Panduit FY9WP77B005F040 48-Fiber Singlemode Plenum Trunk Cable Assembly
Overview
The Panduit FY9WP77B005F040 is a factory-terminated, 48-fiber singlemode trunk cable assembly from the QuickNet™ HD Flex product line, designed for structured cabling deployments in data centers, telecommunications rooms, entrance facilities, and equipment distribution areas. At 40 feet (12.2 meters), this trunk arrives on-site pre-terminated with ST connectors on both ends, eliminating field splicing labor and the risk of manual termination errors in active data center environments.

Key Features
- 48-Fiber Singlemode Core: 48 individual singlemode fibers in a single jacket — enough capacity to serve an entire data center cabinet row without multiple cable runs. Singlemode glass supports long-reach wavelengths (OS2 characteristics), which matters when you're bridging MDA to HDA runs or connecting entrance facilities to equipment rooms across larger campus distances.
- Plenum (OFNP) Flammability Rating: Rated OFNP, this cable is code-compliant for installation in plenum air-handling spaces without conduit. That means you can run it above drop ceilings or through raised-floor plenums in commercial buildings without requiring riser or conduit alternatives — a meaningful factor when working in occupied facilities under NEC Article 770.
- ST Connector Terminations: Both ends ship terminated with ST (straight tip) bayonet-style connectors. ST interfaces are still widely deployed in telecom rooms, campus fiber distribution frames, and legacy enterprise backbones. Confirm your patch panels and equipment ports before ordering — if your infrastructure has migrated to LC or MPO, a different trunk variant is required.
- QuickNet™ HD Flex Sub-Brand: The QuickNet HD Flex platform is Panduit's high-density, flexible-deployment fiber system. Pre-tested at the factory means each connector is already inspected and documented — no field test equipment needed at install, which accelerates commissioning windows in high-density cabling jobs where dozens of trunks terminate in a single shift.
- 40-Foot Fixed Length (12.2m): The 40ft run is purpose-suited for same-room or adjacent-bay cabling — data center row-to-row, MDA to adjacent HDA, or telecom room to entrance facility in a compact building footprint. Fixed-length pre-terminated assemblies eliminate field waste and produce consistent, repeatable slack management in cable trays.
- Red Jacket Color: The red outer jacket aids in visual cable management and plant documentation. Many data center standards use color to differentiate fiber type, circuit type, or zone. Red can serve as a singlemode identifier or zone marker depending on your site's color convention — confirm against your site's cabling standard before assigning meaning to color.
- Pulling Eye Strain Relief: The description references a stranded inner pulling-eye end (End A). A factory-installed pulling eye on End A allows the trunk to be installed through conduit or cable trays using a pull string without stressing the connectors or the jacket — preserving factory optical performance through the installation process.
- Pre-Terminated for Rapid Deployment: Field termination of 48 fibers per run — particularly ST — is time-intensive and requires specialized equipment and trained technicians. A pre-terminated assembly converts that labor into a plug-and-play installation step, reducing installation time per run from hours to minutes and removing the primary source of on-site fiber loss variation.
Integration and Compatibility
The FY9WP77B005F040 is designed for integration into Panduit's fiber optic trunk cable infrastructure, including QuickNet cassette modules and high-density patch panels that accept ST-style adapters. Verify that your patching hardware and equipment ports — switches, transceivers, or active gear — accept ST bayonet connectors before specifying this trunk. For environments that have standardized on LC-duplex or MPO/MTP interfaces, Panduit offers alternate trunk variants in the QuickNet HD Flex line with compatible termination styles.
This trunk is suited for OS2 singlemode applications. Confirm fiber type compatibility with your transceivers — short-reach SFPs specified for multimode OM3/OM4 will not perform correctly on singlemode glass. If you're planning a full high-density build, review our fiber cabling selection guide to match trunk counts, connector styles, and reach requirements before procurement.
For complete zone cabling builds, this trunk pairs with Panduit patch panels and cassette housings in telecommunications rooms and data center distribution frames.
Frequently Asked Questions
Q: What fiber type does the FY9WP77B005F040 use — singlemode or multimode?
A: This is a singlemode (SM) trunk cable assembly. It is not compatible with multimode transceivers or short-reach optics rated for OM3/OM4 glass. Verify your active equipment ports are specified for OS2 singlemode before installing this trunk.
Q: What connector type is on the FY9WP77B005F040?
A: Both ends are factory-terminated with ST (straight tip) bayonet-style connectors. If your patch panels or equipment interfaces use LC, SC, or MPO/MTP connectors, this trunk is not a direct fit — select the appropriate QuickNet HD Flex variant for your connector type.
Q: Is the FY9WP77B005F040 approved for plenum air-handling spaces?
A: Yes. The cable carries an OFNP (Optical Fiber Nonconductive Plenum) flammability rating, making it NEC-compliant for installation in plenum ceiling and raised-floor air-handling spaces without conduit in most commercial building applications. Always confirm with your local AHJ.
Q: What is the exact length of the FY9WP77B005F040?
A: The assembly is 40 feet (12.2 meters) in overall length. This is a fixed-length pre-terminated trunk — it cannot be field-extended or shortened without losing the pre-terminated assembly's factory-tested performance.
Q: How many fibers does the FY9WP77B005F040 contain?
A: The trunk contains 48 individual singlemode fibers, providing 48 discrete fiber paths in a single jacket — suitable for high-density MDA-to-HDA or telecom room distribution runs serving multiple cabinets or equipment zones.
Q: What does the pulling eye on End A allow during installation?
A: End A is fitted with a stranded inner pulling eye, which allows the trunk to be pulled through conduit or routed through cable trays using a standard fish tape or pull string without applying tensile stress directly to the connectors or the cable jacket. This preserves factory insertion loss values through the installation process.
The FY9WP77B005F040 is the trunk I reach for when a data center job has tight installation windows and no tolerance for field-termination variables. The 48-fiber singlemode construction in a single OFNP-rated jacket handles serious zone distribution capacity — think MDA serving 6 to 8 cabinets per run — and the factory ST terminations on both ends mean you're plugging in, not polishing, the moment the cable is routed.
Technical Highlights:
- 48-Fiber Capacity: 48 singlemode paths in one 40-foot jacket is a meaningful density advantage over lower-count trunks in tight cable trays — fewer cable runs, fewer tray fill calculations, and cleaner documentation for future MAC work.
- OFNP Plenum Rating: Eliminates the conduit requirement in air-handling spaces under NEC 770. In an occupied commercial building where plenum above-ceiling routing is the only practical path, OFNP isn't optional — it's the only compliant choice.
- Factory Pulling Eye (End A): The stranded pulling eye on End A is a real install time-saver when you're threading through J-hooks or conduit segments. It distributes pull force across the cable structure rather than the connectors, so the factory insertion loss spec survives the installation intact.
Deployment Considerations:
- ST connectors are a legacy interface. Before specifying the FY9WP77B005F040, verify every patch panel and equipment port in the run accepts ST bayonet — a single LC or MPO panel in the path means this trunk doesn't fit and you need a different variant.
- At 40 feet fixed, there's no field adjustment. Measure the actual cable path — not the straight-line distance — including tray routing, bend radius at corners, and service loop requirements before confirming this length. Coming up 3 feet short on a pre-terminated trunk means a change order.
This trunk is the right call for a greenfield data center telecom room build where ST-based distribution frames are already specified, plenum routing is required, and the project schedule won't tolerate field termination delays on a 48-fiber count run.
