Panduit FS2EPKFLFNFM005 Opti-Core OM4+ Keyed Fiber Patch Cord
The Panduit FS2EPKFLFNFM005 delivers OM4+ Signature Core performance in a plenum-rated duplex patch cord engineered for high-density data centers and secure enterprise networks. This 5-meter cord features Panduit's keyed connector system—one end coded F, the other uncoded—providing physical layer security by allowing only matching components to mate. Built on 2-fiber OM4+ technology with ultra-low insertion loss, it supports 40/100 Gigabit Ethernet applications while maintaining the bend performance and reliability installers expect from Panduit's Opti-Core platform.
Key Features
- OM4+ Signature Core fiber supports 40/100GbE at extended distances with margin for future speed upgrades
- Keyed connector system (F-coded on one end, uncoded on the other) prevents unauthorized patching and cable mix-ups
- Plenum-rated (OFNP) zipcord jacket qualifies for air-handling spaces without additional conduit
- Ultra-low insertion loss specification ensures reliable signal integrity in multi-hop topologies
- Duplex LC format fits standard SFP+ and QSFP+ transceiver modules in switches and servers
- 1.6mm zipcord cable construction simplifies routing in congested pathways and patch panels
Panduit's OM4+ fiber extends the performance envelope of standard OM4 by tightening manufacturing tolerances on core geometry and modal bandwidth. The result: longer reach for 40GBASE-SR4 and 100GBASE-SR4 applications, reduced bit error rates, and headroom for 200G/400G migrations when paired with appropriate transceivers. The keyed connector system adds a layer of physical security often required in government, healthcare, and financial networks—color-coded keys ensure that only authorized patch cords connect to designated ports, reducing the risk of accidental cross-connects or malicious tampering. The F-key designation allows you to build segmented networks where critical infrastructure uses one key family and general access uses another.
The 5-meter length bridges typical cross-aisle distances in raised-floor data centers and server rooms, while the plenum-rated OFNP jacket meets NEC requirements for overhead cable trays and drop-ceiling installations. The slim 1.6mm zipcord profile reduces congestion at high-density patch panels, and the duplex LC footprint maximizes port density on spine switches and blade chassis. Each cord ships factory-terminated and tested, eliminating the variability of field terminations and ensuring insertion loss performance out of the box. Panduit backs the Opti-Core line with comprehensive documentation, including insertion loss test data and compatibility matrices for their structured cabling systems.
This patch cord meets RoHS directives and integrates seamlessly with Panduit's broader Opti-Core ecosystem, including cassettes, trunk cables, and enclosures. For deployments requiring matching keyed infrastructure, pair with Panduit's F-keyed adapter panels and cassettes to maintain end-to-end physical layer security across your structured cabling plant.
