Panduit FHP9N-LA1X04 HD Flex 1x4 PON Splitter Cassette LC/APC OS2
Overview
The Panduit FHP9N-LA1X04 is a half-width passive optical network (PON) splitter cassette from the Panduit HD Flex™ fiber optic line designed to split a single OS2 single-mode input into four outputs — all via LC/APC duplex connectors — while fitting directly into FLEX**04 enclosures and panels. If you're building or expanding a PON infrastructure and need to maximize usable rack space without sacrificing port density, this cassette slots into the same chassis alongside other HD Flex modules: up to 18 cassettes fit in a single rack unit. The FHP9N-LA1X04 (often searched as FHP9N LA1X04) is a purpose-built passive component that requires no power and introduces no active failure points into your fiber distribution layer.
Key Features
- 1x4 PON Split Ratio: A single OS2 input is passively distributed to four LC/APC outputs. In a fiber-to-the-premises or enterprise campus distribution design, one feeder fiber from the OLT feeds four subscriber or zone circuits — no active electronics, no maintenance interval.
- LC/APC on Both Ports: Both input and output connectors are LC duplex with APC (angled physical contact) polish. APC terminations reduce back-reflection to levels well below the UPC threshold, which matters on long OS2 runs where return loss degrades signal quality. Using APC on both ends ensures connector compatibility and predictable loss budgets throughout the link.
- OS2 Single-Mode Fiber, 9µm Core: The 9-micron fiber diameter is standard single-mode OS2, compatible with 1310nm and 1550nm wavelength systems. This is not a multimode cassette — verify your transceiver wavelength and fiber type before mixing into a multimode plant.
- Half-Width Form Factor, 18 Cassettes per U: At 55.4mm wide and 11.7mm tall, this cassette occupies half the width of a standard module slot. Fitting 18 of these in 1U means a single rack unit can terminate 72 OS2 fibers (18 cassettes × 4 fibers each) — a real density advantage in colocation or enterprise MDA/IDA environments where every U is accountable.
- Integrated Port Shutters: Each LC/APC port ships with integral dust shutters. In active data centers and telecom rooms where cassettes may sit partially populated for weeks during phased buildouts, shutters prevent contamination without requiring separate dust caps to be ordered, tracked, or lost.
- Direct Chassis Integration (FLEX**04 Compatible): The FHP9N-LA1X04 installs directly into Panduit FLEX**04 enclosures and panels without adapters. If you're already deploying fiber optic cassettes in an HD Flex chassis, this splitter cassette slides in alongside standard duplex and MPO modules in the same frame — no dedicated splitter shelf required.
- Zirconia Ceramic Ferrules: The ferrule material is zirconia ceramic, the standard for precision fiber connectors. Zirconia's dimensional stability and hardness maintain tight tolerances over repeated connect/disconnect cycles, which matters in any distribution point that gets re-patched during moves, adds, and changes.
- RoHS Compliant, Multi-Standard: The cassette meets or exceeds ISO/IEC 11801, ANSI/TIA-568-C.3, TIA-604-5 (FOCIS-5), and TIA-604-10 (FOCIS-10), plus RoHS. For enterprise procurement and government projects with materials compliance requirements, the RoHS declaration and TIA/ISO alignment are already on the spec sheet — no additional testing required.
Integration & Compatibility
The FHP9N-LA1X04 is designed exclusively for installation in Panduit FLEX**04 fiber optic panels and enclosures. It is not a universal cassette — verify your existing chassis model before ordering. The half-width format means you can mix splitter cassettes with standard LC duplex or MPO cassettes in the same 1U panel, giving you the flexibility to allocate only as many split ports as your PON architecture requires without dedicating an entire shelf to splitting.
On the fiber plant side, OS2 single-mode and LC/APC are the required conditions. If your existing infrastructure is terminated in LC/UPC or you're running OM3/OM4 multimode, this cassette is not the right fit. For fiber optic cabling infrastructure planning guidance, verify your end-to-end loss budget including the split loss (a 1x4 passive splitter introduces approximately 6–7 dB of split loss in addition to connector insertion loss) before finalizing your OLT transmit power margin.
Frequently Asked Questions
Q: What enclosures is the FHP9N-LA1X04 compatible with?
A: The FHP9N-LA1X04 is designed to install directly into Panduit FLEX**04 enclosures and panels. It is a half-width cassette format, so it is not compatible with full-width or non-FLEX**04 chassis. Verify your panel model before ordering.
Q: Are the connectors LC/UPC or LC/APC on this cassette?
A: Both input and output connectors are LC duplex APC (angled physical contact). APC connectors reduce back-reflection significantly compared to UPC — they are not interchangeable without a mating sleeve adapter and will exhibit higher reflectance if mated directly to LC/UPC connectors.
Q: What fiber type does the FHP9N-LA1X04 support?
A: This cassette uses OS2 single-mode fiber with a 9µm core diameter. It is not rated for multimode fiber (OM1/OM2/OM3/OM4). Confirm your fiber plant is OS2 single-mode before deployment.
Q: How many of these cassettes fit in a single rack unit?
A: Up to 18 FHP9N-LA1X04 cassettes fit per U within a compatible FLEX**04 enclosure. At 4 fibers per cassette, that yields up to 72 OS2 fiber connections per rack unit from splitter cassettes alone.
Q: Does the FHP9N-LA1X04 require any active power or electronics?
A: No. This is a fully passive optical splitter. It requires no power connection and contains no active components, which eliminates a failure point in your fiber distribution layer.
Q: What standards does the FHP9N-LA1X04 meet?
A: The cassette meets or exceeds ISO/IEC 11801, ANSI/TIA-568-C.3, TIA-604-5 (FOCIS-5), and TIA-604-10 (FOCIS-10), and is RoHS compliant.
The FHP9N-LA1X04 is one of those components that looks simple on paper but has real deployment implications if you get the chassis or connector type wrong. The half-width form factor and 18-cassettes-per-U density make it genuinely useful in high-density PON distribution points — but it only installs in Panduit FLEX**04 enclosures, and both port sides are LC/APC, which is non-negotiable.
Technical Highlights:
- 1x4 Passive Split: No active components means no power budget to manage at the cassette level — just account for the ~6–7 dB passive split loss in your OLT link budget before committing to this split ratio at distance.
- Half-Width at 55.4mm × 11.7mm: 18 cassettes in 1U translates to 72 terminated OS2 fibers per rack unit from splitting alone. For phased PON rollouts, you can populate only the cassettes you need immediately and fill the rest later without touching the chassis.
- Zirconia Ceramic Ferrules with Integral Shutters: Zirconia ferrules hold tolerances through repeated mating cycles — relevant in any distribution point that gets re-patched regularly. The integral shutters are practical: no loose dust caps to manage during phased deployment.
Deployment Considerations:
- Confirm your chassis is a FLEX**04 variant before ordering — the FHP9N-LA1X04 will not slide into earlier or non-Panduit enclosures, and there's no adapter bracket for it.
- LC/APC and LC/UPC are not directly interchangeable — mating APC to UPC through a standard duplex coupler introduces measurable return loss penalty. If your existing patch cords are UPC, you'll need APC-to-APC throughout or appropriate hybrid adapters.
This cassette is the right call for enterprise campus or carrier-edge PON distribution where you're consolidating splitting and patching into a single FLEX**04 chassis, want passive reliability, and need the density to justify rack space costs at the MDA or IDA layer.
