Panduit FY9AP77A005M050 50M Single-Mode 144-Fiber Pre-Terminated ST Trunk Cable
Overview
The Panduit FY9AP77A005M050 is a 50-meter (164.1 ft), 144-fiber single-mode pre-terminated trunk cable from the Panduit QuickNet HD Flex product family. Designed for environments where installation speed and fiber density matter most — data centers, telecommunications rooms, entrance facilities, and equipment distribution areas — this trunk arrives factory-terminated and tested, so you skip the field-termination labor, the cleave-and-crimp variability, and the re-test cycles that drive up installation cost and project risk.
Pre-terminated infrastructure is the right call when you're provisioning structured cabling at scale. Field termination on 144 fibers, per run, across dozens of pathways, introduces error rates and schedule risk that simply don't exist when the cable ships as a finished, tested assembly. The FY9AP77A005M050 is built to eliminate that variable from your deployment.
Key Features
- 144 Single-Mode Fibers: 144 discrete fibers in a single sheath means a single trunk pull covers the full port density of a high-density patch panel or switch shelf without stacking multiple smaller trunks. For high-density fiber optic backbone runs, this is the format that keeps pathway fill rates manageable.
- 50M (164.1 ft) Factory Length: The 50-meter run length is sized for mid-range data center spine connections — MDA-to-HDA, main cross-connect to zone distribution, or inter-row backbone — where shorter trunks fall short and longer ones introduce unnecessary slack management overhead. You pull the exact length you need without field-cutting.
- ST Connector Termination: ST connectors are specified here, making this trunk compatible with legacy ST-panel infrastructure still present in many telecommunications rooms and enterprise equipment rooms. If your existing panels are ST-based, this trunk drops in without adapter plates or hybrid cords.
- QuickNet HD Flex Sub-Brand: The QuickNet HD Flex platform is Panduit's pre-terminated system architecture built around plug-and-play deployment. Trunks ship tested and labeled, so commissioning is a plug-in operation rather than a termination project. This is a real schedule compressor on large-scale rollouts.
- Single-Mode Fiber Construction: Single-mode glass supports longer distances and higher bandwidth than multimode — the correct choice for backbone runs that need to scale beyond OM4/OM5 distance limits, or where future coherent optics (100G, 400G, 800G) will be installed. You won't be re-pulling fiber when you upgrade transceiver generations.
- Pre-Terminated and Factory-Tested Assembly: Every connector is terminated and tested at the factory before shipment. That means insertion loss and return loss are verified before the cable leaves the building — no field testing surprises, no rework loops, and a documented performance baseline for your as-built records.
- Designed for Rapid Infrastructure Deployment: The explicit application scope — data centers, telecom rooms, entrance facilities, and equipment distribution areas — reflects a trunk built for structured cabling backbone work, not patching or horizontal runs. If you're pulling backbone between distribution frames, this is the appropriate product class.
Integration & Compatibility
The FY9AP77A005M050 integrates into any structured cabling infrastructure built around ST-interface panels and enclosures. It is compatible with Panduit's QuickNet HD Flex enclosure ecosystem and with third-party ST patch panels from other manufacturers where the connector interface matches. Single-mode construction makes it compatible with OS1 and OS2 applications and with the SFP/SFP+ transceivers used in enterprise and carrier switching platforms that specify single-mode ports.
For deployments where the far end terminates in a different connector format, field-installable or pre-terminated hybrid trunks or coupler-based adapters will be required — the FY9AP77A005M050 ships ST-to-ST. Verify both ends of your planned pathway before ordering. For complete network switching infrastructure provisioning, pair this trunk with compatible patch panels and enclosures rated for 144-fiber density.
Frequently Asked Questions
Q: What is the fiber count and type on the FY9AP77A005M050?
A: The FY9AP77A005M050 carries 144 single-mode fibers in a pre-terminated trunk assembly. Single-mode construction supports longer backbone distances and higher bandwidth scalability compared to multimode alternatives.
Q: What is the exact length of the FY9AP77A005M050?
A: The trunk is 50 meters (164.1 feet) in overall length. This is a fixed factory length — it cannot be field-shortened without losing the factory-terminated end.
Q: What connector type is used on the FY9AP77A005M050?
A: The FY9AP77A005M050 uses ST connectors. It is designed for environments with ST-interface patch panels or enclosures. If your infrastructure uses LC, SC, or MPO interfaces, a different trunk or adapter solution will be required.
Q: What applications is the FY9AP77A005M050 designed for?
A: According to Panduit, this trunk is intended for data centers, telecommunications rooms, entrance facilities, and equipment distribution areas requiring pre-terminated fiber infrastructure for rapid deployment. It is a backbone-class product, not a horizontal or patching solution.
Q: Is the FY9AP77A005M050 part of the QuickNet HD Flex system?
A: Yes. The FY9AP77A005M050 is part of Panduit's QuickNet HD Flex pre-terminated cabling platform, which is designed for plug-and-play structured cabling deployment with factory-tested assemblies.
Q: Does the FY9AP77A005M050 require field termination?
A: No. This is a factory pre-terminated assembly. Both ends arrive terminated and tested. No field termination tools, polishing, or post-install insertion loss testing are required on the connector ends themselves — you verify end-to-end after installation, but the terminations are complete from the factory.
The FY9AP77A005M050 is the trunk I'd specify when someone hands me a 144-port panel and a 50-meter backbone run between distribution frames in a data center or telecom room. The ST termination is the key decision point — this product exists specifically for facilities still running ST-interface panels, and trying to adapt it to LC or MPO infrastructure adds a connection point that doesn't belong in a backbone pathway.
Technical Highlights:
- 144-Fiber Density: A single 50-meter pull covers a full high-density panel's port count. Compare that to running three or four smaller trunks through the same conduit fill — 144F in one sheath is a real pathway efficiency win on constrained builds.
- Single-Mode Glass: OS1/OS2 single-mode means this trunk is compatible with 10G, 40G, 100G, and emerging 400G+ optics without a re-pull. If your client is running 10G today and planning a 100G spine upgrade in three years, single-mode is the correct call now.
- Factory Pre-Terminated: At 144 fibers, field termination is not just slower — it's a quality risk. Factory termination with documented test results gives you a verified baseline and eliminates the variability that shows up on large-fiber-count field jobs.
Deployment Considerations:
- The 50-meter fixed length means you need to plan pathway routing carefully before ordering. Measure twice — there's no field-shortening this without losing a factory-terminated end, and splicing adds a connection point that degrades the insertion loss budget.
- ST connectors are the limiting factor here. If even one end of this run terminates into an LC or MPO panel, you'll need a coupler or hybrid cord, which adds insertion loss. Confirm both panel interfaces before the purchase order goes out.
This trunk is the right specification for a telecommunications room backbone pull where the existing panel infrastructure is ST-based and the run falls in the 40–55 meter range — long enough that multimode would require careful distance budgeting, but well within single-mode OS2 reach at any practical data rate.
