Panduit FW2ERQ1Q1NNM013 OM4 Duplex LC Fiber Patch Cord

Panduit FW2ERQ1Q1NNM013 is a 13-foot duplex multimode fiber optic patch cord with LC to LC connectors, built on OM4 laser-optimized 50/125µm fiber. The aqua jacket follows TIA-598-C color coding for instant OM4 identification in mixed-fiber environments. This assembly supports 40GBASE-SR4 and 100GBASE-SR4 Ethernet at distances up to 150 meters, making it a core component for datacenter spine-leaf architectures and high-speed SAN interconnects where OM3 cable plant has been exhausted.

Key Features

OM4 laser-optimized 50/125µm multimode fiber rated for 40/100G Ethernet

Duplex LC-to-LC connectors with ceramic ferrules and factory-polished endfaces

Aqua LSZH jacket for plenum compliance and TIA-598-C color-code adherence

0.35 dB maximum insertion loss per connector, tested at 850 nm wavelength

13-foot (4-meter) length for rack-to-rack or intra-rack datacenter patching

Method B polarity (key-up to key-up) for standard duplex transceiver compatibility

The FW2ERQ1Q1NNM013 uses Panduit's controlled-geometry ferrule process to hold connector insertion loss below 0.35 dB and return loss above 20 dB across the 850 nm and 1300 nm windows. Each connector endface ships with a protective dust cap and has been interferometrically inspected for geometry compliance—no scratch/dig defects, core apex offset within 50 µm, and radius-of-curvature held to 10-25 mm per IEC 61300-3-35. This eliminates the field-polish variability that causes intermittent link failures in 40G optics, where four parallel lanes push aggregate loss budgets below 2 dB. When you're deploying Cisco Nexus or Arista spine switches with MPO breakout modules, this duplex jumper completes the last-meter connection from breakout cassette LC ports to server NICs or ToR switch uplinks.

The 13-foot length bridges typical 42U rack heights with 6-foot service loops for future MAC work—long enough to route cleanly through overhead cable trays or underfloor ducts without mid-span slack management, short enough to avoid the 0.5 dB insertion-loss floor that 30-meter runs introduce through modal dispersion. The LSZH jacket meets UL 1666 riser rating and IEC 60332-3-24 flame propagation limits, required for installation above suspended ceilings in LEED-certified builds or anywhere local AHJ enforces NFPA 70 Article 770 plenum rules. Aqua is the sole TIA-compliant color for OM4 cable plant—mixing green OM3 and aqua OM4 jumpers on the same patch panel prevents the 40G transceiver compatibility errors that occur when 150-meter OM4 link budgets get violated by accidental OM3 substitution.

Panduit's LC connector uses a 1.25 mm ceramic ferrule with RoHS-compliant bronze split-sleeve alignment, captive in a composite housing that survives 500+ mating cycles per IEC 61754-20 without measurable insertion-loss drift. The duplex clip is TIA-604-10-B (FOCIS-10) compliant, locking into standard LC duplex receptacles on Cisco, Juniper, Brocade, or HP transceivers. The assembly ships with end-to-end polarity verification: Fiber A (transmit) on Position 1 maps to Fiber A (receive) on the far end Position 1, matching Method B patch-cord wiring per TIA-568.3-D Annex A. This is the default polarity for all duplex transceivers; you won't need crossover adapters or field re-termination unless you're interfacing with legacy Method A trunk cable that was mis-deployed without polarity documentation.
