Panduit FS2EPKBLBNBM020 Opti-Core OM4+ 20m Duplex LC Fiber Patch Cord

The Panduit FS2EPKBLBNBM020 is a 20-meter OM4+ duplex fiber patch cord engineered for high-density datacenter and enterprise backbone deployments requiring physical-layer security. Built on Signature Core glass with ultra-low insertion loss, this plenum-rated (OFNP) jumper features Panduit's keyed B-code connector system on one end and standard LC on the other—enabling controlled migration between secured and legacy infrastructure. The 1.6mm zipcord jacket design reduces pathway congestion in cable managers and breakout panels, while OM4+ bandwidth headroom supports 40/100G Ethernet and future protocol upgrades without re-cabling. Red jacket for instant visual identification in mixed-mode fiber plants.

Key Features

• OM4+ Signature Core fiber delivers ultra-low insertion loss (typically <0.15 dB at 850nm) for maximum link budget
• Keyed B-code LC connector on one end and standard LC on the other for secure-to-shared zone interconnection
• OFNP plenum rating meets NEC 770.179(A) requirements for unrestricted air-handling space installation
• 20-meter length bridges datacenter row-to-row and building floor-to-floor distances without splicing
• 1.6mm zipcord jacket minimizes cable manager fill by 40% versus round cordage in high-density panels
• 4700 MHz·km bandwidth at 850nm future-proofs infrastructure for 100G and 400G migrations
• Red jacket aligns with TIA-598-D multimode identification standards for error-free field deployment
• RoHS compliant construction for global regulatory compliance

Panduit's Opti-Core Signature Core fiber utilizes precision-optimized core geometry to deliver industry-leading insertion loss performance—typically under 0.15 dB across the 850nm multimode window. This margin matters in 40GBASE-SR4 and 100GBASE-SR4 links where every tenth of a dB extends reach or enables additional splice points without exceeding the IEEE 802.3ba loss budget. The factory-terminated LC connectors use ceramic ferrules with sub-micron concentricity tolerance, eliminating the field-polish variability that plagues on-site terminations. OM4+ bandwidth specification (4700 MHz·km at 850nm) future-proofs the link for next-generation protocols when switch hardware catches up, avoiding the cost and downtime of a second fiber pull.

The keyed/non-keyed B-code configuration addresses a common datacenter security requirement: connecting a high-security zone (financial trading floor, healthcare PACS core, government enclave) to a shared infrastructure zone (ISP demarcation, campus backbone, co-location cross-connect) without exposing keyed patch panels to unauthorized access. Install keyed B-code panels inside the secure perimeter and standard LC panels in the shared space. This asymmetric cord bridges both without requiring duplicate keying hardware on the untrusted side. The 20-meter length handles typical intra-building scenarios—riser closet to server room, core switch to edge aggregation, SAN head-end to compute rack—without the insertion-loss penalty of fusion splicing shorter jumpers. The 1.6mm zipcord jacket (versus 2.0mm or 3.0mm round cordage) reduces cable manager fill by 40%, critical in high-density 1U/2U patch panels where 96-fiber breakouts compete for vertical pathway space.

OFNP plenum rating allows unrestricted installation in air-return plenums, suspended ceiling spaces, and HVAC pathways without costly conduit or fire-stopping—streamlining authority-having-jurisdiction inspections and reducing per-drop labor. The red jacket color aligns with TIA-598-D multimode identification standards, preventing accidental cross-connection with OS2 singlemode yellow trunks during adds, moves, and changes. Factory testing and serialized documentation ensure every cord ships with measured insertion loss and return loss data, satisfying structured cabling warranty requirements and providing a known-good baseline for future troubleshooting. For integrators deploying Panduit Unified Physical Infrastructure systems, the B-code keying integrates directly with FZ-series keyed cassettes and FAP high-density panels, creating an end-to-end physical security layer that complements logical access controls.
