Panduit FS2EPKFKFNFM008 8m OM4+ Coded LC Duplex Cord

Panduit FS2EPKFKFNFM008 Opti-Core™ OM4+ Coded Fiber Patch Cord

Panduit's FS2EPKFKFNFM008 delivers enterprise-grade fiber connectivity with an added layer of physical security through keyed connector technology. This 8-meter (26.25 ft) duplex patch cord features Signature Core™ OM4+ fiber terminated with dark-blue coded LC connectors at both ends, ensuring that patches can only be made between matching coded components. Rated for plenum spaces (OFNP), it meets stringent building and fire codes for air-handling installations in datacenters, server rooms, and enterprise network cores. The 2-fiber duplex design with 1.6mm zipcord jacket provides the flexibility installers need for tight-radius routing in high-density racks while maintaining ultra-low insertion loss for 40GBASE-SR4 and 100GBASE-SR4 applications.

Key Features

• Signature Core™ OM4+ multimode fiber — engineered for 40G/100G Ethernet over extended distances with lower attenuation than standard OM4
• Keyed LC duplex connectors (F-code, dark blue) — physical layer security prevents unauthorized or accidental cross-connects in mission-critical environments
• OFNP plenum rating — meets NEC Article 770 requirements for installation in air-handling spaces without additional conduit
• Ultra-low insertion loss — factory-terminated and tested to ensure optimal link budgets and headroom for future upgrades
• 1.6mm zipcord jacket — dark blue outer sheath allows easy visual identification while providing flexibility for dense patch panel routing
• 8-meter (26.25 ft) length — ideal for cross-rack connections, network core aggregation, or datacenter row-to-row fiber runs
• RoHS compliant — meets EU directives for hazardous substance restrictions in electronic equipment

The Opti-Core coded connector system addresses a persistent challenge in secure and regulated network environments: ensuring that fiber patches are made only where authorized. Traditional LC connectors are universal—any LC plug fits any LC jack—but Panduit's keyed design uses precision-molded locking tabs and receptacle slots that enforce physical compatibility. The F-code pattern on the FS2EPKFKFNFM008 matches only other F-coded components (adapters, cassettes, panels), making it impossible to mistakenly or maliciously connect this cord to a non-matching port. For government installations subject to DISA STIGs, financial datacenters with PCI-DSS audit requirements, or healthcare networks under HIPAA scrutiny, this mechanical enforcement layer complements logical access controls. Dark blue is the standard color code for OM4+ in the Opti-Core family, providing instant visual confirmation of fiber type during moves, adds, and changes.

Signature Core OM4+ fiber represents Panduit's enhanced-performance variant of standard OM4 multimode. Where legacy OM4 supports 40GBASE-SR4 to 150 meters and 100GBASE-SR10 to 100 meters, Signature Core OM4+ extends those distances and improves modal bandwidth, giving network architects greater margin in link design. This is critical when accounting for connector loss, splice loss, and the cumulative attenuation of multiple patch points in a structured cabling system. The ultra-low insertion loss specification—achieved through precision ferrule polishing and factory inspection—means each connection contributes minimal dB penalty, preserving optical power budget for longer spans or additional in-line components like fiber TAPs or monitoring splitters. For datacenter operators planning 400G migrations using parallel optics breakout strategies, starting with OM4+ infrastructure today reduces the risk of needing to re-pull fiber during future upgrades.

The OFNP (Optical Fiber Nonconductive Plenum) flame rating is mandatory for any cable installed in return-air plenums, raised floors, or drop ceilings that serve as environmental air pathways. These spaces, defined by NEC Article 770, require cables that meet strict smoke and flame-spread performance under NFPA 262 testing. The FS2EPKFKFNFM008's plenum-rated jacket ensures code compliance for installations in office buildings, hospitals, universities, and commercial facilities where avoiding conduit saves time and cost. The 1.6mm zipcord construction—a flat, two-fiber design—allows the cable to bend tightly around vertical cable managers and route through crowded horizontal pathways without kinking. This is especially valuable in 1U and 2U switch environments where every millimeter of bend radius matters, or in blade-server chassis backplane connections where space is at an absolute premium.

At 8 meters, this patch cord length suits cross-rack aggregation scenarios where distribution switches in adjacent racks connect to a core switch, or where storage arrays in one cabinet link to SAN switches two or three racks away. It's also the right length for top-of-rack to end-of-row fiber runs in hot-aisle/cold-aisle layouts, or for connecting network equipment mounted in overhead cable trays to floor-mounted patch panels. Unlike copper, fiber is immune to electromagnetic interference, making it the preferred choice for runs near high-voltage UPS systems, motor drives, or RF equipment. The dark blue jacket provides at-a-glance differentiation from OM3 (aqua), single-mode OS2 (yellow), or copper (various colors), reducing troubleshooting time during outages and simplifying MAC workflows when technicians are working under pressure.

Panduit's factory termination and testing process ensures that every FS2EPKFKFNFM008 ships with a test report verifying insertion loss, return loss, and endface geometry per IEC 61300-3-35. This eliminates the variability and field-termination errors common with on-site connectorization, where dust, improper cleaving, or inconsistent polishing can introduce loss spikes or back-reflection that degrade link performance. For installers bidding on enterprise or government projects with strict acceptance testing requirements, factory cords provide a known-good baseline and reduce the risk of failed certification runs. The coded LC interface is backward-compatible with standard LC cleaning tools and inspection microscopes, so existing fiber maintenance procedures remain unchanged—only the mating mechanical interface enforces the security policy.

This patch cord ships individually packaged (carton quantity: 10), making it straightforward to order exact quantities for phased datacenter builds or refresh projects where you need a few cords now and additional stock later without over-committing to bulk reels. RoHS compliance ensures that the materials meet European Union directives on lead, mercury, cadmium, and other restricted substances, which is increasingly a requirement for multinational enterprises with global purchasing standards or public-sector buyers in California and other states with equivalent environmental regulations. The UPC 61305686549 ties directly to Panduit's product catalog, simplifying procurement workflows and ensuring that replacement orders match the original specification without ambiguity.
