Panduit FS2EPKBLNNBM020 Opti-Core™ OM4+ 2-Fiber Coded Duplex LC Patch Cord

The Panduit FS2EPKBLNNBM020 delivers OM4+ fiber performance with physical-layer security for mission-critical datacenter and enterprise backbone deployments. This 20-meter plenum-rated patch cord features Signature Core™ ultra-low insertion loss and Panduit's B-code red connector system on one end, paired with standard duplex LC on the other — enabling secure, color-coded patching schemes that prevent unauthorized cross-connections in multi-tenant or high-security environments. Built on 1.6mm zipcord cable with OFNP flammability rating, it supports 40GBASE-SR4 to 150m and 100GBASE-SR10 to 100m over OM4 infrastructure, with headroom for future 400G deployments when paired with appropriate transceivers.

Key Features

• OM4+ Signature Core™ fiber for ultra-low insertion loss and extended reach on 40G/100G links
• B-code red duplex LC connector on one end; standard duplex LC on opposite end for secure, color-keyed patching
• OFNP plenum rating (cámara impelente) for installation in air-handling spaces per NEC 770.113(A)
• 20-meter (65.62 ft) length suits intra-rack, rack-to-rack, or horizontal cabling in raised-floor datacenters
• 1.6mm zipcord jacket construction balances flexibility with durability in high-density fiber trays
• 2-fiber duplex design supports full-duplex bidirectional communication on a single cable assembly
• RoHS compliant; backed by Panduit's Signature Core warranty program

OM4+ fiber extends the IEEE 802.3ba OM4 specification with tighter modal bandwidth control, yielding lower insertion loss and higher link margin than standard OM4 or OM3 cable. In 40GBASE-SR4 deployments, OM4 supports 150m reach; OM3 drops to 100m. For 100GBASE-SR10, OM4 reaches 100m vs. OM3's 70m limit. The Signature Core manufacturing process pre-qualifies every meter of fiber for insertion loss below 0.15 dB per mated pair at 850 nm, ensuring you hit link budgets even after accounting for connector cleaning degradation or multiple mating cycles. This becomes critical in spine-leaf fabrics where a single 100G uplink may traverse three or four patch points between server NIC and spine switch — every 0.05 dB saved at the patch cord translates to extended transceiver interoperability or the ability to use lower-cost optics without link flap.

The B-code red keying system is part of Panduit's color-coded connector family, which uses physical tab geometry to enforce patching rules at Layer 0. In a multi-tenant colo or classified government facility, you assign each tenant or security domain a unique color code; field techs physically cannot insert a red-coded plug into a blue-coded adapter, eliminating cross-connect errors that would bypass VLANs or firewall policies. The FS2EPKBLNNBM020 ships with B-code red on one end and standard (non-keyed) LC on the other, making it ideal for secure patch panels where the panel side uses keyed adapters and the equipment side (switch/server) uses standard LC ports. This asymmetric design lets you retrofit existing switch infrastructure without replacing optics or pigtails, while still gaining physical-layer access control at the distribution frame.

The 20-meter length handles typical datacenter runs: 15 meters covers worst-case overhead ladder-to-rack drops in a 12-foot ceiling; the remaining 5 meters accounts for service loops and slack management in fiber trays. OFNP plenum rating means the cable can route through ceiling return-air plenums without conduit, simplifying installation in retrofit projects where fishing new conduit would require asbestos abatement or fire-stop re-certification. Duplex LC remains the dominant connector in enterprise 10G/25G/40G/100G deployments due to its 1.25mm ferrule and push-pull latch, which delivers SFP/SFP+/QSFP form-factor density without the cleaning challenges of MPO/MTP multi-fiber connectors. The 1.6mm zipcord jacket uses two 900-micron tight-buffered fibers in a figure-8 cross-section, offering better bend performance than breakout cable and simpler termination than distribution cable.

Zipcord splits cleanly with a razor for furcation kits, yet remains robust enough for patch-and-play installations where the cable will be dressed through vertical managers and secured with hook-and-loop every 12 inches per TIA-942 guidelines. Panduit's Signature Core warranty covers insertion loss and return loss for the life of the installation when used with Panduit adapters and cleaning procedures, giving you a single-source accountability path if a link fails acceptance testing during turn-up. The red jacket provides immediate visual identification in mixed-mode fiber plants where OM3 aqua and OM4 violet cables coexist, reducing the risk of plugging 100G optics into legacy OM3 infrastructure and wondering why your BER climbs during temperature swings.
