Panduit FS2EPKDLDNDM010 Opti-Core OM4+ Fiber Patch Cord
The Panduit FS2EPKDLDNDM010 is a 10-meter duplex LC fiber optic patch cord engineered for high-density datacenter and enterprise installations requiring physical-layer security. Built on Signature Core OM4+ multimode fiber, this 2-fiber jumper delivers ultra-low insertion loss for 40G/100G Ethernet links while meeting OFNP plenum flame ratings for in-ceiling and raised-floor pathways. One end features Panduit's D-code keyed LC connector (yellow) that physically prevents unauthorized cross-connects; the other end terminates in a standard non-keyed yellow LC duplex. Integrators deploying secure network segmentation—financial trading floors, healthcare records systems, defense installations—gain an additional authentication layer beyond logical access controls.
Key Features
- OM4+ Signature Core multimode fiber: 50/125μm core optimized for 40GBASE-SR4 (150m), 100GBASE-SR10 (150m), and legacy 10G applications (550m)
- D-code physical security: keyed LC connector at one end mates only with D-code adapters, blocking unauthorized patch changes in secure zones
- OFNP plenum rating: NEC Article 770 compliant for air-handling spaces without conduit, self-extinguishing jacket reduces flame-spread risk
- Ultra-low insertion loss: factory-terminated with <0.15 dB typical IL, <0.25 dB max, preserving link budget in multi-tier spine-leaf topologies
- 1.6mm zipcord jacket: flexible dual-cable construction simplifies pulling through congested overhead cable trays and patch-panel dressing
- 10-meter reach: spans adjacent racks (up to 32 feet), intra-row switches, or top-of-rack to middle-of-rack server connections
Panduit's Signature Core manufacturing process polishes each ferrule to sub-micron tolerances and end-face geometries that exceed TIA-568.3-D requirements. The result is consistent sub-0.15 dB insertion loss across production runs—critical when link budgets are tight in 40G/100G deployments. OM4+ fiber extends effective modal bandwidth to 5,500 MHz·km at 850nm (versus 4,700 MHz·km for standard OM4), providing headroom for next-generation 200G/400G optics without re-cabling. Yellow jacket color follows TIA-598-C convention for OM4/OM4+ identification, and the aqua-core fiber is backward-compatible with OM3 and OM4 links when mixed-mode operation is required during phased upgrades.
The D-code keying system uses a mechanical tab-and-slot interface molded into the LC connector body. Standard LC patch cords cannot physically insert into D-code adapters, and D-code plugs cannot insert into standard adapters—creating an air-gap enforcement mechanism for network segmentation policies. In environments where physical access is regulated (SOC 2 datacenters, FISMA Moderate systems, PCI DSS cardholder environments), D-code patch cords reduce the risk of accidental or malicious cross-connections between production and non-production VLANs. One end of this jumper is keyed (D-code yellow LC), the other end is non-keyed (standard yellow LC)—allowing integrators to deploy D-code protection at the secure-side patch panel while maintaining standard LC interfaces at switches or servers that don't require keying.
OFNP (Optical Fiber Nonconductive Plenum) rating meets NEC 770.179(A) for installation in ducts, plenums, and other air-handling spaces. The low-smoke zero-halogen jacket self-extinguishes and resists flame propagation per UL 910 (Steiner Tunnel Test), satisfying building inspector requirements in commercial high-rises and healthcare facilities. The 1.6mm zipcord construction—two individually jacketed 900μm tight-buffered fibers in a side-by-side configuration—provides bend-radius flexibility (10× cable diameter minimum bend) that simplifies routing through high-density patch panels where dozens of jumpers converge in a 1U space. Installers gain the stiffness needed for push-through overhead J-hooks without the rigidity that causes kinking at sharp panel turns.
This patch cord ships as a single unit (package quantity 1) and is sold in cartons of 10 for volume deployments. Panduit Opti-Core fiber systems are RoHS-compliant and backed by manufacturer warranty. Integrators building secure 40G/100G networks for financial services, government, or multi-tenant datacenters should evaluate D-code keyed infrastructure as part of their physical-layer defense strategy—this 10-meter jumper closes the gap between policy-enforced segmentation and physical air-gap enforcement at the patch panel.
