Panduit FW2ERQ1Q1NNF037 3.7m LC-LC OM4 Duplex Patch Cable

Panduit FW2ERQ1Q1NNF037 LC-LC Duplex Multimode Fiber Patch Cable

The Panduit FW2ERQ1Q1NNF037 delivers a 3.7-meter (12.1 ft) duplex LC-to-LC fiber optic interconnect engineered for OM4 50/125 µm multimode applications in enterprise datacenters, structured cabling systems, and high-speed networking environments. Aqua jacket identifies the OM4 rating at a glance during moves-adds-changes. Riser-rated (OFNR) jacket meets NEC 770.113(B) for vertical riser pathway installation between floors without requiring conduit in plenum-free zones. Factory-terminated LC connectors ship pre-polished to better than 0.2 dB insertion loss, eliminating field termination labor and ferrule endface contamination risk on day-one deployments.

Key Features

• LC duplex to LC duplex connectors — industry-standard small form factor for SFP/SFP+ transceiver modules in switches, media converters, and fiber NICs
• OM4 50/125 µm multimode fiber — supports 10GBASE-SR up to 400 meters, 40GBASE-SR4 to 150 meters, 100GBASE-SR4 to 150 meters per IEEE 802.3 specifications
• 3.7-meter (12.1 ft) fixed length — precision-cut for rack-to-adjacent-rack horizontal runs, equipment-to-patch-panel interconnects, or cross-connect field jumpers in telecommunications rooms
• Riser-rated OFNR jacket — NEC Article 770 compliant for vertical installation in non-plenum shafts and risers without additional raceway protection
• Aqua PVC jacket — immediate OM4 visual identification per TIA-598-D fiber color coding standard, reducing mis-patching during MAC work
• Factory-terminated and tested — every assembly ships with insertion loss ≤0.2 dB and return loss ≥20 dB (PC polish) verified at 850 nm wavelength
• Low-profile duplex LC boot — strain relief protects ferrule alignment during repeated connect/disconnect cycles, withstands 500+ mating operations per IEC 61754-20
• Zirconia ceramic ferrule — dimensional stability across -20°C to +70°C operating range prevents core misalignment that degrades optical performance in thermally cycling equipment rooms

Panduit constructs the FW2ERQ1Q1NNF037 using laser-optimized 50/125 µm OM4 multimode fiber with 4700 MHz·km effective modal bandwidth at 850 nm, purpose-built for VCSEL-based 10G/40G/100G Ethernet transceivers. The 3.7-meter length addresses the common datacenter scenario where structured cabling horizontal outlets land 10–12 feet from the switch or server front panel — too short for a 5-meter standard jumper (creates slack management problems) and too long for a 2-meter cable (won't reach). Duplex LC connectors mate with SFP+ modules in Cisco Catalyst / Nexus switches, HPE Aruba / ProCurve platforms, Juniper EX-series, Dell PowerConnect, and virtually all enterprise networking gear manufactured since 2010. Each connector uses physical contact (PC) polish on the zirconia ferrule endface, achieving ≤0.2 dB insertion loss through sub-micron core alignment and air-gap elimination at the mated interface.

The riser-rated (OFNR) PVC jacket contains flame-spread within the limited combustible load requirements of NEC 770.113(B), making this cable code-compliant for vertical runs in telecommunications closets, riser shafts, and equipment room floor-to-floor pathways where plenum-rated cable is not mandated. Aqua jacket color follows TIA-598-D Annex A fiber color coding — OM4 = aqua, OM3 = aqua, OM2 = orange, OS2 = yellow — enabling installers to verify fiber type during patching without consulting documentation or conducting OTDR tests. In mixed-mode environments (OM3 backbone with OM4 horizontal), the color distinction prevents accidentally patching OM2 legacy fiber into a 40GBASE-SR4 link that requires OM3 minimum. The duplex LC connector configuration maintains A-to-A / B-to-B polarity alignment when following TIA-568.3-D Method B polarity scheme in a structured cabling system; for Method A deployments, use a crossover patch cable at one end or deploy MPO trunk assemblies with appropriate fanout modules.

Deploy the FW2ERQ1Q1NNF037 in horizontally structured OM4 cabling systems per TIA-568.3-D, where permanent link fiber terminates at wall outlets or consolidation points and equipment cords provide the final device interconnect. The 3.7-meter length suits rack-to-rack connections in hot-aisle/cold-aisle layouts with 42U cabinets on 4-foot centers, leaving adequate service loop for future equipment swaps without cable replacement. Factory termination eliminates the field labor cost and performance variability of on-site LC connector installation — Panduit's automated polishing process produces consistent ferrule geometry and endface finish that hand-polished connectors rarely achieve. For installations requiring TIA-526-14-B Tier 1 (basic) or Tier 2 (extended) certification, the ≤0.2 dB insertion loss spec and ≥20 dB return loss spec provide margin against the 0.75 dB maximum channel loss budget typical of 10GBASE-SR links under 100 meters. Zirconia ceramic ferrules resist wear during the 500+ insertion cycles common in dynamic datacenter environments where server moves, blade chassis reconfigurations, and switch upgrades drive frequent repatching — steel or plastic ferrules deform after 50–100 cycles, increasing insertion loss and eventual link failure.
