Panduit FS2EPKDKDNDM010 Opti-Core OM4+ Keyed Fiber Patch Cord

The Panduit FS2EPKDKDNDM010 is a 10-meter duplex fiber patch cord built with OM4+ Signature Core fiber and D-code keyed LC connectors for installations requiring physical layer security. OFNP plenum-rated construction meets IBC Chapter 8 requirements for air-handling spaces. Ultra-low insertion loss and OM4+ performance support 40GBASE-SR4 to 150 meters and 100GBASE-SR4 to 100 meters over multimode fiber. Yellow jacket and yellow keyed connectors enable rapid polarity verification in dense patch fields.

Key Features

• OM4+ Signature Core fiber delivers lower attenuation than ISO/IEC 11801 OM4 requirements—supports extended reach for 40G/100G applications
• D-code keyed duplex LC connectors prevent mating with non-keyed or differently-keyed adapters, reducing misconfiguration risk in multi-tenant or secure facilities
• OFNP plenum rating (cámara impelente) qualifies for installation above suspended ceilings and in HVAC plenums per NEC Article 770
• Ultra-low insertion loss specification ensures margin headroom on 40/100G links where 0.5 dB can determine pass/fail on channel testing
• 1.6 mm zipcord cable construction with yellow jacket provides flexibility for tight-radius routing in rack cable managers and patch panel dressings
• Duplex LC-to-LC configuration with 10-meter (32.8 ft) length suits cross-row connections in data centers or MDF-to-IDF runs in enterprise buildings
• Part of Panduit's keyed fiber system—mates only with D-code adapters and cassettes, creating isolated color-coded infrastructure layers

Panduit's Signature Core OM4+ fiber uses tighter manufacturing tolerances on core diameter and numerical aperture to achieve lower modal dispersion than standard OM4 (3.0 dB/km max attenuation at 850 nm vs. 3.5 dB/km for baseline OM4). This translates to 15–20% longer reach on 40GBASE-SR4 and 100GBASE-SR4 links, critical when aggregating 10G uplinks into 40G spines or 100G core switches. Insertion loss is specified at ≤0.35 dB per mated connector pair, leaving sufficient link budget for four-connector channels (two patch cords plus permanent link) to stay below the 1.5 dB IEEE 802.3ba allocation. The LC connector ferrules are factory-terminated and inspected, eliminating field-polishing variables that cause high loss or back-reflection on job-site terminations. Return loss exceeds 20 dB, preventing reflection-induced BER degradation on parallel optics transceivers.

The D-code keyed connector system uses a mechanical key profile molded into the LC connector housing that aligns with a corresponding slot in keyed adapters and cassette modules. Attempting to insert a non-keyed plug or a plug with a different key code (A, B, C, etc.) into a D-code adapter physically blocks insertion, stopping accidental cross-connections between production and backup networks, or between tenant A and tenant B in colocation facilities. Yellow cable jacket and yellow connector boots match Panduit's standard OM4 color convention, but the keyed mechanism adds a layer of physical enforcement beyond color alone—useful when installers are working under time pressure or in low-light conditions. The 10-meter length covers typical cross-aisle distances in data centers (rack-to-rack or end-of-row switch to middle-of-row server) and horizontal-to-vertical cable manager transitions in telco rooms. OFNP plenum rating qualifies the cable for installation in spaces used for environmental air circulation per NEC 770.113(A), avoiding costly plenum-rated conduit or the need to re-pull cables during fire marshal inspections.

This patch cord integrates with Panduit's FZ cassette modules, keyed adapter panels, and Opti-Core trunk cables to build a color-and-key segregated fiber plant. Data centers running multi-tenant or classified/unclassified networks use the keying system to enforce separation at the physical layer, satisfying SSAE 18 SOC 2 controls or NIST SP 800-53 access-control requirements without relying solely on procedural discipline. The 1.6 mm zipcord construction allows the two fibers to split for breakout applications while maintaining a compact cross-section for high-density 1U horizontal cable managers.
