Description

Panduit FDCZA-24-10URH FlexCore 24-Fiber OM4 LC/MPO Cassette

The Panduit FDCZA-24-10URH is a 24-fiber OM4 breakout cassette that converts two MPO-12 male backbone connectors into 24 LC duplex ports for equipment-side patching. Designed for FlexCore ODF and OSF enclosures, this right-hand orientation module delivers universal polarity support across Type A, B, and C trunk deployments—eliminating the need for field re-pinning or custom cable orders. The ultra-low insertion loss specification (<0.35dB typical) ensures link budget headroom for 40GBASE-SR4, 100GBASE-SR4, and extended-reach 10G applications where every tenth of a dB matters. If you're architecting high-density fiber distribution in enterprise datacenters, carrier hotels, or cloud infrastructure, this cassette is the bridge between your MPO backbone and active switching equipment.

Key Features

  • 24-fiber OM4 multimode cassette with LC Duplex breakout from 2× MPO-12 male connectors
  • Universal polarity design supports Type A, B, or C MPO trunk cables without re-termination
  • Ultra-low insertion loss (<0.35dB typical) optimized for 40G/100G SR optics and long 10G runs
  • Right-hand (RH) orientation for organized patching in paired left/right rack layouts
  • Fits Panduit FlexCore ODF and OSF enclosures for modular, scalable fiber infrastructure
  • 50µm OM4 fiber rated for 550m at 10GBASE-SR, 150m at 40/100GBASE-SR4
  • Polycarbonate housing with precision alignment for low back-reflection (<-50dB)
  • Compliant with ISO/IEC 11801, ANSI/TIA-568-C.3, TIA-604-5 (FOCIS-5), and TIA-604-10 (FOCIS-10)

The FDCZA-24-10URH uses laser-optimized 50µm OM4 fiber throughout, delivering the 4700 MHz·km effective modal bandwidth required for IEEE 40GBASE-SR4 and 100GBASE-SR4 applications at distances up to 150 meters. For 10GBASE-SR deployments, OM4 extends your reach to 550 meters—critical when distributing from centralized meet-me rooms to edge-of-row switches or cross-connecting between buildings on a campus backbone. The LC duplex interface uses Panduit's ceramic ferrule alignment system, holding core-to-core offset below 0.5µm for insertion loss under 0.35dB and return loss better than -50dB across all 24 ports. This isn't academic: in a 100GBASE-SR4 link running four parallel 25G lanes, each 0.1dB of excess loss cuts your margin by 2%, and stacking cheap cassettes with 0.75dB insertion loss leaves no headroom for patch cord degradation, dust contamination, or temperature drift over a 10-year service life.

The MPO-12 male pinout on the backbone side follows TIA-568-C.3 universal polarity conventions, meaning a single cassette design works with Type A (straight-through key-up/key-down), Type B (key-up/key-up with crossover), or Type C (key-up/key-down pairs) trunk cables. In practice, this eliminates the field chaos of \"do I need a Type A or Type B cassette for this run?\" that derails install schedules when the wrong module shows up on-site. You order one SKU, stock one SKU, and install into any polarity architecture your trunk vendor or cabling standard specifies. The right-hand orientation refers to the MPO connector placement on the cassette body: pairing RH modules on the top row with LH modules on the bottom creates clean horizontal cable routing with no crossover spaghetti inside the enclosure. If you've ever debugged a fiber link in a 144-fiber ODF where every strand looks identical, you know why organized physical layout isn't optional.

This cassette slots into Panduit FlexCore ODF (Optical Distribution Frame) and OSF (Optical Splice Frame) enclosures, which mount in standard 19-inch racks or wall brackets for centralized fiber cross-connects. A typical deployment: 12-fiber or 24-fiber OM4 MTP trunk cables run from a main distribution area (MDA) or entrance room to each row or zone, terminating on MPO-12 connectors. You plug those trunks into the back of FDCZA cassettes inside the ODF, and now the front of the frame presents 24 individual LC duplex ports per cassette—ready for standard LC patch cords to your switch, storage array, or server uplinks. The modular design means you can start with a 1U enclosure holding four cassettes (96 LC ports) and scale to a 4U frame with 16 cassettes (384 ports) without re-engineering the backbone or ripping out existing infrastructure. When your 10G switch refresh happens in three years and you're migrating to 40G or 100G, you don't replace the cassettes—just the patch cords and optics, because the OM4 fiber and MPO backbone are already rated for the job.

Datacenter and enterprise IT teams choose this cassette over pre-terminated harnesses or field-terminated panels when they need density, flexibility, and speed. A 24-fiber MPO trunk is 6mm in diameter; the equivalent 24 individual LC duplex cables (48 fibers total, 24 duplex pairs) would be a 38mm bundle. At scale, that's the difference between a manageable 2-inch cable tray and a 4-inch tray—or between fitting in your existing overhead pathway and having to re-bid the structural pathway contract. The ultra-low insertion loss variant (the \"PI ultra\" callout in Panduit's naming) is the go-to for carrier hotel meet-me rooms, cloud on-ramps, or any environment where you're aggregating dozens of hops and every connector in the chain contributes to your total link budget. If your fiber spans include 40GBASE-LR4 optics (rated for 10km but sensitive to loss), or if you're running CWDM/DWDM over the same infrastructure, the difference between a 0.35dB cassette and a 0.75dB cassette is the difference between a link that works and a link that throws CRC errors under load.

The FDCZA-24-10URH ships with full compliance documentation for ISO/IEC 11801 (international cabling standard), ANSI/TIA-568-C.3 (North American fiber), TIA-604-5 (LC connector physical spec), and TIA-604-10 (MPO-12 connector physical spec), which auditors and insurance underwriters expect to see in mission-critical installations. Panduit's FlexCore ecosystem—cassettes, enclosures, MPO trunks, and LC patch cords—is tested as a complete channel, not individual components cobbled from three vendors, so your end-to-end insertion loss, return loss, and polarity are predictable from design through commissioning. The black polycarbonate housing holds dimensional tolerances across -40°C to +85°C storage (typical datacenters run 18–27°C, so you have massive thermal margin), and the 11.7mm height fits two cassettes per 1U with room for cable bend-radius compliance. If you're building or expanding OM4 infrastructure and need a cassette that handles any polarity scheme, fits tight rack spaces, and won't eat your link budget on day one or year ten, the FDCZA-24-10URH is the module you spec.
