Panduit FDSZO-24-10P 24-Fiber OM4 LC Duplex Front-Access Splice Cassette
Overview
The Panduit FDSZO-24-10P is a 24-fiber, multimode OM4 front-access splice cassette designed for FlexCore ODF (Optical Distribution Frame) and OSF enclosures. It terminates LC Duplex connectors on the front face against unterminated pigtails on the splice side, giving you a clean, organized, rear-spliced connection point in a single 0.46-inch-tall form factor. If you are building or expanding a structured cabling backbone in a data center or enterprise campus where OM4 multimode is your fiber plant standard, this cassette slots directly into the FlexCore chassis without adapters or reconfiguration.
The FDSZO-24-10P (often searched as FDSZO 24 10P) is rated to fiber-optic cabling standards including ISO/IEC 11801, ANSI/TIA-568-C.3, TIA-604-5 (FOCIS-5), and TIA-604-10 (FOCIS-10), which means the insertion loss and mechanical performance requirements are defined and testable — not just claimed. For network architects specifying a fiber optic panels and enclosures solution that has to pass Tier 1 or Tier 2 channel certification, having standards traceability baked into the component spec is the starting point, not an afterthought.
Key Features
- 24-Fiber OM4 Multimode: Supports 50-micron OM4 glass — the correct fiber type for 40GbE and 100GbE applications over the distances typical of campus and intra-data-center runs. If your plant is already OM4, this cassette maintains the integrity of that investment without a fiber type mismatch at the panel.
- LC Duplex Front Interface: LC is the dominant connector footprint in modern high-density cabling. Twelve LC duplex ports on a single cassette face let you terminate 24 fibers in a module that is only 11.53 inches wide and 0.46 inches tall — practical for frames where rack unit space is at a premium.
- Front-Access Design: Splice management happens from the front of the frame rather than requiring rear access. In a populated rack row where rear access is constrained or shared with power infrastructure, front-access splice cassettes let a single technician manage both ends of a fiber run without repositioning the rack or disconnecting adjacent equipment.
- Optimized Insertion Loss: The cassette is described as featuring optimized insertion loss (perte d'insertion optimisée) on the splice path. In a multi-hop backbone, insertion loss accumulates at every connection point — a cassette engineered for low loss buys margin in your optical link budget that you can apply to longer distances or additional passive components.
- Polycarbonate Construction: The housing material is polycarbonate — impact-resistant, dimensionally stable under the temperature swings in a data center environment, and lighter than metal alternatives. In a fully loaded ODF with dozens of cassettes, weight adds up; polycarbonate keeps the frame manageable without sacrificing mechanical integrity.
- RoHS Compliant: Meets RoHS 2002/95/CE, which is a procurement requirement for many enterprise and government end-users. If your project has a green or regulatory specification checklist, this cassette satisfies that line item.
- Multi-Standard Compliance: ISO/IEC 11801, ANSI/TIA-568-C.3, TIA-604-5, TIA-604-10, and compatibility with IEEE 802.3 and ANSI T11.2 (Fibre Channel) cover the major structured cabling and storage networking standards. A single cassette that spans both Ethernet and Fibre Channel standards reduces the SKU count in mixed-use backbone installations.
- FlexCore ODF/OSF Platform: Designed specifically for the Panduit FlexCore enclosure family. Platform-matched components mean the cassette slides and locks correctly, the port labeling aligns with the frame's documentation system, and you are not improvising a fit.
Integration & Compatibility
The FDSZO-24-10P is designed for installation in Panduit FlexCore ODF and OSF enclosures. The unterminated (pigtail) side is field-spliced to your incoming fiber, giving the installer flexibility to match the splice method — fusion or mechanical — to site conditions and budget. The LC Duplex front ports connect to active equipment, patch cords, or other passive distribution panels depending on your topology.
Standards compliance with TIA-604-10 (FOCIS-10) and TIA-604-5 (FOCIS-5) ensures the LC adapter and ferrule geometry meets published IEC and TIA specifications, which matters when mixing fiber optic patch cords from different manufacturers. The cassette also carries IEEE 802.3 and ANSI T11.2 compatibility notations, making it appropriate for both Ethernet backbone and Fibre Channel SAN environments in the same physical plant.
Package quantity is 1 cassette per unit; carton quantity is 10, which aligns with typical bulk procurement for multi-rack or multi-floor deployments. Plan your cassette count based on fiber count per run: each FDSZO-24-10P handles 24 fibers, so a 96-fiber trunk requires four cassettes.

Frequently Asked Questions
Q: What enclosures is the FDSZO-24-10P compatible with?
A: The FDSZO-24-10P is designed for Panduit FlexCore ODF (Optical Distribution Frame) and OSF enclosures. It is a platform-specific cassette and is not intended as a universal fit for other manufacturers' frames.
Q: What fiber type does the FDSZO-24-10P support?
A: It supports 50-micron OM4 multimode fiber. OM4 is appropriate for 40GbE and 100GbE applications at typical campus and data center distances. It is not rated for single-mode (OS1/OS2) applications.
Q: How many fibers does one cassette handle?
A: One FDSZO-24-10P accommodates 24 fibers, presented as 12 LC Duplex ports on the front face. A 96-fiber trunk would require four of these cassettes.
Q: What standards does the FDSZO-24-10P meet?
A: The cassette meets ISO/IEC 11801, ANSI/TIA-568-C.3, TIA-604-5 (FOCIS-5), TIA-604-10 (FOCIS-10), and RoHS 2002/95/CE. It is also noted as compatible with IEEE 802.3 and ANSI T11.2 (Fibre Channel).
Q: What is the physical size of the FDSZO-24-10P?
A: The cassette measures 11.53 inches (292.8 mm) wide and 0.46 inches (11.7 mm) tall. Its low profile allows high-density stacking within a FlexCore frame without consuming excessive rack height.
Q: Is the FDSZO-24-10P sold individually or in bulk?
A: The standard package quantity is 1 unit. Carton quantity is 10 units, which is typical for larger structured cabling deployments requiring multiple cassettes across a frame or floor.
The FDSZO-24-10P is a purpose-built splice cassette for the FlexCore platform — and the key detail that matters most in structured cabling deployments is that 24 fibers in a 0.46-inch-tall module is genuinely high density, not a marketing claim. When you are populating a multi-rack data center run with 96- or 144-fiber trunks, the math on rack height gets real fast, and this cassette's form factor keeps your ODF lean.
Technical Highlights:
- 50-Micron OM4 Fiber: OM4 supports 100GbE at 150 meters and 40GbE at 150 meters per IEEE 802.3 — the cassette's IEEE 802.3 compatibility notation directly supports these link budgets without requiring fiber plant upgrades.
- LC Duplex / 12-Port Front Face: Twelve LC duplex ports in an 11.53 x 0.46-inch footprint means you can stack multiple cassettes in a single 1U panel slot without burning rack space on adapter plates or patch panels with wasted port positions.
- Multi-Standard Compliance (ISO/IEC 11801, TIA-568-C.3, FOCIS-5/10): These are the certification checkboxes that matter when a project requires documented Tier 1 or Tier 2 channel testing. Having the cassette pre-qualified to these standards means you are not adding an unknown variable to your test results.
Deployment Considerations:
- The unterminated (pigtail) connector 2 side requires field splicing — budget for fusion splice labor and sleeve protection on every fiber before commissioning. This is not a plug-and-play cassette; it is a splice cassette, and the splice quality directly determines insertion loss performance.
- The FDSZO-24-10P is FlexCore-specific. Verify your enclosure model is within the ODF/OSF FlexCore line before ordering — this cassette will not mechanically fit or lock correctly in non-FlexCore Panduit frames or third-party enclosures.
This cassette is the right call for enterprise data center backbone builds or large campus MDA/IDA fiber distribution points where the cabling plant is already committed to OM4 and the ODF enclosures are FlexCore. It is not the pick for ad hoc or mixed-platform environments where cassette interchangeability across enclosure brands is required.
