Panduit FY9WP77B005F076 48-Fiber Singlemode Plenum Trunk Cable Assembly
The Panduit FY9WP77B005F076 is a factory-terminated, 48-fiber singlemode indoor trunk cable assembly from the Panduit QuickNet HD Flex line — built for data centers, telecommunications rooms, entrance facilities, and equipment distribution areas where installation speed and optical performance cannot be compromised. At 76 feet (23.2 meters), this red-jacketed OFNP-rated assembly ships ready to pull and plug, eliminating field termination labor and the variability that comes with it.
Overview
Pre-terminated fiber optic trunk cable assemblies like the FY9WP77B005F076 exist because field termination is slow, skill-dependent, and introduces insertion-loss variation that can degrade link budgets across a high-density run. Panduit's QuickNet HD Flex platform addresses this directly: the assembly leaves the factory with connectors installed, polished, and tested — you get a verified optical performance baseline before the cable ever touches your ladder rack. The 48-fiber count makes this a strong fit for high-density backbone runs between main distribution areas (MDAs) and horizontal distribution areas (HDAs), or for connecting high-density patch panels and fiber enclosures in core switching rows.
Key Features
- 48 Singlemode Fibers: Singlemode glass supports long-distance, high-bandwidth transmission at 1310nm and 1550nm wavelengths — this trunk can carry 100G or 400G wave-division multiplexed signals across campus or inter-building links where multimode would run out of reach. For intra-data-center backbone runs, 48 fibers provides enough capacity to support dense port aggregation without multiple parallel trunks.
- ST Connectors: The ST bayonet-style connector is a field-proven interface common in telecommunications rooms and enterprise distribution frames. ST terminations lock securely and resist vibration, which matters in active equipment rooms where cable trays flex and airflow equipment creates ambient vibration. Verify your patch panels and fiber enclosures use ST ports before ordering — fiber patch panels with SC or LC ports will require adapter sleeves.
- Plenum (OFNP) Flammability Rating: OFNP-rated jacketing is required by the NEC when routing through air-handling spaces — plenum ceilings, raised floors with active HVAC return paths, and above-ceiling cable trays in commercial buildings. Substituting riser-rated (OFNR) cable in a plenum space is a code violation and a fire suppression risk. The FY9WP77B005F076's OFNP rating means it's compliant by default for the most restrictive routing environments you'll encounter in commercial construction.
- 76-Foot Factory Length (23.2m): The 76ft pre-cut length suits common inter-rack and cross-connect runs in mid-to-large data hall configurations. Factory termination means zero field splicing and no cleave-and-crimp variables — every fiber arrives at insertion loss specs set at the factory, not dependent on technician technique or field conditions.
- Red Cable Jacket: Red jacketing follows TIA-606-C administration standard color conventions for singlemode fiber in many enterprise environments, supporting consistent visual identification when color-coded structured cabling administration is in place. In mixed-fiber environments, the red jacket makes singlemode trunks visually distinct from OM3 (aqua) and OM4 (magenta) multimode runs at a glance.
- QuickNet HD Flex Sub-Brand: The HD Flex platform is engineered for high-density deployment with small-diameter construction — reduced cable weight and bend radius compared to conventional loose-tube trunk cables, which simplifies routing through congested cable trays and tight bend points in structured pathway systems. This translates directly to faster pulls and fewer installation errors in high-fill environments.
- Indoor Application Rated: This assembly is specified for indoor environments — data centers, telecom rooms, entrance facilities, and equipment distribution areas. It is not rated for direct burial, aerial, or outdoor conduit runs. Proper indoor routing through conduit or cable trays is assumed.
Integration & Compatibility
The FY9WP77B005F076 integrates with any ST-compatible fiber patch panel, fiber distribution frame, or active equipment port. ST is an older interface standard — verify your target hardware's front-panel interface before procurement. Many current high-density panels use LC or MPO/MTP ports; if your panels are LC or MPO, you will need ST-to-LC or ST-to-MPO adapter modules, or a different trunk assembly from the Panduit catalog. The OFNP jacket is backward-compatible with all plenum and riser routing environments. The 48-fiber singlemode design pairs directly with singlemode-capable transceivers (SFP+, QSFP28, QSFP-DD) operating at 1310nm or 1550nm in aggregation and core switching equipment.
Frequently Asked Questions
Q: Is the FY9WP77B005F076 suitable for plenum ceiling installations?
A: Yes. The FY9WP77B005F076 carries a Plenum (OFNP) flammability rating, which meets NEC requirements for installation in air-handling spaces including plenum ceilings and raised floors with active HVAC return paths.
Q: What connector type does the FY9WP77B005F076 use?
A: This assembly uses ST (Straight Tip) bayonet connectors. Before ordering, confirm your patch panels, fiber enclosures, or active equipment ports are ST-compatible. If your infrastructure uses LC or MPO/MTP ports, you will need adapter sleeves or a different trunk assembly.
Q: How many fibers does this trunk cable contain?
A: The FY9WP77B005F076 contains 48 singlemode fibers. This fiber count supports high-density backbone applications in data centers and telecommunications rooms.
Q: What is the exact length of the FY9WP77B005F076?
A: The assembly is 76 feet (23.2 meters) in length. It ships factory-terminated at this fixed length — field trimming would compromise the factory-finished connectors.
Q: Can the FY9WP77B005F076 be used for outdoor or direct burial runs?
A: No. This is an indoor-rated assembly. It is not rated for outdoor, direct burial, or aerial applications. For outdoor runs, a separate outdoor-rated trunk cable with appropriate jacketing is required.
Q: Is this a singlemode or multimode cable?
A: Singlemode. The FY9WP77B005F076 supports long-distance, high-bandwidth transmission at 1310nm and 1550nm wavelengths and must be paired with singlemode-compatible transceivers and equipment.
When I look at the FY9WP77B005F076, the spec that matters most in a data center backbone context is the OFNP plenum rating combined with the 48-fiber count — that combination tells me this trunk is built for the most restrictive commercial routing environments at meaningful density. A 48-fiber singlemode run at 76 feet covers the typical MDA-to-HDA span in a mid-to-large data hall without splicing or field termination, which is exactly where factory-terminated assemblies pay for themselves.
Technical Highlights:
- 48 Singlemode Fibers at 76ft (23.2m): Enough fiber count to support full aggregation-tier density in a single pull — eliminates parallel trunks and the cable management complexity that comes with them.
- OFNP Plenum Jacket: Compliant with NEC air-handling space requirements by default — no conditional routing, no code variance, no inspector conversation. This is the jacket you want when routing through above-ceiling return plenums in commercial construction.
- ST Connector Interface: Bayonet-lock ST connectors provide vibration-resistant termination suited to active equipment rooms. Factory polishing removes field variability from the insertion loss equation.
Deployment Considerations:
- ST is an older connector standard — audit your patch panels and fiber distribution frames before procurement. High-density LC and MPO/MTP panels are now common; mismatched connector types require adapter sleeves that add insertion loss and cost.
- This assembly ships at a fixed 76-foot factory length. There is no field-trim option without destroying the factory connector — measure your run carefully before ordering, including slack loops and any tray routing overhead.
The FY9WP77B005F076 is the right call for enterprise data center backbone builds and telecommunications room interconnects where the routing path crosses plenum air-handling spaces and you need 48-fiber singlemode capacity between distribution frames without field termination labor.
