Panduit FY9WP77B005F082 48-Fiber Single-Mode Indoor Plenum Trunk Cable Assembly

Overview

The Panduit FY9WP77B005F082 is a 48-fiber single-mode indoor trunk cable assembly from the Panduit QuickNet HD Flex line — engineered for data centers, telecommunications rooms, entrance facilities, and equipment distribution areas where speed of deployment and fiber density matter. At 82 feet (25 meters), this pre-terminated assembly arrives pull-ready with a strain-relief pulling eye on the lead end, so your team can run it through conduit or cable management without risking connector damage during installation. The red jacket makes polarity identification straightforward in congested pathway environments where color discipline prevents misdirected connections.

Pre-terminated fiber trunk assemblies like this one eliminate field termination labor entirely — no fusion splicing, no polishing, no on-site testing of individual connectors. For a 48-fiber count, that's a significant reduction in installation time and the variability that comes with field craftsmanship. The FY9WP77B005F082 ships factory-tested, which also means insertion loss is characterized before it ever touches your floor.

Key Features

• 48-Fiber Single-Mode Construction: Single-mode fiber supports transmission distances far beyond multi-mode — critical in enterprise campuses, colocation facilities, and any deployment where runs exceed the 300–550m limits of OM4/OM5. If your architecture uses 10G/40G/100G optics over long backbone runs, single-mode is the correct fiber type to specify.
• ST Connector Termination: ST connectors are a bayonet-style interface with broad legacy support across patch panels, switches, and media converters. If your existing infrastructure is standardized on ST, this assembly integrates without adapter sleeves that introduce additional insertion loss. Confirm your chassis accepts ST before ordering — adapters are available but add bulk and loss.
• Plenum (OFNP) Flammability Rating: The OFNP rating means this cable is code-compliant for installation in air-handling plenum spaces — above drop ceilings or below raised floors where building HVAC circulates. Substituting a riser-rated (OFNR) or non-rated cable in a plenum environment is a code violation in most jurisdictions. If your pathway is plenum-designated, this is a required specification, not optional.
• 82-foot (25-meter) Factory Length: The 82ft run length targets inter-rack and inter-row backbone connections in mid-to-large data center floor plans, as well as structured cabling home-run segments in telecommunications rooms. Measure twice — pre-terminated trunk assemblies are not field-shortenable without destroying the factory-terminated end.
• Red Jacket — Polarity and Zone Identification: Color-coded infrastructure is standard practice in high-density environments. Red is commonly assigned to single-mode fiber in TIA-568 color conventions, making polarity tracing and zone identification faster during moves, adds, and changes. Consistent color discipline reduces mis-patch incidents during network changes.
• Strain-Relief Pulling Eye on Lead End: The integrated pulling eye distributes pulling tension across the cable jacket rather than the fiber or connector ferrules. This is the right way to pull trunk assemblies through conduit — field teams that skip this and pull by the connector body risk cracking ferrules and creating latent insertion loss that doesn't show up until load testing.
• QuickNet HD Flex Sub-Brand: The HD Flex designation indicates high-density, flexible design — this product family is built for structured cabling environments where pathway fill rates are a concern and cable management flexibility matters. The small-diameter construction of these trunks is specifically designed to improve bend radius compliance in congested trays.

Integration and Compatibility

The FY9WP77B005F082 is designed to integrate with Panduit QuickNet HD Flex patch panels and cassette-based fiber distribution systems, but the ST connector interface is an open standard compatible with any ST-port chassis from any manufacturer. Pair this trunk with compatible fiber patch panels on both ends to complete the backbone segment. Verify that both termination points accept ST connectors — many modern high-density chassis have migrated to LC or MPO interfaces, so compatibility confirmation before ordering prevents a costly mismatch.

For data center backbone applications running 10GBase-LR, 40GBase-LR4, or 100GBase-LR4, single-mode fiber is the correct medium. This assembly does not support short-reach multi-mode optics (SR variants) — those require OM3/OM4/OM5 fiber. Confirm your transceiver specifications against fiber type before specifying.

Frequently Asked Questions

Q: What is the fiber type in the FY9WP77B005F082 — OS1 or OS2?

A: The FY9WP77B005F082 is specified as single-mode fiber. The source evidence does not explicitly distinguish OS1 vs. OS2 sub-category. For indoor plenum installations at 25 meters, either OS1 or OS2 will perform within spec for standard SMF transceivers — confirm with Panduit's product documentation if your application requires OS2 specifically.

Q: Can I cut the FY9WP77B005F082 to a shorter length on-site?

A: No. This is a factory pre-terminated trunk cable assembly. Cutting the cable destroys the factory-installed connector on that end. If you need a shorter run, specify the appropriate length at time of order. Panduit offers QuickNet HD Flex trunks in multiple factory lengths.

Q: Is the FY9WP77B005F082 rated for plenum air-handling spaces?

A: Yes. It carries an OFNP (Plenum) flammability rating, which meets NEC requirements for installation in air-handling plenum spaces such as above drop ceilings and below raised access floors used for HVAC circulation.

Q: What connector type does the FY9WP77B005F082 use, and is it compatible with LC or MPO patch panels?

A: The FY9WP77B005F082 uses ST connectors. It is not directly compatible with LC or MPO interfaces without adapter sleeves. If your patch panel infrastructure uses LC or MPO, this is not the correct assembly — specify a trunk with matching connector types to avoid adapter-induced insertion loss penalties.

Q: What is the overall length of the FY9WP77B005F082 in both feet and meters?

A: The assembly is 82 feet (25 meters) overall length, factory-terminated.

Q: What does the pulling eye on the lead end do, and is it safe to pull this trunk through conduit?

A: The strain-relief pulling eye on the lead end distributes conduit-pull tension across the cable jacket and strength members, protecting the factory-installed connector ferrules from mechanical stress during installation. This assembly is designed for conduit pulling when using the pulling eye correctly — never pull by gripping the connector body directly.

The FY9WP77B005F082 is one of those assemblies that earns its place in a deployment not through exotic specs but through execution discipline — 48 fibers, factory-terminated with ST connectors, OFNP-rated, at a 25-meter run length that fits the inter-row and backbone segments you're actually measuring on most raised-floor data center builds. The pulling eye on the lead end is detail that matters: I've seen field teams crack ferrules pulling by the connector body on trunk assemblies that didn't have it, and you don't find that damage until you're doing insertion loss testing at 2am during a cutover.

Technical Highlights:

• OFNP Plenum Rating: Mandatory — not optional — if your pathway travels through air-handling space. Substituting riser-rated cable in a plenum zone is a code violation that fails inspection and creates fire liability. This assembly eliminates that risk for the 82ft segment.
• 48-Fiber Single-Mode Construction: Single-mode fiber at 25 meters is infrastructure-forward thinking — you're not buying capacity you need today, you're buying headroom for 100G and 400G optics on the same physical plant when you upgrade transceivers. Multi-mode at this density would lock you out of long-distance backbone extensions later.
• ST Connector Interface: ST is a mature, widely-supported standard. In environments where the existing chassis is ST-native, this assembly installs without adapter sleeves that add 0.2–0.5dB insertion loss per interface pair. If your chassis is LC or MPO, this is the wrong SKU — match your connector family before ordering.

Deployment Considerations:

• Measure the actual routed pathway — not straight-line distance — before committing to the 82ft factory length. Add service loop allowance (typically 3–5ft per end) to your measurement. A trunk that comes up 4 feet short requires an adapter or a full replacement assembly.
• ST connectors require a quarter-turn bayonet lock to seat properly. In high-density panels where fingers barely fit, an improperly seated ST connector looks connected but shows elevated insertion loss. Build a post-installation insertion loss test into your acceptance criteria, not an afterthought.

This assembly is the right specification for a telecommunications room backbone segment or data center inter-row run in a facility that standardized on ST-port fiber panels and needs OFNP compliance for plenum pathway routing — particularly in colocation environments where the build-out pace requires pre-terminated infrastructure to keep installation crews moving.
