Panduit FY9WP77B005F068 48-Fiber Singlemode Plenum Trunk Cable Assembly
Overview
The Panduit FY9WP77B005F068 is a 48-fiber singlemode indoor trunk cable assembly from the QuickNet™ HD Flex sub-brand, purpose-built for pre-terminated fiber optic cabling infrastructure in data centers, telecommunications rooms, entrance facilities, and equipment distribution areas. At 68 feet (20.7 meters), this assembly ships factory-terminated and pull-ready, eliminating field splicing labor and dramatically compressing deployment timelines compared to cut-and-terminate approaches. The red jacket provides instant visual identification in high-density cable trays where color-coding discipline matters — especially in multi-zone or multi-tenant facilities.
Part of the broader Panduit structured cabling line, this trunk is designed for environments where cable congestion, fire safety compliance, and installation speed converge as hard requirements rather than nice-to-haves.
Key Features
- 48-Fiber Singlemode Core: Singlemode glass supports longer reach and higher bandwidth than multimode — relevant when trunks bridge IDF-to-MDF runs or span longer inter-rack distances. With 48 fibers in a single assembly, you're provisioning substantial port density in one pull, which reduces tray fill and simplifies future audits.
- Plenum (OFNP) Flammability Rating: OFNP-rated jacket is required by NEC in plenum air spaces — above drop ceilings and in raised floor environments used for air return. Installing a non-plenum cable in these spaces is a code violation that creates liability and rework. This assembly meets that bar from the factory, so there's no field substitution risk.
- ST Connectors: ST (straight-tip) bayonet connectors are specified here — a mature, widely-supported interface common in legacy enterprise and institutional fiber plants. If your panels, switches, or patch fields already use ST ports, this trunk drops in without adapter sleeves. If you're terminating into LC or SC panels, account for adapter modules before ordering.
- Pre-Terminated Factory Assembly: Factory termination means insertion loss and return loss are tested and guaranteed at the point of manufacture, not in the field under time pressure. For trunk cable assemblies feeding high-density switches or passive optical panels, that consistency matters — field-polished ST connectors can vary widely depending on technician skill and tooling condition.
- Pulling Eye on End A: The strain-relief pulling eye on End A is a practical installation detail: you can attach a pull string or fish tape directly to the assembly without improvising grip points on the connectors themselves, reducing the risk of connector damage during conduit or tray pulls.
- 68-Foot (20.7m) Fixed Length: At 68 feet, this trunk is sized for mid-span inter-rack or cross-room runs — longer than a standard patch cord but sized below the bulk spool range. Pre-cut length eliminates slack management headaches. Measure your actual run before ordering; trunk assemblies are not field-reterminated.
- Red Cable Jacket — QuickNet™ HD Flex: The red outer jacket is a QuickNet HD Flex standard color indicator for singlemode fiber. In a mixed-fiber environment where OS2 singlemode and OM3/OM4 multimode trunks coexist in the same tray, color-coded jackets let technicians confirm fiber type at a glance without tracing labels — a real operational benefit during moves, adds, and changes.
Integration & Compatibility
The FY9WP77B005F068 integrates into Panduit QuickNet HD Flex patch panel systems and any infrastructure accepting ST-type fiber connectors. It is suited for network infrastructure deployments including enterprise LAN backbone, data center horizontal and vertical cabling, and carrier-class telecommunications rooms. The OFNP rating ensures compatibility with plenum-rated infrastructure installations under NEC Article 770. Singlemode fiber is compatible with OS2 transceivers and active equipment specifying 9/125μm glass. Verify that your active equipment and panels match ST connector interfaces before deployment — ST is less common in newly-specified equipment than LC; adapter couplers are available but add insertion loss and a mechanical joint to the link budget.
Frequently Asked Questions
Q: Is the FY9WP77B005F068 suitable for outdoor or riser installations?
A: No. The FY9WP77B005F068 is rated for indoor use with a Plenum (OFNP) jacket. It is not rated for outdoor, direct burial, or riser (OFNR) applications. For outdoor or riser runs, a different cable rating and jacket type is required.
Q: What fiber type does the FY9WP77B005F068 use — singlemode or multimode?
A: This assembly uses singlemode fiber (OS2, 9/125μm). Singlemode supports longer reach and higher bandwidth than multimode. Make sure your transceivers and active equipment are specified for singlemode before deploying this trunk.
Q: Can the FY9WP77B005F068 be field-reterminated if the length is wrong?
A: Pre-terminated trunk assemblies are not designed for field retermination. Measure your actual run carefully before ordering. The 68-foot (20.7m) fixed length is set at the factory.
Q: What connector interface does this trunk use at each end?
A: Both ends use ST (straight-tip bayonet) connectors. If your panels or switches use LC or SC ports, you will need adapter modules — factor those into your link budget, as each adapter adds an additional mechanical interface.
Q: Is this trunk assembly compliant with NEC plenum requirements?
A: Yes. The OFNP (Optical Fiber Nonconductive Plenum) rating meets NEC Article 770 requirements for installation in plenum air-handling spaces such as above drop ceilings and under raised floors used for air return.
Q: What does the red jacket color signify on the FY9WP77B005F068?
A: In the Panduit QuickNet HD Flex system, red identifies singlemode fiber. In mixed-fiber environments where singlemode and multimode trunks share the same trays, the color coding allows technicians to confirm fiber type visually without label tracing.
The FY9WP77B005F068 is a 48-fiber singlemode OFNP plenum trunk at 68 feet — a spec combination that signals a specific deployment context: you're running pre-terminated infrastructure through a plenum air space, you need color-coded singlemode identification, and you're working in a Panduit QuickNet HD Flex ecosystem. That's a meaningful set of constraints that narrows this down from a generic trunk to a purpose-built assembly.
Technical Highlights:
- 48-Fiber Density: Consolidating 48 singlemode fibers into a single factory-terminated pull is a real time and labor saving on dense IDF-to-MDF backbone runs — you're committing one pull event instead of multiple smaller-count trunks, and every fiber arrives pre-tested.
- OFNP Plenum Rating: OFNP isn't optional in above-ceiling or raised-floor air-return paths — it's an NEC Article 770 hard requirement. Having it factory-built into the assembly removes the risk of a technician substituting a riser-rated trunk under schedule pressure.
- ST Connector Interface: ST bayonet connectors on this assembly mean it's targeting installed base compatibility, not a greenfield design. If you're specifying new panels today, verify ST is your standard — LC is the current dominant interface in high-density enterprise fiber.
Deployment Considerations:
- Measure twice before ordering: 68 feet (20.7m) is a fixed factory length. Pre-terminated trunks cannot be reterminated in the field — if your run is 55 feet, you'll manage 13 feet of slack; if it's 72 feet, you'll need a different assembly.
- ST to non-ST mismatches require adapter couplers that each introduce an additional mechanical interface and incremental insertion loss — factor this into your link budget calculation before finalizing the order if your panels are LC or SC.
This assembly is well-suited for enterprise data centers and carrier-class telecom rooms retrofitting or expanding a Panduit QuickNet HD Flex backbone where ST panels are already in place, OFNP compliance is enforced, and 48-fiber density per pull is the operating target.
