Panduit FS2EPKCLCNCM003 Opti-Core OM4+ Fiber Patch Cord

The Panduit FS2EPKCLCNCM003 is a 3-meter OM4+ fiber patch cord built for 40GBASE-SR4 and 100GBASE-SR4 datacenter links where physical layer security and ultra-low loss matter. One end terminates with a C-code keyed duplex LC connector; the other end is non-keyed duplex LC. This asymmetric keying prevents unauthorized re-patching in secure facilities—only C-code adapters accept the keyed end, while the non-keyed end connects to standard LC infrastructure. OFNP plenum rating qualifies it for air-handling spaces without conduit.

Key Features

OM4+ Signature Core fiber supports 40/100G up to 150m and 10G to 550m over 850nm VCSEL transceivers

C-code keyed LC on one end, non-keyed LC on the other—enforce patch panel zoning without adapter swaps

Ultra-low insertion loss (<0.15 dB typical) preserves link budget on congested spine-leaf fabrics

OFNP plenum jacket meets NEC 770.179 for installation above drop ceilings and in return-air plenums

1.6 mm zipcord jacket—flexible routing in high-density patch panels and zero-U cable managers

Green jacket simplifies field identification in multi-tier OM3/OM4/OM4+ deployments

Panduit's Signature Core geometry delivers consistent 50 µm core diameter and numerical aperture across the entire 3-meter length, reducing modal dispersion and extending reach on 40G/100G links. The C-code keying system physically blocks mis-patching: keyed connectors mate only with keyed adapters, while the non-keyed end accepts standard LC connections. Use this cord to secure uplinks from access-layer switches to distribution aggregation points—patch the keyed end into a locked C-code panel, leave the non-keyed end at the switch. An intruder can't re-patch the keyed end to exfiltrate traffic without the matching adapter.

OM4+ extends OM4's 40/100G reach from 100m to 150m at 850nm, buying runway for spine-leaf expansion without re-cabling. Each fiber supports 10GBASE-SR to 550 meters, well beyond the 300m OM3 limit—critical when consolidating datacenter halls or linking adjacent buildings. The 1.6 mm zipcord jacket flexes through tight bend radii (10× jacket diameter minimum) without kinking, and the duplex LC footprint matches the port density of 1U 48-port Ethernet switches and 1U 24-port fiber panels.

OFNP plenum rating certifies low smoke and flame spread per UL 910, required for horizontal and vertical pathways in occupied spaces. RoHS compliance confirms lead-free, low-halogen construction for European and California procurement. Whether you're wiring a 100G QSFP28 spine, securing a financial trading floor's patch infrastructure, or future-proofing an enterprise core with OM4+ for 400G breakout, this Opti-Core patch cord delivers the loss performance, bend tolerance, and keying security that installers need.
