Panduit FS2EPKFKFNFM010 Opti-Core 2-Fiber OM4+ Keyed LC Duplex Patch Cord

When you're patching high-bandwidth security backbones or datacenter aggregation switches, a single mis-terminated fiber strand can cost hours of troubleshooting or compromise network segmentation. Panduit's FS2EPKFKFNFM010 solves that with keyed LC duplex connectors—physically coded adapters and plugs (F-code, dark blue) that mate only with matching keyed components. This 10-meter OM4+ Signature Core duplex patch cord delivers ultra-low insertion loss for 40G/100G links, ships with OFNP plenum rating for air-handling spaces, and integrates into Panduit's color-and-key cabling system to add a physical layer of security against accidental or unauthorized cross-connections.

Key Features

Keyed LC duplex connectors (F-code, dark blue) on both ends—mates only with matching F-keyed adapters to prevent mis-patching

OM4+ Signature Core fiber with ultra-low insertion loss—optimized for 40GBASE-SR4, 100GBASE-SR4, and extended-reach 10G links

10-meter (32.81 ft) length—ideal for rack-to-rack or intra-row patch panel connections in datacenter or NOC environments

OFNP plenum rating—UL listed for installation in air-handling spaces without conduit

1.6mm zipcord jacket—flexible, easy to dress in high-density cable managers, dark blue outer jacket for visual F-code identification

RoHS compliant—meets European Union hazardous-substance directives for safe deployment and disposal

Panduit's Opti-Core keyed connector system uses molded plastic keys on both the LC duplex plug and the adapter insert. Each key profile (A through L) represents a unique physical geometry—F-code keys will not insert into a G-code or H-code adapter, and vice versa. This prevents the most common fiber troubleshooting disaster: accidentally swapping Tx/Rx pairs or cross-patching to the wrong port in a dense 96-fiber panel. The FS2EPKFKFNFM010 ships with F-code (dark blue) keys factory-installed on both duplex LC connectors, so you simply order matching F-keyed panel adapters and your entire zone—say, all security camera uplinks to a core switch—becomes mechanically isolated from adjacent zones. Insertion loss on Signature Core OM4+ fiber typically measures under 0.2 dB per mated pair, and the low-profile duplex LC footprint supports up to 144 fibers in a single rack unit when used with Panduit's high-density adapter panels.

OM4+ cable extends the bandwidth-distance envelope of standard OM4 multimode fiber, supporting 100GBASE-SR4 over 150 meters (versus 100m for OM3) and enabling 40G links beyond 400 meters with parallel optics. In a surveillance datacenter or access-control NOC, that translates to flexibility when you're aggregating IP camera VLANs onto 40G uplinks or building redundant storage-area-network paths between NVR clusters and SAN arrays. The OFNP plenum jacket meets NEC Article 770 requirements for cables installed above drop ceilings or in HVAC plenums without metal conduit—critical for retrofits in commercial buildings where running conduit adds weeks and tens of thousands of dollars to the labor budget. The 1.6mm zipcord construction splits easily at the breakout point (versus round-jacket cable, which requires a slitting tool), and the smaller diameter reduces bundle fill in vertical cable managers when you're dressing dozens of patch cords in a 42U rack.

The keyed-connector advantage shows up most clearly in multi-tenant datacenter colocation or secure-access installations where physical layer isolation matters as much as logical VLAN segmentation. Assigning F-code (dark blue) to all law-enforcement access-control uplinks, G-code (violet) to building-services cameras, and H-code (yellow) to guest Wi-Fi backhaul means a technician cannot accidentally patch a guest-network switch into the evidence-storage SAN—the plug will not fit the adapter. Panduit supplies matching keyed adapter inserts (sold separately) for all standard LC patch panels, so you retrofit existing infrastructure by swapping non-keyed inserts for keyed inserts in the same footprint. This FS2EPKFKFNFM010 patch cord integrates immediately into that system, ships in cartons of 10 for volume deployment, and carries Panduit's standard manufacturer warranty covering materials and workmanship.
