Panduit FY9WP77B005F075 48-Fiber Single-Mode Plenum Trunk Cable Assembly
Overview
The Panduit FY9WP77B005F075 is a factory-terminated, 48-fiber single-mode indoor trunk cable assembly from the Panduit QuickNet™ HD Flex line — built for data centers, telecommunications rooms, entrance facilities, and equipment distribution areas where speed of deployment and fiber density matter. At 75 feet (22.9 m), this assembly arrives fully tested and ready to pull, eliminating field termination and the rework cycles that come with it. The red jacket makes it immediately identifiable on the cable tray as a single-mode run, a small but meaningful detail when you're managing dozens of trunks in a high-density backbone.
If you're building or expanding a fiber optic cable infrastructure in a plenum-rated environment, this assembly satisfies OFNP flammability requirements out of the box — no additional conduit or innerduct needed for air-handling plenum spaces. The ST connector interface suits installations where legacy patch panels or equipment still relies on ST terminations, which remains common in certain enterprise and campus backbone scenarios.
Key Features
- 48-Fiber Single-Mode Core: Moving 48 fibers through a single trunk pull dramatically reduces ladder tray and conduit fill versus running individual cables. In a data center backbone context, that density advantage compounds quickly — one trunk replacing 48 separate pulls is a real labor and pathway savings, especially in congested overhead runs.
- Pre-Terminated Assembly with Pulling Eye End: The strain-relieved pulling eye end lets you pull this assembly through conduit or cable tray using standard fish tape or pull cord without loading the fiber or connectors. Field termination is eliminated; you connect at both ends and you're done. That's where most fiber installation risk lives — and this removes it entirely.
- OFNP Plenum Flammability Rating: Rated for installation in air-handling plenum spaces without conduit. In most commercial builds, plenum spaces above drop ceilings and under raised floors are the primary horizontal and backbone pathways. An OFNP-rated trunk keeps you code-compliant without the cost or space penalty of running everything in conduit.
- 75 ft (22.9 m) Run Length: Sized for mid-span backbone runs — from a main distribution area to an intermediate distribution frame, or across a mid-size data center floor. At 22.9 m, you're well within single-mode loss budgets for virtually any application this cable class would serve. No splicing, no connectorization in the field.
- ST Connector Interface: ST connectors are a push-and-twist bayonet style, familiar in enterprise and campus installations and still present on a range of fiber patch panels and active equipment. If your termination points are ST-based, this assembly eliminates the need for adapter sleeves or hybrid patch cords at the panel.
- Red Cable Jacket: Red is the ANSI/TIA-568 designation color for single-mode fiber. A red jacket on every single-mode trunk keeps your fiber plant visually organized at a glance — important during adds, moves, and changes when the wrong fiber pull can cascade into a much larger outage.
- QuickNet™ HD Flex Sub-Brand: The HD Flex designation indicates this is part of Panduit's high-density flexible trunk system. HD Flex trunks are designed to integrate with QuickNet patch panel and cassette hardware, supporting modular, scalable structured cabling architectures that can be reconfigured without re-terminating the backbone.
Integration & Compatibility
The FY9WP77B005F075 is designed to plug into Panduit QuickNet HD Flex-compatible modules, cassettes, and patch panels. On the equipment side, the ST connector interface works with any fiber patch panel port or transceiver cage that accepts ST terminations — a broadly deployed standard across enterprise switching, passive optical infrastructure, and legacy campus backbone installations.
For deployments transitioning to higher-density LC or MPO panels, ST-to-LC or ST-to-MPO hybrid patch cords can bridge the gap at the panel side without replacing the backbone trunk. Single-mode fiber also future-proofs the run for higher-bandwidth wavelengths — this cable will carry 10G, 40G, or 100G transceivers without the fiber plant becoming the bottleneck, provided the active equipment and connectors support those speeds.
Always verify that the termination panels at both ends of the run are rated for and physically accept ST simplex connectors before ordering. If your panels are MPO-based, you will need a different trunk assembly. Consult your fiber installation planning guide to confirm trunk type and polarity scheme before cutting purchase orders on pre-terminated assemblies.
Frequently Asked Questions
Q: What connector type does the FY9WP77B005F075 use at both ends?
A: This assembly uses ST connectors. ST is a push-and-twist bayonet connector style. Both ends of this trunk terminate in ST connectors, making it suitable for patch panels and equipment ports that accept ST fiber terminations.
Q: Is the FY9WP77B005F075 rated for plenum air-handling spaces without conduit?
A: Yes. This cable carries an OFNP (Optical Fiber Nonconductive Plenum) flammability rating, which qualifies it for installation in plenum air-handling spaces without conduit or innerduct under the NEC.
Q: What is the fiber count and type in this trunk assembly?
A: The FY9WP77B005F075 contains 48 single-mode fibers. Single-mode fiber supports longer transmission distances and higher bandwidth applications compared to multimode, and is color-coded red in this assembly per standard TIA-568 conventions.
Q: Is this trunk compatible with Panduit QuickNet HD Flex panels and cassettes?
A: Yes. This assembly is part of the Panduit QuickNet™ HD Flex product line and is designed to integrate with compatible QuickNet HD Flex modules, cassettes, and patch panel hardware.
Q: Can this assembly be pulled through conduit during installation?
A: Yes. The assembly includes a strain-relieved pulling eye end that allows it to be pulled through conduit or cable tray using standard pull cord or fish tape without stressing the fiber or connectors.
The FY9WP77B005F075 is one of those assemblies that earns its price on labor savings alone. At 75 feet with 48 single-mode fibers, factory-terminated and pulling-eye-equipped, you're looking at a trunk that a two-person team can install in a fraction of the time required to field-terminate 48 individual fibers — and with zero splicing loss variability to troubleshoot afterward.
Technical Highlights:
- OFNP Plenum Rating: Qualifies for open-air plenum installation in commercial buildings without conduit. In a typical multi-floor enterprise build, this directly reduces material cost (no innerduct) and speeds the pull schedule.
- 48-Fiber Single-Mode, 75 ft (22.9 m): Single-mode at this fiber count handles backbone runs between MDA and IDA in a mid-size data center floor without approaching any practical distance or bandwidth ceiling for current or near-future active equipment.
- ST Connector Interface: Pre-terminated with ST connectors — the right choice when your termination panels are ST-based. Eliminates field polishing, connector-loss variation, and the need for hybrid patch cords at the panel.
Deployment Considerations:
- Verify ST connector compatibility at both termination panels before the assembly ships. Pre-terminated trunks cannot be re-terminated on-site without specialized equipment — ordering the wrong connector type means returning the assembly.
- The red jacket identifies this as single-mode per TIA-568 color coding. If your installation mixes single-mode and multimode trunks on shared trays, the red jacket is your first line of defense against cross-connects during MACs (moves, adds, changes). Enforce color discipline on the panel side as well.
This assembly is the right call for structured cabling backbones in commercial data centers and enterprise telecommunications rooms where the termination points are already ST-based and where OFNP compliance is a building code requirement — not a nice-to-have.
