Panduit FY9WP77B005F084 48-Fiber Single-Mode Indoor Plenum Trunk Cable Assembly
The Panduit FY9WP77B005F084 is a pre-terminated 48-fiber single-mode indoor trunk cable assembly from the Panduit QuickNet HD Flex lineup, designed to eliminate field termination labor in structured cabling deployments. At 84 feet (25.6 m), this trunk connects high-density patch panels, fiber distribution units, and zone enclosures in data centers, telecommunications rooms, entrance facilities, and equipment distribution areas where pre-terminated infrastructure accelerates turn-up and eliminates splice trays. The red jacket makes zone identification and cable management straightforward in multi-trunk environments.
Overview
Pre-terminated trunk assemblies like the FY9WP77B005F084 exist to solve a real operational problem: field-terminated fiber introduces human error, slows deployment timelines, and adds hidden labor cost. A factory-terminated trunk ships tested and ready to pull — you connect, route, and move on. The QuickNet HD Flex platform targets high-density spaces where minimizing cable diameter and bend radius without sacrificing fiber count matters for rack density and airflow. The 48-fiber count hits the sweet spot for inter-row or main-distribution-area runs where a single trunk replaces multiple smaller bundles.
Key Features
- 48-Fiber Single-Mode Count: 48 single-mode fibers in a single assembly covers 24 duplex LC or ST connections per end — enough to fully populate a 1U 24-port fiber patch panel in a single trunk run. That's one cable pull instead of 24 individual jumpers, which translates directly to fewer hours of labor and a cleaner cable plant.
- 84-Foot (25.6 m) Pre-Terminated Length: Factory-terminated at both ends and shipped pull-ready with a stranded intermediate pulling eye on the A-end, sized for data center inter-row spans and longer telecom room cross-connect runs. Measure your longest run before ordering — field-shortening a factory trunk is not a field option.
- ST Connector Type: ST bayonet connectors are specified here, which means this trunk is targeted at legacy ST-based patch panels or specific distribution hardware requiring ST interfaces. Verify your termination panels match ST before ordering — swapping connector types on a trunk is not field-serviceable.
- Plenum (OFNP) Rated Jacket: The OFNP flammability rating satisfies NEC plenum space requirements for air-handling spaces above drop ceilings and raised floors. Running fiber through plenum without OFNP-rated cable is a code violation in most commercial builds — this trunk eliminates that risk without requiring conduit as an alternative.
- Small-Diameter Trunk Construction (HD Flex): The QuickNet HD Flex sub-brand specifically targets reduced outer diameter versus standard-construction trunks. In high-density pathways and cable trays that are near capacity, a smaller cable OD improves fill ratio and airflow — relevant in any enterprise data center managing cable tray utilization budgets.
- Red Jacket Color: Red is a common convention for single-mode fiber identification in structured cabling standards (e.g., TIA-568 uses yellow for OS1/OS2 SM, but facility-specific color schemes often assign red to specific zones or networks). Confirm your site color scheme before deploying — the red jacket aids at-a-glance zone identification in multi-trunk cable trays.
- Indoor Rating: Rated for indoor environments; this trunk is not suitable for direct outdoor burial, aerial plant, or outdoor conduit runs exposed to weather. For indoor-to-outdoor or plenum-to-riser transitions, verify the appropriate hybrid or outdoor-rated assembly from the same family.
- Factory-Terminated with Pulling Eye: The stranded intermediate pulling eye on the A-end is a significant field convenience on 84-foot runs — it allows the cable to be pulled through conduit or cable tray without risk of connector damage during installation, then the pulling eye is cut away after routing.
Integration & Compatibility
This trunk is designed to integrate with fiber optic trunk systems using ST-interface patch panels, fiber distribution units, or zone enclosures. The QuickNet HD Flex platform is part of Panduit's broader end-to-end structured cabling infrastructure ecosystem, which includes matching panels, enclosures, and management accessories. Verify that your termination hardware accepts ST connectors — the majority of modern high-density panels use LC or MPO, so ST-terminated trunks target specific legacy or application-specific installations. Single-mode fiber (OS1/OS2) is compatible with single-mode transceivers and SFP modules operating at 1310 nm or 1550 nm wavelengths; confirm your active equipment is single-mode rated before deploying. For planning cable counts and pathway fills, consult a fiber cabling planning guide to size trunks correctly before ordering factory-terminated assemblies.
Frequently Asked Questions
Q: What connector type does the FY9WP77B005F084 use, and is it field-swappable?
A: This trunk ships with ST bayonet connectors. Factory-terminated trunk connectors are not field-swappable — the assembly is terminated and tested at the factory. Verify your patch panels and distribution hardware accept ST connectors before ordering.
Q: Is the FY9WP77B005F084 suitable for plenum spaces?
A: Yes. The jacket carries an OFNP (Plenum) flammability rating, which satisfies NEC requirements for installation in air-handling plenum spaces without requiring conduit as an alternative pathway.
Q: Can the FY9WP77B005F084 be used outdoors or in wet locations?
A: No. This assembly is rated for indoor use only. It is not suitable for direct burial, aerial installation, or outdoor conduit runs exposed to moisture or temperature extremes beyond standard indoor ranges.
Q: How many duplex connections does a 48-fiber trunk provide per end?
A: A 48-fiber trunk supports 24 duplex connections per end — enough to fully populate a standard 24-port duplex fiber patch panel at each termination point with a single cable pull.
Q: What does the red jacket color indicate on the FY9WP77B005F084?
A: The red jacket is the factory color for this assembly. Red is often used in facility-specific color-coding schemes to identify specific fiber zones or network segments. Confirm your site's cable color convention before deploying to ensure consistent identification practices.
Q: What is the pulling eye on the A-end used for?
A: The stranded intermediate pulling eye on the A-end allows the trunk to be pulled through conduit or cable tray without exposing the factory connectors to pulling tension or physical damage. The pulling eye is removed after the cable is routed to its final position.
The FY9WP77B005F084 is one of those assemblies you spec when you've done the math on field termination cost and decided factory-terminated is the only defensible choice. At 84 feet and 48 fibers, this QuickNet HD Flex trunk is sized for inter-row data center runs or telecom room cross-connects where pulling 24 individual jumpers would consume an installer's entire shift — and introduce 24 opportunities for a bad cleave or dirty connector.
Technical Highlights:
- OFNP Plenum Rating: This is the jacket rating that gets you through code inspection without running conduit in air-handling spaces — a real cost avoidance on large-scale data center builds where plenum pathways are the norm and conduit would add significant material and labor.
- 48-Fiber Single-Mode Count: Single-mode at 48 fibers per trunk means this assembly supports long-distance, high-bandwidth backbone runs between MDA and HDA, or building-to-building inter-connect over multimode-incompatible distances — assuming your active equipment is single-mode rated.
- Stranded Intermediate Pulling Eye (A-End): At 84 feet, you're likely pulling through conduit or a congested tray. The factory pulling eye protects all 48 ST connectors during the pull — without it, you're improvising a field pulling grip and risking connector damage on a high-cost assembly.
Deployment Considerations:
- ST connectors on a 48-fiber trunk are increasingly application-specific — most modern high-density panels have moved to LC or MPO. Audit your termination hardware carefully before procurement; this trunk does not fit LC or MPO panels without adapter modules that defeat the density benefit.
- Factory trunk lengths are fixed at 84 feet (25.6 m) — there is no field option to shorten. Measure the longest run in your pathway, add slack for service loops, and confirm this length fits before ordering. A trunk 6 feet short of its destination is a full replacement, not a field fix.
The FY9WP77B005F084 is the right call for data center builds or telecom room upgrades where OFNP compliance is required, ST-panel infrastructure is already in place, and the priority is rapid, error-free deployment of 48-fiber single-mode backbone segments without touching a cleaver.
