Panduit FS2EPKGLGNGM005 Opti-Core OM4+ G-Coded Fiber Patch Cord

The Panduit FS2EPKGLGNGM005 is a 2-fiber OM4+ Signature Core duplex patch cord engineered for high-density data center and enterprise network environments demanding maximum bandwidth, physical layer security, and plenum-rated flame performance. This 5-meter (16.4 ft) jumper features G-coded duplex LC connectors on one end and standard duplex LC on the other, enabling secure, keyed connections that prevent unauthorized equipment access or accidental cross-connections. The violet 1.6mm zipcord jacket meets OFNP plenum specifications for installation in air-handling spaces, while ultra-low insertion loss ensures headroom for 10GBASE-SR, 40GBASE-SR4, and 100GBASE-SR10 links across the full channel.

Key Features

• OM4+ Signature Core fiber — higher bandwidth ceiling than standard OM4 for future-ready 40/100G deployments
• G-coded duplex LC on one end — physical keying prevents misplugs; pairs only with matching G-coded components
• Ultra-low insertion loss — tighter tolerance than industry baseline conserves loss budget in multi-span links
• Plenum-rated OFNP jacket — meets NEC Article 770 for installation in air-handling ceilings and raised floors
• 5-meter length — ideal for rack-to-rack, cabinet-to-cabinet, or cross-aisle data center runs
• 1.6mm zipcord construction — lies flat in tight pathways, easier routing than round cordage in high-density panels
• Standard duplex LC termination on opposite end — connects to switches, servers, or non-coded infrastructure without adapters
• Violet jacket — OM4 standard color coding for instant fiber-type identification during moves-adds-changes

OM4+ Signature Core technology extends the performance envelope of laser-optimized 50/125µm multimode fiber. Where standard OM4 supports 10G to 550 meters and 40/100G to 150 meters, Signature Core delivers lower modal dispersion and tighter core geometry tolerances, increasing effective bandwidth-distance product. In practice, this means margin for longer campus backbone runs, additional connector pairs in the channel, or sustained performance as transceivers age and launch conditions drift. The ultra-low insertion loss specification — tighter than the 0.75dB maximum required by TIA-568 — is critical in 40G and 100G parallel optics deployments where eight or more fibers carry a single data stream; every 0.1dB saved per connector pair translates to extended reach or tolerance for future splices. The G-coded LC connector system adds a mechanical key profile to the duplex clip, creating a physical barrier against unauthorized patch changes or inadvertent cross-connections between production and test networks. In environments with compliance mandates — financial trading floors, healthcare HIPAA zones, or government FISMA installations — G-coding provides a visible, tactile enforcement layer that survives user error and social-engineering attempts. One end remains standard LC for connection to switch ports or server NICs; the other end's G-coded profile mates only with G-coded bulkhead adapters or patch panels, creating a secure perimeter at the structured cabling layer.

The 5-meter length is purpose-built for intra-rack and inter-rack connections in modern data centers where top-of-rack switches sit 6-12U below the cable management tray and adjacent racks are spaced 1-2 meters apart. Shorter jumpers create tension; longer jumpers waste space and add unnecessary insertion loss through excess fiber coiling. The 1.6mm zipcord jacket — two 0.9mm tight-buffered fibers in a flat, figure-eight cross-section — lies flat against vertical managers and threads through horizontal fingers without the springy memory of round 2mm zip cord or 3mm distribution cable. This matters in 48-port duplex LC panels where 96 fibers must route through a 1U space; flat zipcord reduces bundle diameter by 30-40% compared to round alternatives. The OFNP plenum rating is non-negotiable in most commercial installations: national and local electrical codes require plenum-rated cable in any space used for environmental air circulation, including drop ceilings, raised floors, and HVAC plenums. OFNP-rated constructions use low-smoke, flame-retardant jacket compounds that self-extinguish and emit minimal toxic gas during fire, protecting both occupants and first responders. Installers working under NEC Article 770 or IBC Section 2610 can route this cordage freely without fire-stopping or conduit, streamlining MAC work and reducing labor cost per connection.

The FS2EPKGLGNGM005 ships with factory-terminated, factory-tested LC connectors on both ends, eliminating field termination labor and the risk of contamination or end-face damage during installation. Each jumper is individually bagged and serialized, with insertion loss and return loss test data available on request for critical links requiring as-built documentation. This patch cord integrates seamlessly into Panduit's broader Opti-Core infrastructure — pair it with G-coded LC cassettes, breakout panels, and trunk assemblies to build a end-to-end coded backbone that extends physical security from the main distribution area to every server rack. For integrators managing converged IP surveillance, access control, and IT networks on a single fabric, G-coding provides segmentation that survives the human factors and operational pressures of 24/7 NOC environments, ensuring that camera uplink traffic stays isolated from guest Wi-Fi or that building automation VLANs remain distinct from POS systems even when technicians are working under time constraints or inadequate lighting.
