods: no risk of contaminated endfaces from airborne particulates, over-polished or under-polished cores from inconsistent hand pressure, improper epoxy curing from temperature or humidity swings, or ferrule geometry defects from worn polishing films. Field termination carries a 5-15% defect rate even with trained technicians; factory termination in controlled cleanroom environments brings that below 0.1%. For integrators managing multi-year datacenter builds, large-scale virtualization migrations, or storage consolidation projects where downtime windows are measured in minutes and optical link failures trigger SLA penalties or revenue loss, this cord's combination of extended OM4+ reach, uniboot density advantages, plenum code compliance, and Panduit's 25-year warranty coverage makes it the straightforward choice for 40/100G multimode deployments that need to work correctly the first time and remain in service through multiple equipment refresh cycles.
