Panduit FRZUP77Y002F043 24-Fiber OM4 Pre-Terminated Trunk Cable Assembly

Overview

The Panduit FRZUP77Y002F043 is a 43-foot, 24-fiber OM4 pre-terminated trunk cable assembly designed for high-density structured cabling environments where installation speed and optical performance both matter. Built to ICT POL B alignment with optimized insertion loss (OPT IL), this trunk is engineered for data center interconnects, MDA-to-EDA runs, and enterprise backbone segments where you need repeatable, low-loss fiber connections without the field-termination variability that plagues technician-terminated assemblies. If your project is running 40G or 100G over multimode — OM4 is the baseline specification, and Panduit's pre-tested factory terminations eliminate one of the most common failure points before your team ever touches the cable.

For integrators speccing Panduit structured cabling into data center or IDF/MDF backbone designs, the FRZUP77Y002F043 fits the standard high-density trunk matrix: 24 fibers, factory-tested end-to-end, plug-in-and-go installation.

Key Features

• OM4 Multimode Fiber (24-Fiber Count): OM4 supports 40GBase-SR4 and 100GBase-SR10 at distances up to 150m and 100m respectively — substantially farther than OM3 at the same data rates. With 24 fibers in a single trunk, you're moving 12 duplex channels per pull, which means fewer cable management headaches and faster rack population in high-density zones.
• 43-Foot Trunk Length: Factory-cut at 43FT (approximately 13.1 meters), this length is sized for typical inter-rack or IDF-to-rack runs where a 25FT falls short and a 50FT creates excess slack management problems. Ordering a pre-measured factory assembly means no field cutting, no polishing, and no insertion-loss guesswork.
• ICT POL B Alignment: POL B (Polarity Method B) is a straight-through pinout where fiber positions are maintained end-to-end, making port mapping predictable and simplifying troubleshooting. If your patch panels and cassettes are spec'd to POL B — which is standard in most modern parallel-optics and breakout deployments — this trunk drops in without adapter flipping or rework.
• Optimized Insertion Loss (OPT IL): Factory-specified OPT IL means connectors are tested and selected for below-standard insertion loss, reducing optical power budget consumption per link. This matters on long-haul OM4 runs or cascaded connections where every 0.1dB of loss you save buys margin back into your link budget.
• Pre-Terminated Factory Assembly: Each end is factory-terminated and 100% tested before shipment. For patch panel and backbone infrastructure projects, this eliminates field-termination defects — the single largest source of fiber link failures during commissioning. Pull the trunk, plug into your cassettes or panels, and move on.
• High-Density Backbone Architecture Fit: 24-fiber trunks are the backbone of zone-based cabling architectures. Paired with a compatible Panduit fiber cassette or adapter panel, this assembly feeds 12 duplex LC ports per trunk end — enough for a full 1U cassette slot, keeping your rack U-count efficient and your fiber runs consolidated.

Integration & Compatibility

The FRZUP77Y002F043 is designed to integrate with Panduit's zone cabling ecosystem — specifically with OM4-rated cassette modules and high-density patch panels that accept standard trunk connectors. POL B alignment is compatible with the majority of modern MTP/MPO cassette designs used in parallel-optics architectures. Verify your panel's polarity specification before ordering: POL A and POL C panels require different trunk alignments and cannot be mixed without an additional method-conversion adapter.

OM4 fiber is backward-compatible with OM3 transceivers, though you will operate at OM3 distance limits if you mix fiber grades in a link. For 40G and 100G parallel optics (SR4/SR10 transceiver types), use OM4 end-to-end for full distance performance. Consult your switch or active equipment transceiver specs to confirm the required fiber grade and connector type before finalizing trunk selection.

Frequently Asked Questions

Q: What polarity method does the FRZUP77Y002F043 use?

A: This assembly uses ICT POL B (Polarity Method B), which provides a straight-through fiber mapping from end to end. This is compatible with the majority of modern MTP/MPO cassette modules. Confirm your panel or cassette polarity before installation — mixing POL A and POL B without a conversion adapter will produce crossed connections.

Q: What data rates and distances does OM4 support?

A: OM4 multimode fiber supports 40GBase-SR4 to 150 meters and 100GBase-SR10 to 100 meters. It also supports 10GBase-SR to 550 meters. These distances assume a compliant end-to-end OM4 link with no mixed fiber grades.

Q: Is the FRZUP77Y002F043 factory tested?

A: Yes. As a Panduit pre-terminated trunk assembly, it is factory-terminated and end-to-end tested before shipment. The OPT IL (optimized insertion loss) designation indicates connectors are selected and verified to meet below-standard insertion loss thresholds.

Q: Can I use this trunk with OM3 equipment or panels?

A: OM4 fiber is backward-compatible with OM3 transceivers, but the link will operate at OM3 distance limits, not OM4. For full 40G/100G distance performance, use OM4 fiber and OM4-rated transceivers throughout the entire link.

Q: How many duplex LC ports does a 24-fiber trunk feed?

A: A 24-fiber trunk carries 24 individual fibers, which translates to 12 duplex channels. When terminated into a standard 12-port duplex LC cassette, a single trunk end populates one full cassette — or 1U of panel space, depending on housing density.

James Everett

The FRZUP77Y002F043 is the kind of assembly that pays for itself in labor savings on day one of a structured cabling buildout. Forty-three feet of 24-fiber OM4, factory-terminated to POL B with optimized insertion loss — that combination means you're not standing at a rack splice tray at 11pm wondering why your OTDR is showing 0.6dB on a connector that should be 0.2. The factory test process catches the bad connectors before they ship; your team just pulls, plugs, and moves on.

Technical Highlights:

• 24-Fiber OM4 Count: Moves 12 duplex channels per trunk pull — one assembly populates a full 12-port LC cassette at each end, keeping backbone fiber consolidated and rack U-count efficient in high-density MDA/EDA zones.
• OPT IL Termination Grade: Optimized insertion loss selection tightens your link budget margin on each connector, which matters on cascaded links or any run where you're close to the 40G or 100G power budget ceiling.
• POL B Straight-Through Alignment: Fiber positions are maintained end-to-end, so port 1 at the head end lands on port 1 at the tail. Eliminates the polarity-reversal debugging that eats hours during commissioning.

Deployment Considerations:

• Confirm your cassette or panel polarity before ordering — POL B trunks cannot be mixed with POL A or POL C panels without a method-conversion adapter. This is the most common ordering error on trunk-based cabling projects.
• The 43FT (approximately 13.1m) length is fixed. Measure your longest inter-rack run before speccing quantities — excess slack coiled in a tray is a cable management problem, and you cannot field-shorten a pre-terminated trunk without losing the factory termination warranty.

This assembly is a solid fit for enterprise data center backbone builds and IDF-to-MDA runs where 40G or 100G parallel optics are in play and the project demands repeatable, verifiable fiber performance without field-termination variables.
