Panduit FS2EPKDKDNDM020 Opti-Core™ OM4+ 2-Fiber D-Code Plenum Patch Cord

Panduit's FS2EPKDKDNDM020 delivers 20 meters of OM4+ Signature Core™ duplex fiber in a keyed, color-coded configuration designed for high-speed datacenter and enterprise networks where physical layer security and 40/100GBASE-SR4 performance are non-negotiable. The D-code duplex LC connectors ensure connection integrity by preventing cross-mating with incompatible fiber types, while the plenum-rated (OFNP) zipcord jacket meets NEC Article 770 requirements for air-handling spaces. Ideal for cross-connect applications between main distribution areas and intermediate frames, or extended equipment runs where standard 3-5 meter patch cords fall short, this 65.6-foot cord eliminates the need for mid-span splicing while maintaining ultra-low insertion loss across the link.

Key Features

• OM4+ Signature Core Fiber – Enhanced OM4 supports 40GBASE-SR4 to 150m and 100GBASE-SR4 to 100m, exceeding standard OM4 reach by 50% for 40G links
• D-Code Keyed LC Duplex Connectors – Color-coded yellow housings with physical keying prevent insertion into non-OM4+ ports, eliminating accidental cross-connections that degrade link performance
• Plenum Rated (OFNP) – Cámara impelente jacket meets NEC Article 770.179 for installation in air-handling spaces without additional conduit
• Ultra-Low Insertion Loss – Factory-terminated and tested connectors deliver <0.35dB typical IL, critical for multi-hop datacenter fabrics and tight 100G optics loss budgets
• 20-Meter Extended Reach – 65.6-foot length bridges MDA-to-IDF cross-connects or equipment racks separated by hot/cold aisle layouts without mid-span splicing
• Zipcord Round Jacket Construction – 1.6mm dual-fiber round cable routes more easily through cable managers and tight bend radii than breakout-style cords
• Yellow Jacket + Connector Boots – Full-length color coding simplifies fiber type identification during moves/adds/changes in dense patch panel environments

Panduit's Opti-Core system combines OM4+ multimode fiber—manufactured to tighter tolerances than TIA-492-AAAD baseline OM4—with bend-insensitive Signature Core technology that maintains performance through the 7.5mm bend radii common in high-density patch panels. The FS2EPKDKDNDM020's D-code keying system adds a physical security layer often mandated in government, financial, and healthcare datacenters: the yellow D-key connector bodies mate only with D-keyed adapters, preventing installers from accidentally patching OM4+ links into OM3 (aqua, no key) or single-mode (blue, different key profile) infrastructure. This color-and-key combination reduces human error during 2 a.m. emergency failovers and ensures 40G/100G SR4 optics see the correct fiber type end-to-end. At 20 meters, this cord length addresses the gap between standard 3-5m equipment patch cords and the 30m+ trunk cables typically used for building risers—ideal for horizontal cross-connects in raised-floor datacenters where patch panels sit 15-20 meters from the aggregation switch stack, or for securing IP cameras and access controllers in enterprise campuses where fiber runs extend across equipment rooms.

The OFNP plenum rating uses a low-smoke, halogen-free jacket compound that self-extinguishes and produces minimal smoke during fire exposure, meeting the flame-spread and smoke-density tests in NFPA 262 (UL 910). This rating is required for any cable installed in plenums, ducts, or other air-handling spaces per NEC 770.179(A), eliminating the need for expensive enclosed conduit in above-ceiling runs. Installers can route the FS2EPKDKDNDM020 directly through cable trays in plenum spaces, reducing material cost and installation time on new builds and retrofits. The 1.6mm zipcord jacket—two buffered fibers in a single round extrusion—offers better flexibility and smaller bend radius than twin-cable breakout designs, simplifying dense patch panel dressing and reducing the footprint in crowded cable managers. Each connector is factory-terminated with Panduit's automated polishing process, delivering insertion loss consistently below 0.35dB and return loss >35dB, ensuring margin for the 1.5-1.9dB loss budgets typical of 100GBASE-SR4 links using MPO-to-LC breakout modules.

The FS2EPKDKDNDM020 ships as a single cord (10 per carton for volume orders) and meets RoHS directives for lead-free, environmentally responsible deployment. For integrators building out 40G/100G spine-leaf fabrics, securing high-bandwidth IP surveillance backhaul, or future-proofing enterprise LANs for 400G migration, this 20-meter OM4+ D-code cord provides the reach, performance, and physical layer assurance required when standard patch cord lengths don't span the distance and mid-run splicing introduces unacceptable loss and failure points.
