Panduit FS2EPKELENEM008 OM4+ E-Key LC Fiber Cord 8m

Panduit FS2EPKELENEM008 Opti-Core™ 2-Fiber OM4+ Duplex LC Fiber Patch Cord with E-Code Keying - 8m

The Panduit FS2EPKELENEM008 is a high-performance 2-fiber OM4+ plenum-rated patch cord engineered for secure, high-density fiber installations where physical layer security and signal integrity are critical. Featuring Panduit's Signature Core™ technology and E-code keying on one end, this 8-meter duplex LC cord delivers ultra-low insertion loss while providing an additional layer of protection against unauthorized connections in datacenters, enterprise networks, and government facilities. The OFNP plenum rating ensures code compliance for installation in air handling spaces, and the 1.6mm zipcord jacket offers excellent flexibility for tight-radius routing in crowded patch panels and equipment racks.

Key Features

• E-Code Keying System — One end features coded duplex LC connector, the other uncoded LC, enabling secure keying strategies where coded patch cords mate only with matching coded adapters or equipment ports, preventing accidental or unauthorized cross-connections
• OM4+ Signature Core™ Technology — Panduit's enhanced OM4+ fiber exceeds standard OM4 performance with tighter modal bandwidth tolerances, delivering headroom for 40GBASE-SR4 at 150m and 100GBASE-SR4 at 100m with margin to spare
• Ultra-Low Insertion Loss — Factory-terminated and tested LC connectors deliver industry-leading insertion loss performance, maximizing link budget and ensuring reliable 10/40/100G transmission over longer distances
• Plenum-Rated OFNP Jacket — UL 910 plenum rating meets NEC Article 770 requirements for installation in air handling spaces without conduit, reducing installation cost and maintaining fire safety compliance
• 8-Meter Length — Ideal for rack-to-rack connections, cross-connects in equipment rooms, or longer patch panel runs where standard 1-3m cords fall short
• High-Density Duplex LC Form Factor — Industry-standard duplex LC connectors support twice the port density of SC, critical for maximizing faceplate and panel utilization in space-constrained installations

Panduit's Opti-Core™ OM4+ patch cords address a persistent challenge in modern datacenter and enterprise fiber deployments: how to maintain physical layer security without sacrificing performance or manageability. The E-code keying system works by color-coding and mechanically keying connectors and mating adapters — a coded connector will only insert into a matching coded adapter, preventing accidental misconnections between production and management networks, or between different security zones. The FS2EPKELENEM008 ships with one coded end (orange E-key) and one uncoded end, giving integrators flexibility to deploy keying at the equipment end while maintaining standard connectivity at the patch panel, or vice versa. This asymmetric design is particularly valuable in migration scenarios where legacy infrastructure remains uncoded but new equipment requires keying, or in hybrid environments where not all links demand the same security posture.

The Signature Core™ fiber technology delivers measurable performance advantages over commodity OM4 cable. While standard OM4 multimode fiber specifies 4700 MHz·km effective modal bandwidth at 850nm, Panduit's OM4+ consistently exceeds 5000 MHz·km, providing additional margin for 40G and 100G applications. This headroom translates to longer maximum reach, better BER performance at distance, and future-proofing against tighter loss budgets as active equipment evolves. For 10GBASE-SR links, the additional bandwidth allows operation beyond the 400m OM4 spec in many cases; for 40GBASE-SR4 and 100GBASE-SR4, it ensures reliable operation at the full 100-150m spec even in the presence of connector degradation, dust, or minor installation defects. The ultra-low insertion loss spec — typically below 0.15 dB per mated pair — compounds this advantage, often delivering 0.3-0.5 dB of additional link budget compared to standard OM4 assemblies.

The OFNP plenum rating is mandatory for installation in return air plenums, drop ceilings, and raised floors where building codes prohibit non-plenum cable. Panduit's plenum jacket uses low-smoke, flame-retardant materials that meet UL 910 Steiner Tunnel test requirements, ensuring the cable will not contribute to fire spread or produce toxic smoke in the event of a fire. The 1.6mm zipcord jacket construction — two individual 900µm buffered fibers in a flat, separable configuration — offers excellent flexibility and bend radius performance, making it easy to route through tight spaces, around corners, and into high-density LC panels without kinking or stressing the fiber. The orange jacket color follows TIA-598-D color coding for OM4 multimode fiber, providing instant visual identification and reducing the risk of mixing multimode and singlemode links during MAC work.

This 8-meter length is a practical choice for equipment room and datacenter applications where 1-3m patch cords are too short but 15-30m trunk cables are overkill. Common use cases include rack-to-rack connections within a row, cross-connects between network core and distribution switches, and SAN storage array connections where equipment is separated by 3-6 rack positions. The duplex LC connector is the de facto standard for 10/40/100G optical modules (SFP+, QSFP+, QSFP28), delivering twice the port density of SC or ST while maintaining compatibility with industry-standard LC adapters, panels, and enclosures. The RoHS-compliant construction meets environmental regulations for equipment deployed in the EU and other jurisdictions with hazardous substance restrictions, and Panduit's factory termination and testing ensures every cord ships with verified insertion loss and return loss performance, backed by test data and a comprehensive warranty.

The E-code keying system is part of Panduit's broader Color-Code Keying Solutions portfolio, which includes color-coded and mechanically keyed connectors, adapters, and modules in eight distinct key types (A through H). By standardizing on a keying scheme across patch cords, panels, and equipment connections, network operators can enforce segmentation policies at the physical layer — for example, assigning orange E-keyed cords to production VLANs, aqua A-keyed cords to management networks, and lime B-keyed cords to storage fabrics. This approach reduces human error during MAC operations, prevents costly misconfigurations, and adds a visible, tactile enforcement layer on top of logical network segmentation. The FS2EPKELENEM008's one-end-coded design is ideal for transitional deployments, boundary connections, or scenarios where one end of the link terminates at shared infrastructure (like a keyed equipment port) and the other at a standard patch panel.

Whether you're deploying a secure government network with physical layer access control, building out a high-performance 40G datacenter fabric, or simply need reliable 8-meter OM4+ plenum patch cords for a large enterprise equipment room, the Panduit FS2EPKELENEM008 delivers the performance, compliance, and keying flexibility required for mission-critical fiber infrastructure. Backed by Panduit's reputation for precision manufacturing and industry-leading warranty coverage, this cord represents a proven, field-tested solution for demanding multimode fiber applications.
