Panduit FS2EPKELENEM015 Opti-Core™ 2-Fiber OM4+ Duplex LC Patch Cord

The Panduit FS2EPKELENEM015 delivers 40/100 Gbps OM4+ performance in a 15-meter plenum-rated patch cord engineered for high-density data center and enterprise backbone installations. Featuring Signature Core™ fiber with ultra-low insertion loss and E-coded physical-layer security on one end, this duplex LC jumper prevents unauthorized patching while maintaining backward compatibility with standard LC infrastructure. OFNP jacket qualifies for air-handling spaces without conduit.

Key Features

• OM4+ Signature Core™ fiber supports 40GBASE-SR4 to 150m and 100GBASE-SR4 to 100m per IEEE 802.3ba
• E-coded duplex LC connector on one end pairs exclusively with matching E-keyed adapters for physical access control
• Standard non-coded duplex LC on opposite end maintains compatibility with existing patch panels and switches
• Ultra-low insertion loss optimized for multi-mode 850nm laser transceivers in QSFP+ and QSFP28 modules
• OFNP plenum rating meets NFPA 262 for installation in return-air plenums and vertical risers
• 1.6mm zipcord jacket provides bend-radius protection and simplified cable management in high-density racks

OM4+ fiber delivers 4700 MHz·km effective modal bandwidth at 850nm—exceeding OM4's 3500 MHz·km baseline and enabling longer 40/100G reach without expensive single-mode upgrades. Signature Core manufacturing controls core geometry to ±0.5µm concentricity, reducing insertion loss variability across connector matings. Field measurements consistently show <0.15 dB insertion loss per connection, leaving margin for link budgets in 24-port breakout scenarios where seven duplex LC connections aggregate into QSFP28 modules.

The E-coded connector system adds a mechanical key profile to the LC boot, preventing insertion into standard adapters while allowing standard LC plugs to mate with E-coded adapters. Deploy E-coded jumpers on the equipment side of secure cross-connects—storage arrays, core switches, or surveillance NVR uplinks—while using standard patch cords on the horizontal side. The 15-meter length suits backbone runs between adjacent rows or vertical distribution from raised-floor networks to overhead cable trays. Plenum rating eliminates the need for conduit in 90% of commercial installations, reducing material cost and simplifying MACs.

Orange jacket color follows TIA-598-D identification for 50/125µm OM4 fiber, though the OM4+ performance enhancement is specified through Panduit's extended testing. RoHS compliance allows deployment in EU and California projects without hazardous-substance waivers. Duplex LC footprint matches industry-standard panel density—24 duplex ports in 1U—and mates with Panduit FAP adapter panels, Corning Edge modules, and Commscope LGX cassettes without dimensional interference.
