Panduit FZ2ERLNLNSNM012 OM4 Multimode Fiber Patch Cord
The Panduit FZ2ERLNLNSNM012 is a 12-meter duplex LC/LC OM4 multimode fiber optic patch cord engineered for 10 Gigabit Ethernet and high-speed data center interconnects. Built on laser-optimized 50/125 µm OM4 fiber with aqua OFNR riser-rated jacketing, this pre-terminated assembly delivers the low modal dispersion required for 10GBASE-SR links up to 400 meters and 40/100GBASE-SR4 applications up to 150 meters. Panduit factory-terminates each connector under controlled conditions and certifies insertion loss to meet or exceed TIA-568 and ISO/IEC 11801 standards, eliminating the variability and labor cost of field terminations in equipment rooms and telecommunications closets.
Key Features
- OM4 Laser-Optimized Fiber: 50/125 µm core/cladding with 4700 MHz·km effective modal bandwidth at 850 nm supports 10GbE to 400 m, 40GbE to 150 m, and 100GbE to 150 m per IEEE 802.3 and TIA-568.3-D
- Duplex LC Connectors: Pre-polished LC duplex connectors with ceramic ferrules meet IEC 61754-20 physical contact specifications; typical insertion loss ≤0.35 dB, return loss ≥20 dB
- 12-Meter Reach: Spans rack-to-rack, row-to-row, or floor-to-floor connections in mid-sized data centers and telecom infrastructure without mid-span splicing
- 1.6 mm Riser Jacket: OFNR-rated PVC jacket (UL 1666 NFPA 262) provides flame resistance for vertical riser pathways; 1.6 mm zipcord construction balances flexibility with durability during pulls
- Aqua Color Code: Industry-standard aqua jacket identifies OM4 fiber at a glance, preventing cross-connection errors in mixed OM3/OM4 plants
- Backwards Compatible: Supports legacy 1000BASE-SX and OM3 10GBASE-SR equipment, protecting investment during phased network upgrades
- Factory Tested: Each jumper undergoes automated insertion loss and return loss testing; test reports available on request for documentation-heavy projects
- Low Bend Radius: 30 mm minimum bend radius (loaded) allows tight routing in high-density patch panels and cable managers without optical performance degradation
OM4 fiber's lower modal dispersion compared to OM3 is critical when running 10GBASE-SR optics near the 300-meter boundary or when planning future 40/100GbE migrations without re-cabling horizontal runs. The 50 µm core diameter maintains compatibility with 850 nm VCSEL transceivers—the cost-effective standard for short-reach datacenter optics—while the 4700 MHz·km bandwidth (vs. OM3's 2000 MHz·km) extends usable distance and reduces bit error rates on high-speed links. Panduit's manufacturing process ensures core-to-ferrule concentricity within 1.0 µm and end-face geometry per IEC 61300-3-35, directly impacting the 0.35 dB insertion loss ceiling. For SAN fabrics, server-to-switch uplinks, and storage array interconnects where every tenth of a dB counts toward link budget margin, factory precision beats field terminations. The duplex LC form factor is ubiquitous in Cisco, Arista, Juniper, and Dell switching/routing platforms; breakout to SC or MPO trunk cables is straightforward with Panduit's cassette and adapter ecosystem.
This 12-meter length addresses the middle ground between equipment-room patch cords (1–3 m) and inter-floor backbone cables (30+ m). In raised-floor data centers it spans from end-of-row aggregation switches to core routers two racks away; in telecom closets it connects floor distributors to riser backbone panels without custom-length delays. The 1.6 mm zipcord jacket strikes a balance: robust enough for multiple installs/removals during MAC (moves, adds, changes) cycles, yet flexible enough to route through congested vertical cable managers and horizontal troughs without kinking. OFNR riser rating satisfies NEC Article 770.113 for vertical pathways between floors in commercial buildings; for plenum spaces above drop ceilings you'll need Panduit's OFNP equivalent. Aqua jacketing is the TIA-598-C standard for OM4—critical in plants mixing OM3 (aqua or sometimes erika violet) and OM4, where a plugging error can silently limit a 10GbE link to 1GbE speeds or introduce intermittent errors under load.
Panduit backs this assembly with a comprehensive warranty when installed per TIA-568 guidelines and registered within 90 days. The factory test report confirms compliance with TIA-568.3-D Tier 1 component specs and IEC 61753-1 connector performance grades, satisfying the documentation requirements for LEED, BICSI RCDD projects, and federal installations requiring full traceability. For integrators building out 10GbE top-of-rack fabrics, refresh projects migrating from copper to fiber, or storage networks where latency and jitter matter, this pre-terminated OM4 jumper eliminates field termination labor, reduces troubleshooting time with guaranteed performance, and establishes the physical layer foundation for 40/100GbE upgrades as transceiver economics improve.
