Panduit FY9TP55A005F100 QuickNet HD Flex 12-Fiber ST Singlemode Pre-Terminated Trunk Cable

Overview

The Panduit FY9TP55A005F100 is a factory pre-terminated 12-fiber singlemode trunk cable from the Panduit QuickNet HD Flex lineup, spanning 100 feet (30.5 meters) with ST connectors on each end. It's purpose-built for structured cabling environments where installation speed matters: data centers, telecommunications rooms, entrance facilities, and equipment distribution areas where pulling and terminating fiber on-site would cost hours that a pre-tested assembly can recover. If your team is racing to commission a new MDA or IDA zone, or bridging a telecom room to distribution gear, this assembly deploys the fiber segment without a fusion splice or field termination in sight.

The QuickNet HD Flex branding signals a design intent toward flexible routing in high-density spaces — relevant when you're navigating cable trays, overhead routes, or tight bend radii inside enclosed racks. The pre-terminated fiber trunk cable category as a whole trades field-termination flexibility for factory-controlled insertion loss and reflectance, and that trade is almost always the right call in a structured data center deployment.

Key Features

• ST Connector Termination: ST connectors are a bayonet-style interface still active in legacy telecom rooms, military infrastructure, and older enterprise fiber plants. If your patch panels or transceivers are ST-keyed, this assembly eliminates the need for field-terminated pigtails or hybrid adapters — plug straight in without an intermediate coupling. If your environment is LC or SC, this is the wrong assembly; review your patching infrastructure before ordering.
• Singlemode Fiber (SM): Singlemode supports long-haul runs at full bandwidth — no modal dispersion ceiling, no distance cap that multimode would impose. For 100ft inter-room or inter-facility links in enterprise campuses or carrier-class telecom rooms, singlemode is the future-proof choice when you plan to run 10G, 40G, or 100G transceivers down the road.
• 12-Fiber Count: A 12-fiber trunk handles moderate-density interconnects — enough for six duplex channels or twelve simplex paths simultaneously. This fiber count is practical for connecting a small IDF to a core switch stack or linking two distribution frames without over-cabling a path that doesn't need 24F or 48F density.
• 100 ft / 30.5 m Length: At exactly 100 feet, this run suits inter-rack and inter-room segments within a single facility floor. It's long enough to bridge equipment bays that span a full data hall row, but not a substitute for building-riser or cross-campus infrastructure — verify your route measurement before committing to this length.
• Factory Pre-Terminated Assembly: Factory termination means consistent, tested end-face geometry and controlled polish — no field-variable insertion loss from a technician's splice quality. Pre-terminated assemblies from this product family are designed to support rapid deployment timelines, which is the primary operational justification for their premium over field-terminated alternatives.
• QuickNet HD Flex Platform: The HD Flex sub-brand from Panduit indicates a design optimized for high-density cabling environments where routing flexibility is constrained. This matters in fully-populated data center rows where cable management has no margin for rigid or oversized assemblies.

Integration & Compatibility

The FY9TP55A005F100 installs into any ST-keyed fiber patch panel, wall-mount enclosure, or transceiver interface. Singlemode fiber is compatible with singlemode-capable transceivers (SFP, SFP+, QSFP variants specified for OS1/OS2 single-mode). Verify transceiver wavelength compatibility — 1310nm and 1550nm are the standard singlemode windows, and your active equipment must match. This assembly does not include adapter panels, splice trays, or enclosures; pair it with compatible Panduit or third-party fiber enclosures sized for ST connectors. For structured cabling builds following ANSI/TIA-568 or ISO/IEC 11801, confirm that ST interfaces are specified in your design — newer standards increasingly favor small-form-factor connectors (LC, MPO).

Frequently Asked Questions

Q: What connector type is on the FY9TP55A005F100?

A: Both ends are terminated with ST connectors. ST uses a bayonet-style coupling common in legacy telecom and enterprise fiber installations. If your patch panels or equipment use LC, SC, or MPO interfaces, this assembly is not a direct fit.

Q: Is the FY9TP55A005F100 singlemode or multimode?

A: Singlemode (SM). Singlemode fiber supports long distances and high bandwidth without the modal dispersion limits of multimode. It requires singlemode-compatible transceivers and active equipment.

Q: What is the exact length of the FY9TP55A005F100?

A: 100 feet (30.5 meters). Measure your route carefully before ordering — this is a fixed-length factory assembly and cannot be extended or shortened in the field.

Q: How many fibers are in the FY9TP55A005F100?

A: 12 fibers. This supports six duplex channels or twelve simplex paths depending on your connector mapping and transceiver configuration.

Q: What environments is the FY9TP55A005F100 designed for?

A: Data centers, telecommunications rooms, entrance facilities, and equipment distribution areas requiring pre-terminated fiber infrastructure for rapid deployment — per the application specification from the manufacturer.

Q: Does the FY9TP55A005F100 come with patch panels or enclosures?

A: No. This is a trunk cable assembly only. Patch panels, adapter plates, and enclosures are sold separately and must be specified for ST connector compatibility.

The FY9TP55A005F100 comes up in conversations where a team needs to close a structured cabling segment fast without pulling a fusion splicer onto the floor — the 100ft (30.5m) factory-terminated ST singlemode assembly is the kind of trunk you grab when the route is measured, the patch panels are ST-keyed, and the job needs to be done today. That said, ST is the detail that makes or breaks the fit here: before this gets added to a purchase order, verify that both endpoint panels are ST-style bayonet — mixing connector families without a hybrid coupler is a day-one troubleshooting call you don't want.

Technical Highlights:

• 12-Fiber Count at 100ft: Twelve fibers over a 30.5m run gives you six duplex channels in a single routed assembly — sufficient to connect a small IDF switch stack to a core distribution frame without overspending on a 24F trunk where half the fibers go unused.
• Singlemode Glass: SM fiber eliminates the distance and bandwidth ceiling that OM3/OM4 multimode would impose — 10G, 25G, or 100G transceivers over this run length won't be constrained by the fiber itself, only by the active equipment at each end.
• QuickNet HD Flex Platform: The HD Flex designation indicates routing flexibility engineered for dense cable management environments — relevant when you're threading through occupied trays or navigating tight bend-radius zones inside enclosed rack rows.

Deployment Considerations:

• This is a fixed-length assembly at exactly 100ft — there's no field-adjustable slack beyond what you coil in the tray. Measure the physical route (including vertical drops and overhead bends) before committing; a route that runs 105ft needs a different SKU, not a stretched cable.
• ST connectors require a quarter-turn bayonet lock to seat fully — in high-vibration environments or dense panels where techs are working adjacent ports blind, verify each connection is fully seated and locked before commissioning. A half-seated ST looks connected but will fail optical testing.

This assembly is a strong fit for a telecom room refresh or a new MDA build in an enterprise data center where the existing infrastructure is ST-keyed and the team is on a tight commissioning schedule — factory termination removes field-variable insertion loss from the equation and gets the fiber segment qualified and patched in a single visit.
