Panduit FS2EPKDLDNDM005 Opti-Core™ OM4+ 2-Fiber D-Coded Duplex LC Patch Cord

The Panduit FS2EPKDLDNDM005 delivers OM4+ Signature Core™ performance with integrated physical layer security for mission-critical datacenter and network infrastructure. This 5-meter plenum-rated patch cord features D-coded duplex LC on one end and standard duplex LC on the other, enabling secure, keyed connections that prevent unauthorized cable swaps or accidental mismatches. Ultra-low insertion loss and OM4+ bandwidth support 40/100G Ethernet applications up to 150 meters, making it ideal for spine-leaf architectures, SAN storage fabrics, and high-density switch interconnects where performance and security cannot be compromised.

Key Features

OM4+ Signature Core™ fiber — enhanced bandwidth over standard OM4, supporting 40GBASE-SR4 and 100GBASE-SR4 with extended reach and lower attenuation

D-coded physical security — one end keyed with D-code LC connector; pairs only with matching D-coded receptacles to prevent unauthorized access or cable theft

Ultra-low insertion loss — factory-terminated and tested to ensure minimal signal degradation across the link

Plenum rated (OFNP) — meets NEC 770 requirements for air-handling spaces; low smoke, flame-retardant jacket for code compliance

1.6mm zipcord jacket — flexible, durable construction for tight-radius routing in cable managers and patch panels

5-meter length — 16.4 feet provides reach for cross-rack patching or floor-to-floor vertical runs in raised-floor datacenters

OM4+ Signature Core™ fiber uses tighter manufacturing tolerances and optimized core geometry to deliver lower modal dispersion than standard OM4 multimode fiber. This translates to longer reach at 40G and 100G speeds—critical when designing spine-leaf topologies or extending SAN fabrics across multiple rows. The FS2EPKDLDNDM005's ultra-low insertion loss (typically below 0.2 dB) preserves link budget, reducing the need for additional attenuation margin and enabling more reliable operation near the edge of IEEE 802.3 distance specifications. For installations running 10GBASE-SR or 25GBASE-SR, OM4+ extends reach to 400+ meters, well beyond standard OM3 capabilities, future-proofing the physical layer for eventual migration to higher speeds.

The D-coded LC connector on one end integrates with Panduit's Opti-Core™ coded cabling system, which pairs connectors and adapters by mechanical key. In multi-tenant datacenters, financial services environments, or defense installations where physical layer security is mandated, D-coding prevents opportunistic cable swaps and ensures that only authorized technicians with matching keyed adapters can reconfigure circuits. The non-coded end terminates standard duplex LC, allowing connection to legacy switch ports or non-coded patch panels during migration phases. Plenum rating (OFNP) satisfies NEC Article 770 for installation in return-air plenums, overhead cable trays, and suspended ceiling spaces without conduit—streamlining deployments in commercial buildings where AHJ inspection is required. The 1.6mm zipcord jacket offers the flexibility needed for dense patch panel dressing while maintaining jacket integrity during repeated moves, adds, and changes.
