Panduit FHSXN-12-10N HD Flex LC Splice FAP Cassette — 12-Fiber OM3

Overview

The Panduit FHSXN-12-10N is a 12-fiber OM3 LC splice cassette in the Panduit HD Flex™ fiber infrastructure family, designed for high-density structured cabling deployments where clean splice management and consistent port-to-port insertion loss matter. It ships as a pre-terminated fiber optic cassette housing six duplex LC adapters — the aqua adapter color is the industry-standard OM3 multimode identifier, so your techs can confirm fiber type at a glance without pulling documentation. The cassette body is black, 7.5 inches wide and 0.46 inches tall, sized to drop into HD Flex FAP-compatible panels and enclosures without tools or guesswork.

This is a splice-style cassette, meaning it accepts field-terminated or fusion-spliced LC pigtails rather than factory-terminated trunks. If your project uses pre-terminated MTP/MPO trunk cables, verify you have the correct cassette variant — this model (FHSXN-12-10N, often searched as FHSXN 12 10N) is built for the splice/pigtail workflow, not MTP fanout.

Key Features

• 12 Fibers via 6 Duplex LC Ports: Six duplex LC adapters in one 0.46-inch-tall cassette delivers a high port density for the footprint. In a multi-U enclosure, this keeps fiber counts high per rack unit — useful in IDF closets and data center ToR deployments where horizontal space is constrained.
• OM3 Multimode, Aqua Adapters: OM3 supports 10GbE to 300 meters and 40/100GbE at shorter reaches — the right fiber tier for campus backbone runs and inter-rack connections in enterprise LANs. The aqua adapter color is TIA-standardized for OM3, which prevents mislabeling errors during moves, adds, and changes.
• Zirconia Ceramic Ferrule Sleeves: Zirconia ceramic alignment sleeves provide tighter ferrule bore tolerances than phosphor-bronze alternatives, which translates to lower and more consistent insertion loss across the six port positions. On a splice cassette carrying aggregated backbone traffic, that consistency matters more than on any single link.
• HD Flex™ Platform Compatibility: Built into Panduit's HD Flex system, this cassette integrates with compatible HD Flex panels, enclosures, and cable management — a fiber optic panel and enclosure ecosystem designed so cassettes slide in and lock without individual port labeling work. If you are already specifying HD Flex hardware, this cassette is the native splice-format component.
• Meets or Exceeds ISO/IEC 11801, ANSI/TIA-568-C.3, FOCIS-5, FOCIS-10: Compliance with TIA-568-C.3 means the connector geometry and insertion loss are verified against the industry baseline for structured cabling — relevant for projects requiring documented standards conformance (BICSI, government, healthcare, and commercial TI specifications frequently mandate TIA-568 compliance). RoHS conformance covers EU environmental requirements and is increasingly required on North American education and government contracts.
• Single-Unit Packaging, 10-Unit Carton: Ships individually (package quantity 1), but the 10-unit carton quantity makes it practical to order in cassette-panel increments rather than one-offs, reducing per-unit freight overhead on larger structured cabling bills of materials.
• LC Ribbons Not Included: This is a hardware-only cassette. LC pigtails or ribbon fibers for the splice tray are ordered separately — plan your splice material procurement before installation to avoid job-site delays.

Integration & Compatibility

The FHSXN-12-10N is designed for use within the Panduit HD Flex™ platform. Confirm your panel or enclosure accepts HD Flex FAP cassettes before ordering — not all Panduit enclosures share the same cassette form factor across product generations. The duplex LC interface is standard, so patch cords and pigtails from any TIA-604-5 (FOCIS-5) compliant source will mate correctly. OM3 multimode fiber pairs with 850nm VCSEL transceivers standard in 10G SFP+ and 40/100G QSFP equipment; if your switches or servers use single-mode optics, this cassette is not the correct selection — you would need an OS2 single-mode variant instead. For projects requiring structured cabling documentation, the standards compliance package (ISO/IEC 11801, TIA-568-C.3, FOCIS-5, FOCIS-10) supports most enterprise and commercial system warranty programs. See the fiber optic installation planning guide for cassette-count and enclosure-slot planning guidance.

What's in the Box

Note: LC pigtails and splice ribbons are not included and must be ordered separately.

Frequently Asked Questions

Q: Does the FHSXN-12-10N support single-mode fiber?

A: No. The FHSXN-12-10N is specified for OM3 multimode fiber. The aqua duplex LC adapters are color-coded for OM3 per TIA standards. If your project requires single-mode (OS1/OS2), you need a different cassette variant with the appropriate adapter color and sleeve specification.

Q: Are LC pigtails or splice ribbons included with the FHSXN-12-10N?

A: No. The cassette ships as hardware only — six duplex LC adapters and the splice cassette body. LC pigtails and ribbon fibers for the splice positions must be ordered separately. Plan your splice material quantities before installation.

Q: What panel or enclosure does the FHSXN-12-10N fit into?

A: The FHSXN-12-10N is designed for the Panduit HD Flex™ FAP-compatible panel and enclosure system. Verify your specific enclosure model accepts HD Flex FAP splice cassettes before ordering — Panduit offers multiple cassette form factors across its product generations, and they are not universally interchangeable.

Q: What standards does the FHSXN-12-10N comply with?

A: The FHSXN-12-10N meets or exceeds ISO/IEC 11801, ANSI/TIA-568-C.3, TIA-604-5 (FOCIS-5), and TIA-604-10 (FOCIS-10). It is also RoHS compliant. These cover structured cabling performance, LC connector geometry, and environmental material requirements.

Q: What is the fiber count and port configuration of the FHSXN-12-10N?

A: The cassette provides 12 fibers across 6 duplex LC ports. Each duplex LC port carries 2 fibers (one transmit, one receive), so 6 ports × 2 fibers = 12 fibers total.

Q: What ferrule sleeve material does the FHSXN-12-10N use?

A: Zirconia ceramic. Zirconia ceramic alignment sleeves hold tighter bore tolerances than phosphor-bronze alternatives, supporting more consistent insertion loss values across all six port positions — a factor on aggregated backbone links where cumulative loss budgets are tight.

The FHSXN-12-10N is one of those cassettes that tends to get specified correctly when the structured cabling design is done right and substituted incorrectly when it isn't. The key detail: this is a splice-format FAP cassette, not an MTP/MPO fanout module. If your backbone design calls for fusion-spliced pigtails and you need OM3 LC at the panel face, this is the right hardware. If your design calls for pre-terminated MTP trunk cables, you're looking at the wrong product family entirely.

Technical Highlights:

• Zirconia Ceramic Sleeves: Tighter ferrule bore tolerances than phosphor-bronze — directly reduces insertion loss variability across all 6 duplex LC positions, which matters when you're stacking cassettes in a high-port-count backbone distribution frame.
• 0.46-Inch Profile: At 7.5 inches wide and 0.46 inches tall, this cassette is engineered for high-density panel loading. In a standard HD Flex enclosure, that thin profile is what lets you get meaningful fiber counts into a 1U or 2U footprint without sacrificing access for cleaning or re-termination.
• Multi-Standard Compliance (TIA-568-C.3, ISO/IEC 11801, FOCIS-5/10): Covers the standard conformance documentation most commercial integrators need for system warranty submissions on enterprise, healthcare, and government TI projects — all from a single cassette SKU.

Deployment Considerations:

• Confirm your HD Flex enclosure or panel explicitly accepts FAP splice cassettes — Panduit's cassette ecosystem includes both splice and MTP/MPO variants, and the slot interfaces differ. A mismatch here wastes a site visit.
• LC pigtails are not in the box. Budget and procure splice materials — LC pigtails, splice trays, and any associated strain relief — before the installation date. This cassette ships hardware-only.

Best fit: enterprise IDF/MDF consolidation points and data center inter-row backbone runs where the cabling plant uses OM3 multimode, the design calls for field-spliced terminations, and the enclosure is already specified as Panduit HD Flex — this cassette snaps into that design without compromise.
