Panduit FZUYPXRNNONF050 FlexCore 24-Fiber OM4 LC Duplex Cassette Assembly

The Panduit FZUYPXRNNONF050 FlexCore cassette delivers pre-terminated 24-fiber OM4 connectivity in a front-access ODF format, engineered for datacenter spine-leaf architectures and enterprise backbone deployments where installation speed, port density, and long-term reliability outweigh the economics of field termination. Each cassette ships with factory-polished LC duplex connectors on the equipment side and unterminated pigtails for fusion splicing to your incoming trunk—combining the precision of controlled-environment termination with the flexibility to match any trunk configuration in the field. OM4 laser-optimized 50µm multimode fiber supports 40GBASE-SR4 to 150 meters and 100GBASE-SR4 to 100 meters per IEEE 802.3, making this cassette a drop-in solution for current 10G/40G networks with a clear migration path to 100G without re-cabling the horizontal.

Key Features

• 24-Fiber OM4 Multimode – Laser-optimized 50µm fiber rated for 40G/100G Ethernet, Fiber Channel, and InfiniBand at distances that cover typical datacenter row-to-EOR and building backbone runs
• Factory-Terminated LC Duplex Connectors – Pre-polished to <0.25 dB insertion loss in a controlled cleanroom environment, eliminating field polish variability and connector endface contamination risks
• Unterminated Trunk Side – 12-color 900µm tight-buffered pigtails for fusion splicing to your incoming trunk cable, providing full flexibility for trunk fiber counts, jacket types, and routing paths
• Front-Access ODF Architecture – Cassette slides into FlexCore ODF chassis for plug-and-play installation; all connector access, labeling, and cable management from the front panel without rear-rack access
• Plenum-Rated OFNP Jacket – UL 910 / NFPA 262 compliant for installation in air-handling spaces, overhead pathways, and above-ceiling horizontal runs without conduit
• 11.53" × 0.46" Form Factor – Fits standard 1U FlexCore ODF enclosures, stacking up to 288 LC duplex ports per rack unit for ultra-high-density patch fields
• Polycarbonate Housing – Impact-resistant cassette shell protects fusion splice trays and fiber routing during installation, maintenance, and accidental contact in congested racks
• Multi-Standard Compliance – Meets TIA-568-C.3, ISO/IEC 11801, TIA-604-5 (FOCIS-5) LC connector geometry, and TIA-604-10 (FOCIS-10) MPO geometry for interoperability across vendor ecosystems

The FZUYPXRNNONF050 cassette solves the classic datacenter install dilemma: field termination of 24-fiber trunks is labor-intensive, requires specialized polishing skills, and introduces insertion-loss variability that can push links beyond loss budgets on 40G/100G optics. Pre-terminated trunk assemblies eliminate field termination but lock you into fixed lengths and trunk counts, creating waste and limiting flexibility when your patch-panel-to-switch distances don't match off-the-shelf increments. Panduit's tethered cassette architecture splits the difference—factory-terminated LC connectors on the equipment side for consistent performance, unterminated pigtails on the trunk side for field fusion splicing. You get sub-0.25 dB connector performance, full control over trunk routing and length, and the ability to match any trunk fiber count by splicing only the fibers you need. The plenum-rated OFNP jacket on the cassette's pigtails means you can route directly to overhead pathways or ceiling-mounted splice enclosures without transitioning to a separate plenum trunk, simplifying BOM and reducing splice points. The cassette's polycarbonate housing encloses a protected splice tray where your fusion splices live, shielded from the mechanical stress and bend-radius violations common in dense ODF environments.

Front-access ODF systems like FlexCore are built for the realities of production datacenter operations: rear rack access is often blocked by power whips, cable trays, or back-to-back row layouts, and any maintenance task that requires moving equipment or disturbing adjacent racks costs operational velocity. The FZUYPXRNNONF050 cassette slides into a FlexCore 1U chassis from the front, latches without tools, and presents all 24 LC duplex ports on the front panel. Patch cord insertion, port identification, and cleaning happen from the hot aisle or cold aisle without reaching behind the rack. When you need to add a cassette or replace one, you slide it out, swap it, and slide the new one in—no cable dressing, no disturbing adjacent equipment, no coordination with facilities to move a rack. This architecture is particularly valuable in colocation environments where cage access, power-down windows, and rack-touch time all carry direct cost. The cassette's 11.53-inch width and 0.46-inch height allow 12 cassettes per 1U FlexCore enclosure, delivering 288 LC duplex ports per rack unit—density that matches or exceeds MTP-based solutions while maintaining the per-port accessibility and troubleshooting simplicity of discrete LC connectors. If you're migrating from copper to fiber or upgrading from OM3 to OM4, you can populate cassettes incrementally, one row at a time, without forklift-upgrading an entire rack or pre-buying capacity you won't use for two years.

OM4 fiber's 50µm core and laser-optimized refractive index profile are engineered specifically for 850nm VCSEL transceivers—the dominant optic type in 10GBASE-SR, 40GBASE-SR4, and 100GBASE-SR4 deployments. The FZUYPXRNNONF050's OM4 specification guarantees 4700 MHz·km modal bandwidth at 850nm, supporting 10G Ethernet to 550 meters, 40G Ethernet to 150 meters, and 100G Ethernet to 100 meters per TIA-568-C.3 and IEEE 802.3. These distances cover 95% of datacenter intra-building links: row-to-end-of-row aggregation, floor-to-floor backbone risers, and meet-me-room-to-equipment-room trunks all fit within OM4's reach without requiring the cost premium and handling complexity of singlemode fiber. If you're running 10G today with an eye toward 40G in the next refresh cycle and 100G in three years, OM4 gives you a single cabling infrastructure that supports all three generations without stranding prior investment. The cassette's LC duplex interface is the de facto standard for 10G/25G server NICs and switch ports; 40G/100G links use parallel optics (MPO) on the transceiver side but often break out to LC duplex at the patch panel via MPO-to-LC cassettes or harnesses, so deploying LC duplex cassettes now preserves compatibility across migration waves.

This cassette is RoHS 2002/95/EC compliant for lead-free, low-halogen installation in EU and global markets, and the plenum OFNP jacket meets UL 910 flame and smoke limits for unrestricted use in NFPA 90A air-handling spaces. TIA-568-C.3 and ISO/IEC 11801 compliance ensures interoperability with any standards-compliant fiber infrastructure, while TIA-604-5 and TIA-604-10 connector geometry specs guarantee physical compatibility with LC and MPO interfaces from any vendor. For hyperscale deployments, healthcare networks under HIPAA physical-security mandates, or financial trading floors where every microsecond of latency and every dB of loss matters, the FZUYPXRNNONF050 delivers factory-verified performance with the field flexibility to fit your exact trunk topology—no compromises, no rework, no variance.
