Panduit FRZUP77Y002F024 OM4 24-Fiber Plenum Breakout Trunk Assembly

The Panduit FRZUP77Y002F024 is a factory-terminated 24-fiber OM4 interconnect assembly rated for plenum air-handling spaces, with a 24-foot trunk and 60cm breakout legs — engineered for high-density fiber optic cabling in data centers and enterprise backbones where you need maximum fiber counts without field-terminating every strand. If you're pulling cable above a drop ceiling in a code-enforced plenum zone, this assembly eliminates the field-termination risk and the labor cost that comes with it.

Overview

Pre-terminated trunk assemblies like this exist for one reason: consistency. Field terminations introduce variables — cleave quality, epoxy cure time, connector end-face geometry. A factory-terminated breakout ships with every connector already tested against insertion loss and return loss standards. For 24 fibers running simultaneously, that's 24 fewer variables per cable run. The 60cm breakout length provides enough slack to route individual legs to their ports without stressing the fiber, which matters in dense patch environments where bend radius violations silently degrade link margins.

Key Features

• OM4 Multimode Fiber: OM4 supports 40G and 100G Ethernet over longer distances than OM3 — up to 150m at 100G vs. 100m for OM3. If your data center backbone spans more than a single row or two, the extra distance headroom keeps your topology options open without upgrading to single-mode.
• 24-Fiber Count: Twenty-four fibers in a single pre-terminated assembly means you can provision a full MTP/MPO-based infrastructure spine in one pull. For structured cabling installations running parallel to fiber optic assemblies, consolidating to a single trunk run reduces pathway congestion and simplifies future moves/adds/changes.
• Plenum (CMP) Rating: Plenum-rated jacket compounds produce lower smoke and reduced flame spread compared to riser (CMR) cable — required by the NEC in air-handling spaces. Substituting a riser-rated assembly here is a code violation. The FRZUP77Y002F024 is built for the spaces where plenum rating isn't optional.
• 24-Foot Trunk Length: The 24ft run is sized for inter-rack or end-of-row switch-to-distribution runs in standard data center layouts — long enough to reach across a hot/cold aisle, short enough to avoid cable management headaches from excess slack.
• 60cm Breakout Legs: Sixty centimeters of breakout gives individual fiber legs enough length to dress into patch panels or active equipment without sharp bends. In a high-density fiber patch panel environment, this is the spec that separates clean installs from ones that fail bend-radius compliance on the first inspection.
• Factory-Terminated Construction: Pre-terminated assemblies ship ready to install — no field polishing, no epoxy, no cure time. For a 24-fiber count, that's a meaningful labor savings versus field-termination kits, and factory test data travels with the assembly.

Integration and Compatibility

The FRZUP77Y002F024 is designed for integration with Panduit's fiber infrastructure ecosystem — enclosures, cassettes, and patch panels within the structured cabling product line. Verify connector type compatibility with your enclosure and active equipment before ordering; a 24-fiber breakout assembly with mismatched connectors on the equipment end creates a re-termination scenario that erases the labor savings of a pre-terminated solution.

Frequently Asked Questions

Q: What is the plenum rating on the FRZUP77Y002F024, and where is it required?

A: The FRZUP77Y002F024 carries a plenum (CMP) jacket rating, required by the NEC wherever cable runs through air-handling spaces such as above suspended ceilings used as return-air plenums. Riser-rated cable is not an acceptable substitute in these environments.

Q: What fiber type does the FRZUP77Y002F024 use, and what speeds does OM4 support?

A: The assembly uses OM4 multimode fiber, which supports 40GbE up to 150m and 100GbE up to 150m — a meaningful distance advantage over OM3 for longer backbone runs.

Q: How long are the breakout legs on the FRZUP77Y002F024?

A: Breakout legs are 60cm (approximately 24 inches), providing sufficient routing length to dress individual fibers into patch panels or active equipment while maintaining proper bend radius.

Q: Is the FRZUP77Y002F024 factory-tested?

A: Yes, as a factory-terminated assembly, all connectors are tested at the factory against insertion loss and return loss specifications before shipment — eliminating the variability of field termination for all 24 fibers.

Q: What is the trunk length of the FRZUP77Y002F024?

A: The trunk cable is 24 feet (approximately 7.3 meters), sized for inter-rack and end-of-row runs in standard data center layouts.

Marty Allison

The spec that matters most on the FRZUP77Y002F024 is the 60cm breakout length. In a 24-fiber high-density panel, breakout legs that are too short force sharp fiber bends at the panel entry — which is how you get intermittent link errors that don't show up on a quick test but surface under thermal cycling. Sixty centimeters threads the needle between 'enough slack to dress cleanly' and 'so much slack you're coiling fiber behind the panel.'

Technical Highlights:

• OM4 Fiber Grade: Supports 100GbE at distances up to 150m — 50% further than OM3 at the same data rate. If your backbone spans more than a single equipment row, this headroom matters when you eventually upgrade active equipment.
• Plenum (CMP) Jacket: Non-negotiable in air-handling spaces — CMP compounds produce less toxic smoke than CMR in a fire event, which is why the NEC mandates it above plenum ceilings. Don't substitute riser here regardless of what the contractor proposes.
• 24-Fiber Count, Factory-Terminated: Getting 24 consistent, tested terminations from a factory versus field-terminating the same 24 strands is a realistic 3-4 hour labor difference on a single run, plus the elimination of rework on sub-spec connectors.

Deployment Considerations:

• Verify the connector type on the breakout legs matches your patch panel and active equipment ports before the assembly ships — a mismatch on a 24-fiber pre-terminated trunk means you're re-ordering, not re-terminating.
• The 24-foot trunk is a fixed length. Measure your actual inter-rack distance including the overhead routing path before specifying — trunks with excess length are manageable, trunks that run short require a coupler and an additional cord, which introduces another potential loss point.

This assembly is the right call for data center inter-rack backbone runs in plenum ceiling spaces where installation consistency and code compliance are both load-bearing requirements — specifically end-of-row switch-to-distribution connections in 40G/100G spine-leaf architectures.
