Panduit FDCSA-24-10URH FlexCore 24-Fiber OM4+ Cassette

The Panduit FDCSA-24-10URH is a front-access FlexCore fiber cassette that breaks out two 12-fiber MPO-12 male trunk connectors to 24 LC duplex ports, all terminated with OM4+ Signature Core multimode fiber. Designed for datacenter and enterprise network installers migrating to 40GBASE-SR4 and 100GBASE-SR4 Ethernet, this cassette delivers universal polarity flexibility and ultra-low insertion loss in a 1U-height module that integrates directly into Panduit's FlexCore ODF and OSF enclosure systems. Right-hand orientation supports structured left/right cassette pairing in high-density rack deployments.

Key Features

• OM4+ Signature Core Fiber: Extended-reach multimode rated for 550m at 10G, 150m at 40G, and 100m at 100G—outperforming standard OM4 bend-loss specs for tighter-radius datacenter cable routing
• Universal Polarity Architecture: Field-reconfigurable for both Type A (straight-through) and Type B (key-up/key-down) MPO trunk connectivity without re-termination or cassette swap
• Ultra Insertion Loss Performance: Factory-tested to exceed TIA-604-5 (FOCIS-5) and TIA-604-10 (FOCIS-10) standards, preserving critical link budget margin for 40G/100G SR4 optics with 1.5dB channel loss allocation
• 24-Fiber LC Duplex Breakout: Front-panel LC ports provide tool-free patch access while dual MPO-12 male rear connectors mate to standard 12-fiber backbone trunks—eliminates need for field splicing or re-pinning during moves/adds/changes
• FlexCore ODF/OSF Native Compatibility: Drop-in module for Panduit FlexCore enclosures with integrated labeling, color-coding, and bend-radius management—supports mixed cassette/panel/splice configurations in same enclosure
• Right-Hand Orientation: MPO connector position optimized for right-side cassette placement in paired left/right ODF layouts, ensuring minimum bend radius compliance when routing backend trunks through vertical cable managers
• Polycarbonate Housing with Integrated Strain Relief: Impact-resistant module withstands repeated LC connector insertions (>500 mating cycles) while maintaining fiber bend radius >30mm at all exit points—prevents microbend attenuation in active rack environments
• 10-Pack Carton Quantity: Contractor-friendly packaging for multi-rack datacenter builds—typically 4-6 cassettes per 1U FlexCore ODF enclosure, each enclosure supporting up to 144 LC duplex connections

Panduit's OM4+ Signature Core fiber in the FDCSA-24-10URH delivers measurably tighter performance than baseline OM4 specifications, particularly critical for 40GBASE-SR4 and 100GBASE-SR4 deployments that consume four or ten parallel fibers per link. Standard OM4 is rated for 400m at 40G and 150m at 100G; OM4+ Signature Core extends those distances to 550m and 125m respectively under IEEE 802.3ba worst-case modal bandwidth conditions. This headroom matters in enterprise campus backbone runs where a single cassette-to-cassette link may traverse multiple floor-to-floor riser segments, patch panels, and horizontal cross-connects. The ultra insertion loss spec—factory-tested on every LC and MPO connector—ensures that even after accounting for mated-pair insertion loss (0.35dB typical per connection), mode-field mismatch, and minor dirt contamination in the field, total channel loss stays well below the 1.9dB budget ceiling for 100G SR4 optics running at 25Gbps per lane. Installers working with Cisco Nexus 9000, Arista 7500R, or Juniper QFX10000 switches will find this margin essential when qualifying links beyond the transceiver vendor's conservative 70m OM4 distance rating.

The universal polarity design addresses the most common source of deployment errors in MPO-based cassette systems: trunk polarity mismatch. Traditional cassettes are pinned for either Method A (key-up to key-up, straight-through fiber mapping) or Method B (key-up to key-down, crossover mapping per TIA-568-C.0 Annex A). Ordering the wrong cassette type or mixing A and B cassettes in the same enclosure results in non-functional links that require truck rolls and cassette replacements. The FDCSA-24-10URH eliminates this risk with a sliding key mechanism on each MPO-12 connector—flip the key position, and the cassette automatically reconfigures its internal fiber mapping from A to B or B to A without opening the module or re-pinning connectors. This is particularly valuable in co-location or multi-tenant datacenter environments where the installer may not control the far-end trunk polarity, or in phased network migrations where legacy Method A infrastructure must interoperate with newer Method B deployments. The right-hand orientation further simplifies rack planning: in a typical two-post or four-post rack, left-hand cassettes route MPO trunks toward the left vertical cable manager, right-hand cassettes route toward the right manager, and the installer maintains symmetrical bend-radius compliance on both sides without crossing trunk cables over each other in the limited depth behind the ODF enclosure.

The FDCSA-24-10URH ships with full compliance documentation for ISO/IEC 11801, ANSI/TIA-568-C.3, and TIA-604-5/604-10 (FOCIS-5 and FOCIS-10 connector performance), making it pre-qualified for LEED, BREEAM, and ENERGY STAR datacenter builds that require third-party tested components. Every cassette includes a serialized test report with LC-to-MPO insertion loss values measured at 850nm and 1300nm wavelengths, ensuring that datacenter operators can produce end-to-end channel certification reports without re-testing individual cassettes in the field. The polycarbonate housing meets UL 94 V-0 flammability rating and RoHS 2002/95/EC material restrictions, required for plenum-adjacent installations and European Union deployments. For integrators supporting Fiber Channel SAN fabrics alongside Ethernet LAN infrastructure, the cassette's OM4+ fiber and ultra-loss connectors meet ANSI T11.2 FC-PI-6 specifications for 16GFC and 32GFC host-to-switch links, with sufficient margin to support future 64GFC and 128GFC standards using the same installed cassette base—a critical consideration for storage network architects planning 10-year infrastructure lifecycles in healthcare, financial services, and government verticals.
