Panduit FR9TP77Y001F055 12-Fiber Singlemode Plenum Interconnect Cable, 55ft

Overview

The Panduit FR9TP77Y001F055 is a 12-fiber singlemode plenum-rated interconnect cable cut to 55 feet — a purpose-built trunk for backbone fiber runs in air-handling spaces where fire code mandates low-smoke, flame-retardant jacket materials. If you're pulling fiber above a drop ceiling in a commercial building or through an open-air plenum, this cable eliminates the code compliance question before the job starts. Panduit's structured cabling line is engineered to meet the physical infrastructure demands of enterprise and data center environments, and this assembly fits squarely into that portfolio.

Key Features

• 12-Fiber Count: Twelve strands in a single jacket means you can support multiple parallel high-bandwidth links — backbone aggregation, parallel 40G/100G breakout, or future capacity — without pulling a second cable. Plan your conduit fill now and avoid the cost of returning to trench or re-pull later.
• Singlemode Fiber: Singlemode glass supports transmission distances that multimode can't touch. For inter-building runs, campus backbones, or long in-building risers, singlemode is the correct architecture — it keeps your options open for 10G, 40G, and 100G transceivers at distance without re-pulling fiber.
• Plenum (CMP) Rating: The plenum jacket meets CMP fire code requirements for installation in air-handling spaces. Using a riser or non-rated cable in a plenum space is a code violation — this cable is the right answer for those environments, and an inspector will not flag it. Check your local AHJ requirements, but CMP covers the vast majority of commercial plenum installations.
• 55-Foot Pre-Cut Length: A 55ft assembly spans typical inter-rack distances in mid-size data centers and long horizontal office backbone runs without splicing or field-termination. Pre-terminated assemblies eliminate field polishing errors and reduce installation time versus pulling raw fiber and terminating on site.
• Commercial-Grade Construction: Panduit fiber assemblies are manufactured to commercial interconnect standards — suitable for structured cabling systems in enterprise, healthcare, education, and government facilities where documentation and traceability matter.

Integration & Compatibility

The FR9TP77Y001F055 is designed to integrate with Panduit's fiber optic cabling infrastructure including patch panels, fiber enclosures, and cable management pathways. Singlemode interconnect assemblies like this one pair with LC, SC, or MPO-terminated equipment depending on connector type — confirm the connector style on both ends before ordering. This cable is appropriate for use with fiber-uplink network switches and media converters in structured cabling deployments. For projects requiring a full fiber backbone plan, review the network and PoE planning guide to size cable counts and pathway capacity correctly. Pair with compatible fiber patch panels to complete the interconnect system.

Frequently Asked Questions

Q: Is the FR9TP77Y001F055 rated for installation in air-handling plenum spaces?

A: Yes. This cable carries a plenum (CMP) rating, which meets fire code requirements for installation in air-handling ceiling and floor spaces. It is the correct choice where local code prohibits riser or general-purpose rated cable.

Q: What fiber type does the FR9TP77Y001F055 use — multimode or singlemode?

A: Singlemode. Singlemode fiber supports longer transmission distances than multimode and is compatible with singlemode-spec transceivers for 10G, 40G, and 100G applications.

Q: How many fibers are in the FR9TP77Y001F055?

A: 12 fibers. This allows multiple parallel links or breakout configurations within a single cable jacket.

Q: What is the cable length of the FR9TP77Y001F055?

A: 55 feet (approximately 16.8 meters). It is a pre-cut factory assembly — not a bulk spool.

Q: Can this cable be used for inter-building campus runs?

A: Singlemode fiber supports the distance requirements of inter-building runs. However, confirm the specific connector type and verify that both terminal endpoints accept the connector style on this assembly before purchasing.

Marty Allison

The FR9TP77Y001F055 is the assembly I reach for when a project spec calls for plenum-rated singlemode in an enterprise backbone and the run distance lands around 55 feet — the pre-terminated length eliminates field polishing risk in spaces where going back to re-terminate is expensive and disruptive.

Technical Highlights:

• Plenum (CMP) Jacket: Mandatory for any fiber run through air-handling spaces — skipping this on a commercial build is a code violation that will surface at inspection or after an incident. CMP-rated jacket handles the flame-spread and smoke requirements that riser cable cannot.
• 12-Fiber Count: Twelve strands give you enough capacity to run multiple 10G or parallel 40G links in a single pull, leaving headroom for future adds without re-entering the ceiling or conduit.
• Singlemode Glass: Singlemode is distance-agnostic for the ranges this cable is used in — it keeps 100G upgrade paths open without a fiber re-pull, which matters in buildings where conduit access is locked down after initial construction.

Deployment Considerations:

• Confirm connector type on both ends before ordering — singlemode interconnect assemblies come in LC, SC, and MPO variants, and a connector mismatch means the assembly goes back rather than into the pathway.
• At 55 feet this is a fixed-length pre-terminated assembly, not a field-cuttable bulk cable. Measure your run with slack allowance before purchasing — if the actual distance is 60+ feet, size up to the next available length rather than forcing a tight fit.

This assembly is the right specification for enterprise data center inter-rack backbone and commercial building riser-to-IDF runs where fire code, distance, and bandwidth headroom all need to be right from day one — not corrected after the ceiling tiles go back up.
