Panduit FYZUP77Y005F028 QuickNet HD Flex 24-Fiber Single-Mode Pre-Terminated Trunk Cable
Overview
The Panduit FYZUP77Y005F028 is a 24-fiber single-mode pre-terminated fiber trunk assembly from the Panduit QuickNet HD Flex line, cut to a 28-foot (8.5m) length and factory-terminated for pull-and-plug deployment. This is the product to reach for when your structured cabling timeline cannot absorb field termination labor — data centers, telecom rooms, entrance facilities, and equipment distribution areas where a verified low-insertion-loss connection matters more than field flexibility. Pre-terminated trunks like this one compress a multi-hour field splice into a sub-minute connection event; the tradeoff is that the fixed 28ft run length must match your planned route before you order.
Key Features
- 24-Fiber Single-Mode Core: Twenty-four SM fibers in a single trunk handle high-density backbone runs between fiber patch panels and active equipment. At 24 fibers per assembly, you consolidate what would otherwise require multiple smaller trunks, reducing the number of connection points and associated insertion loss events in the link.
- Factory Pre-Terminated: Both ends are terminated and tested at the factory before shipment. Field termination introduces variables — tool condition, technician skill, contamination. Factory terminations eliminate those variables and arrive with verified performance, which matters on high-speed links where marginal insertion loss compounds across a backbone.
- 28ft / 8.5m Fixed Length: This specific assembly spans 28 feet (8.5 meters) — sized for within-row or cross-row data center runs, short inter-rack hops, or telecom room horizontal connects. Measure your exact routing path including any overhead tray turns before committing; factory-terminated trunks are not field-adjustable in length.
- QuickNet HD Flex Sub-Brand: The HD Flex designation indicates this trunk is part of Panduit's high-density flexible infrastructure system, designed to pair with QuickNet HD Flex modules and cassettes. Mixing QuickNet HD Flex trunks with incompatible modules voids the mated-system performance guarantee — confirm your cassette/panel part numbers match the HD Flex series before ordering.
- Rapid Deployment for Structured Cabling Projects: Pre-terminated fiber trunk assemblies are the standard approach in modern data center builds where installation windows are tight and post-installation testing documentation is required. Each factory assembly ships with traceable test data, simplifying the commissioning sign-off process.
- Broad Application Coverage: Rated for data centers, telecommunications rooms, entrance facilities, and equipment distribution areas — the standard structured cabling environments defined in TIA-942 and BICSI guidelines. Suitable wherever a fixed-length, high-fiber-count pre-terminated run fits the topology.
Integration and Compatibility
The FYZUP77Y005F028 is engineered for use within the Panduit QuickNet HD Flex ecosystem. It is intended to mate with compatible HD Flex cassettes and panels; confirm the connector interface (F1MBO designation in the part number indicates the specific connector type on each end) matches your receiving hardware. Single-mode fiber requires SM-compatible transceivers and active equipment — do not install into a multimode-only link budget.
Frequently Asked Questions
Q: What environments is the FYZUP77Y005F028 designed for?
A: Data centers, telecommunications rooms, entrance facilities, and equipment distribution areas requiring pre-terminated fiber infrastructure for rapid deployment.
Q: What is the exact length of the FYZUP77Y005F028?
A: The assembly is 28.0 feet (8.5 meters). This is a fixed factory-terminated length and cannot be adjusted in the field.
Q: How many fibers does the FYZUP77Y005F028 carry?
A: Twenty-four (24) fibers in a single-mode configuration.
Q: Can the FYZUP77Y005F028 be used with multimode equipment?
A: No. This is a single-mode assembly. It must be used with single-mode transceivers and single-mode compatible active equipment throughout the link.
Q: Does the FYZUP77Y005F028 require field termination?
A: No. Both ends are factory pre-terminated and tested before shipment. No field termination tooling or splicing is required for installation.
Q: What system does the FYZUP77Y005F028 belong to?
A: It is part of the Panduit QuickNet HD Flex pre-terminated fiber infrastructure system. It is designed to mate with compatible QuickNet HD Flex cassettes and panels.
The FYZUP77Y005F028 is exactly the kind of assembly that saves a data center build schedule — factory-terminated, 24-fiber single-mode at a fixed 28ft (8.5m), ready to pull and plug without touching a splice tray or polishing puck on site. When I spec pre-terminated trunks for a structured cabling rollout, the fixed length is the one variable that bites integrators who measure incorrectly; on this assembly, 28 feet is what ships, full stop.
Technical Highlights:
- 24-Fiber Count: Consolidates high-density backbone connectivity into a single pull — fewer assemblies to manage, fewer connection interfaces to test, and simpler documentation at commissioning.
- 28ft / 8.5m Factory Length: Sized for within-row data center hops and short inter-rack runs. At 8.5 meters you have enough slack for overhead tray routing with a gentle bend radius, but not so much excess that cable management becomes an issue in a tight cabinet.
- QuickNet HD Flex System Membership: Mating within the HD Flex ecosystem means the cassette-to-trunk interface is controlled for insertion loss at the system level — a meaningful advantage over mixing trunk brands when you're building a link budget for 400G or higher.
Deployment Considerations:
- Measure routed cable path — not straight-line distance — before ordering. Tray turns, ladder rack drops, and cabinet entry loops all consume length. A 28ft trunk that is 2 feet short requires a full replacement assembly, not a field splice.
- Single-mode fiber mandates SM-rated transceivers throughout the link. If the receiving switch or active equipment is multimode-only, this assembly will not function correctly regardless of connector fit.
This trunk is the right call for greenfield data center builds or telecom room refreshes where the routing is planned, the cassette hardware is confirmed HD Flex-compatible, and the project timeline cannot absorb field termination labor on a 24-fiber run.
