Panduit FY9WP77B005F092 48-Fiber Singlemode Plenum Trunk Cable Assembly
Overview
The Panduit FY9WP77B005F092 is a factory-terminated 48-fiber singlemode small-diameter trunk cable assembly from the Panduit QuickNet HD Flex line — purpose-built for high-density structured cabling deployments where installation speed and plenum compliance both matter. At 92 feet (28 meters), this assembly connects main distribution areas to horizontal distribution areas in data centers, telecommunications rooms, and enterprise equipment rooms without field termination, cutting installation labor and eliminating connector performance variability.
The trunk ships with ST connectors and a red jacket for straightforward polarity and routing identification in multi-trunk environments. The small-diameter construction is a real advantage in congested pathways and overhead trays — it takes up less tray fill, bends more cleanly around corners, and reduces the cable weight load on ladder racks and J-hooks compared to standard-diameter trunk assemblies of equivalent fiber count.
Key Features
- 48-Fiber Singlemode Core: Forty-eight singlemode fibers in a single assembly let you install a full 48-strand backbone run in one pull — no staging multiple smaller trunks or managing a tangle of individual patch cords between frames. Singlemode glass supports longer reach and higher bandwidth headroom for 40G, 100G, and beyond as core links scale.
- Plenum (OFNP) Jacket Rating: OFNP is the required fire rating for cable routed through air-handling plenum spaces — suspended ceilings, raised-floor return paths, and above-ceiling raceways in commercial buildings. Installing non-plenum cable in these spaces fails NEC code inspection. This assembly meets that requirement out of the box, so it can go anywhere in the building envelope without a conduit workaround.
- 92-Foot (28-Meter) Pre-Terminated Length: Factory termination removes the single largest variable in field fiber work — connector endface quality. Manufacturer-terminated connectors are tested and documented before shipment; field terminations depend on technician skill, cleave quality, and epoxy cure. A 92-foot pull covers most MDA-to-HDA runs in mid-size data center rows without splicing or mid-span coupling.
- ST Connector Type: ST bayonet-style connectors provide a positive push-and-twist locking mechanism that resists accidental disconnection in high-vibration or high-traffic environments. Compatible with a wide installed base of legacy and current ST-compatible patch panels, switches, and media converters in enterprise and carrier environments.
- Small-Diameter Construction: Reduced outer diameter means tighter bend radii, lower tray fill, and easier routing through conduit and pathway fill points — a practical advantage in retrofit projects where available pathway space is already partially consumed.
- Red Cable Jacket: Color-coding by cable type is standard practice in structured cabling infrastructure (ANSI/TIA-606 identifies singlemode with yellow, but site-specific schemes vary). Red provides a visually distinct trunk identity in mixed-media environments, simplifying future moves, adds, and changes without tracing individual fibers.
- Pulling Eye End A: The integrated pulling eye on End A allows the assembly to be pulled through conduit or along cable trays without improvised field pulling grips that can stress the connectors or jacket — maintains factory endface integrity during the pull.
Integration & Compatibility
The FY9WP77B005F092 integrates with Panduit QuickNet HD Flex patch panels and cassette modules designed for small-diameter trunk infrastructure. ST connectors mate with any ST-compatible adapter panel, wall plate, or fiber switch port. Verify the receive-end port compatibility before ordering: ST is an older standard and some newer high-density panels ship with LC or MPO interfaces by default — confirm your patch panel adapter type matches.
For complete fiber optic cable assemblies and trunk infrastructure, review the full Panduit QuickNet family to match connector type, fiber count, and polarity scheme to your panel layout. This assembly is suitable for data centers, telecommunications rooms, entrance facilities, and equipment distribution areas requiring pre-terminated fiber for rapid deployment — the application profile directly matches campus backbone and inter-rack structured cabling in enterprise environments. Pair with a compatible patch panel at each end to complete the link.
Frequently Asked Questions
Q: What is the fiber count and fiber type in the FY9WP77B005F092?
A: The FY9WP77B005F092 contains 48 singlemode fibers. Singlemode glass supports longer transmission distances and higher bandwidth compared to multimode, making it appropriate for backbone runs and inter-building links.
Q: Is the FY9WP77B005F092 rated for installation in plenum air-handling spaces?
A: Yes. The assembly carries an OFNP (Optical Fiber Nonconductive Plenum) flammability rating, which meets NEC requirements for cable installed in plenum air-handling spaces such as suspended ceilings and raised-floor return paths. No conduit enclosure is required in plenum-rated pathways.
Q: What connector type is used on the FY9WP77B005F092?
A: Both ends use ST connectors — a bayonet-style push-and-twist interface common in enterprise and telecommunications environments. Verify your patch panels and equipment ports accept ST connectors before ordering.
Q: What is the exact length of the FY9WP77B005F092?
A: The assembly is 92 feet (28 meters) in overall length. This fixed, factory-measured length covers most MDA-to-HDA backbone runs in mid-size data center deployments without splicing.
Q: What does the pulling eye on End A allow during installation?
A: The integrated pulling eye on End A is designed for conduit or cable tray pulls. It allows a pull rope to attach directly to the assembly without field-rigged grips, which can stress the jacket or connectors and compromise endface quality on a factory-terminated assembly.
Q: What environments is the FY9WP77B005F092 designed for?
A: This assembly is intended for indoor use in data centers, telecommunications rooms, entrance facilities, and equipment distribution areas requiring pre-terminated fiber infrastructure for rapid deployment. It is not rated for outdoor or direct-burial applications.
When I spec a structured cabling project in a data center with active overhead plenum air handling, OFNP compliance is non-negotiable — and the FY9WP77B005F092 handles that requirement while delivering all 48 singlemode fibers in a single small-diameter pull at a fixed 92-foot (28-meter) length that lines up well with standard row spacing in mid-size raised-floor facilities.
Technical Highlights:
- OFNP Plenum Rating: Meets NEC requirements for air-handling spaces without conduit enclosure — saves real labor and materials in ceiling-routed backbone runs where conduit fill costs add up fast.
- 48-Fiber Count in Small Diameter: Packs 48 singlemode fibers into a reduced outer diameter, keeping tray fill low and bend management clean in congested pathways — a meaningful advantage over standard-diameter 48-fiber trunks when routing through partially occupied ladder racks or conduit stubs.
- Integrated Pulling Eye, End A: Lets you rig the pull properly without improvising a field grip that risks stressing the factory-terminated connector endfaces — keeps the factory test quality intact through the installation.
Deployment Considerations:
- ST connectors have a large installed base but are not the dominant interface on new high-density panels — confirm your patch panel adapter plates are ST-compatible before cutting a purchase order. Mixing ST trunks into an LC or MPO panel layout requires hybrid adapter plates and adds connector count to the link.
- At 92 feet fixed length, measure your actual MDA-to-HDA run including all vertical drops, horizontal offsets, and service loops before ordering — a fixed-length assembly that comes up short is a project delay, not a field fix.
This assembly is the right call for a greenfield data center or telecommunications room installation where the overhead pathway is plenum-rated, runs are in the 75–90 foot range, and the panel infrastructure is already committed to ST interfaces — it eliminates field termination labor and inspection risk in one factory-tested pull.
