Panduit FS2EPKFLFNFM010 Opti-Core™ OM4+ Keyed LC Duplex Fiber Patch Cord
Panduit's FS2EPKFLFNFM010 delivers OM4+ Signature Core™ fiber performance in a 10-meter plenum-rated patch cord engineered for high-density datacenter and enterprise backbone deployments. One end terminates in a keyed LC duplex connector (F-key, dark blue), the other in standard LC duplex—giving you physical-layer security at the patch panel while maintaining backward compatibility at the equipment end. Specify this cord when your installation requires 40/100GBASE-SR4 headroom, air-plenum compliance, and a keyed connection strategy that prevents unauthorized or accidental cross-connects.
Key Features
- OM4+ Signature Core™ fiber — tighter modal bandwidth than standard OM4; supports 100GBASE-SR4 to 125 m and 40GBASE-SR4 to 150 m (vs. 100 m and 125 m for OM4)
- Keyed LC on one end, standard LC on the other — F-key coding locks into mating F-key adapters at the patch panel, preventing plug-in mistakes; non-keyed end connects to switch/server ports without adapter changes
- Ultra-low insertion loss — Panduit factory termination and Signature Core geometry deliver <0.15 dB typical IL, preserving link budget on long campus runs or multi-tier spine-leaf fabrics
- Plenum rated (OFNP) — UL 910 / NFPA 262 certified for installation in air-handling spaces, above drop ceilings, and horizontal pathways without conduit
- 1.6 mm zipcord jacket — flexible, low-profile dual-fiber construction simplifies high-density cable management and reduces pathway congestion
- 10-meter length — ideal for cross-rack connections, row-to-row links, or distribution-frame-to-equipment runs in larger network closets and datacenter pods
Panduit's Signature Core™ fiber uses a parabolic index profile and tighter manufacturing tolerances to push modal bandwidth beyond the OM4 minimum (4700 MHz·km at 850 nm). The result is measurably lower differential mode delay, which translates to longer 40G and 100G reach and greater margin on parallel-optic transceivers. When you're planning a 40GBASE-SR4 or 100GBASE-SR4 deployment with future 200G/400G migration in mind, OM4+ gives you an extra 20–25 m of reach per link—enough to bridge an additional row of racks or skip a tier of distribution switches. The F-key connector system (color-coded dark blue) is part of Panduit's physical-layer security portfolio: keyed connectors mate only with keyed adapters that share the same key type, so accidental cross-patching between VLANs, tenants, or security zones becomes mechanically impossible. You'll typically deploy keyed cords from the patch panel (where you install keyed adapters) to non-keyed equipment ports, giving you a one-way physical enforcer at the aggregation point while preserving standard LC compatibility at the server or switch.
The OFNP (plenum) rating means the jacket compound meets UL 910 flame and smoke limits, so you can route this cord through HVAC plenums, above-ceiling return-air pathways, and raised-floor distribution without metallic conduit. Most datacenter hot-aisle containment and overhead cable-tray designs mandate plenum-rated cords; OFNP satisfies that requirement and keeps you code-compliant during inspections. The 1.6 mm zipcord construction (two 900 µm tight-buffered fibers in a figure-eight jacket) is more flexible and takes up less vertical manager space than round 2 mm cordage, which matters when you're dressing 96-fiber trunk breakouts or managing dozens of server NICs in a single 42U cabinet. At 10 meters, this cord length covers typical intra-row and cross-row distances in a pod architecture—long enough to reach from a spine switch at one end of the row to a leaf switch three racks down, short enough to avoid excess service loop that clutters pathways and creates bend-radius hazards.
Panduit ships every Opti-Core cord with individual IL and RL test data serialized to the pull tab; you can scan the tag and upload results to your DCIM or cable-management database for as-built documentation and future troubleshooting. The dual LC connectors use ceramic ferrules, pre-polished to <50 nm apex offset, and the duplex clip is TIA-604-10-compliant (FOCIS-10), so the cord mates reliably with any standards-based LC adapter—Panduit, third-party, or OEM transceiver pigtails. RoHS compliance (lead-free, low-halogen jacket) satisfies procurement requirements for enterprise IT and government contracts. When your project calls for OM4+ performance, plenum safety, keyed security, and a length that bridges distribution frames to active equipment without excessive slack, the FS2EPKFLFNFM010 is the engineered answer—factory-terminated, serialized, and ready to install.
