Panduit FS2EPKGLGNGM008 OM4+ 8m LC Patch Cord G-Code

Panduit FS2EPKGLGNGM008 Opti-Core™ OM4+ 2-Fiber LC Duplex Patch Cord with G-Code

The Panduit FS2EPKGLGNGM008 is an 8-meter OM4+ fiber optic patch cord engineered for high-speed data center and enterprise backbone applications requiring physical layer security. This duplex LC jumper features Signature Core™ OM4+ multimode fiber optimized for 40GBASE-SR4 and 100GBASE-SR10 at extended distances, with one end terminated in G-code violet LC connectors and the other in standard violet LC connectors. The plenum-rated (OFNP) zipcord jacket qualifies it for installation in air-handling spaces above drop ceilings and under raised floors without additional conduit, while the keyed connector system prevents unauthorized cross-connections in secure or mission-critical environments.

Key Features

• OM4+ Signature Core™ 50/125µm multimode fiber delivers 40G/100G performance with margin for longer spans and future 200G/400G migration
• G-code violet duplex LC on one end pairs only with matching G-code adapters, creating a physical security barrier against accidental or intentional mispatching
• Ultra-low insertion loss (typically <0.15 dB) and return loss >-40 dB ensure link budget headroom for high-speed optics and longer channel reaches
• Plenum-rated OFNP jacket meets NEC Article 770 for unrestricted installation in air-handling spaces, eliminating the need for metallic conduit in ceiling voids
• 8-meter (26.25 ft) length bridges cross-connect fields, patch panels, and equipment racks in medium to large telco rooms and data centers
• Zipcord 1.6mm cable construction provides flexibility for tight bend radii in high-density patch fields while maintaining jacket integrity
• Factory-terminated and tested LC connectors eliminate field polish variability and deliver consistent sub-0.2 dB insertion loss out of the box
• Violet jacket color per TIA-568 standard instantly identifies OM4 fiber type during moves, adds, and changes

OM4+ fiber extends standard OM4's 40GBASE-SR4 reach from 150m to 200m and 100GBASE-SR10 from 100m to 150m by tightening modal bandwidth and attenuation specifications. Panduit's Signature Core manufacturing process centers the core precisely within the 125µm cladding and optimizes the refractive index profile for 850nm VCSEL transceivers, reducing differential mode delay that limits channel distance. For integrators designing 40G/100G spine-leaf fabrics or storage area networks, this margin translates to fewer fiber strands per link (you can often use duplex LC instead of 8-fiber or 12-fiber MPO breakouts for shorter runs) and simpler troubleshooting when insertion loss budgets are tight. The G-code keying system physically alters the LC connector body profile so it mates only with G-code adapters and bulkheads; attempting to insert a G-code plug into a standard adapter or vice versa is mechanically blocked. This prevents well-intentioned but unauthorized cable swaps in classified networks, financial trading floors, or any environment where an incorrect cross-connect could bypass security zones or create a data exfiltration path.

The OFNP plenum rating qualifies this jumper for installation in the spaces above suspended ceilings and below raised floors that serve as return-air plenums in commercial HVAC systems. NEC Article 770.113 mandates plenum-rated cable in these areas because a fire in the plenum can spread smoke and toxic fumes throughout the building via the air distribution system; OFNP jackets are formulated to resist flame spread and limit smoke generation under NFPA 262 test conditions. For data center and enterprise campus deployments, this means you can run the FS2EPKGLGNGM008 from a ceiling-mounted cable tray down to a top-of-rack switch or from an underfloor pathway up to a floor-mounted rack without enclosing it in EMT conduit, saving material cost and installation labor. The 8-meter length suits horizontal cross-connects in telco rooms, connections between adjacent rows in co-location cages, or backbone links in split-core data center designs where your spine switches are ceiling-mounted and leaf switches are in-row. The violet jacket provides instant visual confirmation that you're working with OM4 during MAC work, reducing the risk of accidentally patching OM3 (aqua) or OM5 (lime green) into a circuit expecting OM4's bandwidth.

Panduit Opti-Core patch cords ship factory-terminated and individually tested, with insertion loss values laser-etched on the strain relief boot or included on a test report card. This removes the variability introduced by field termination—connector geometry, polish quality, and cleanliness all directly impact insertion loss, and even experienced techs see 0.1 to 0.3 dB spread across multiple terminations of the same connector type. By contrast, factory LC terminations on this jumper consistently land below 0.15 dB, often below 0.10 dB, giving you measurable headroom against the IEEE 802.3 channel insertion loss limits (1.5 dB for 40GBASE-SR4, 1.9 dB for 100GBASE-SR10). That headroom accommodates an extra mated pair in the channel, compensates for higher-than-expected backbone cable attenuation as the installation ages, or simply ensures that 40G/100G links train without forward error correction penalty. The G-code/standard LC hybrid configuration (one end keyed, one end standard) is purpose-built for secure-to-unsecure demarcation points: terminate the G-code end in your secure zone where only authorized personnel have physical access to matching G-code adapters, and terminate the standard LC end in a general-access cross-connect or equipment room. This creates a one-way physical gate—cables can't be accidentally or maliciously re-routed from the secure side without the correct keyed infrastructure.
