Panduit FRZUP77Y002F039 39ft OM4 Pre-Terminated Fiber Cable Assembly
Overview
The Panduit FRZUP77Y002F039 is a 39-foot OM4 multimode fiber cable assembly built for enterprise network interconnects where field termination introduces risk you'd rather not take. Pre-terminated at the factory, it arrives ready to deploy — no polishing, no fusion splicing, no guessing about connector geometry. For network closets and data center rows where rack-to-rack distances fall in the 30–40 foot range, this assembly drops right into the gap without forcing a longer cable into an awkward coil.

Key Features
- 39 ft factory-terminated assembly: A 39-foot run covers the overwhelming majority of same-row and cross-row rack interconnects without excess slack to manage. Factory termination removes connector-loss variability — the leading cause of marginal optical links in field-installed cabling.
- OM4 multimode fiber: OM4 is the backbone-grade choice for multimode fiber deployments running 10GbE, 25GbE, or 40GbE at short-to-medium distances. It delivers higher bandwidth headroom than OM3, which matters when you're building infrastructure that needs to survive the next switch refresh without a re-pull.
- Pre-terminated optical assembly: Factory-built connectors are polished and tested under controlled conditions. You get a cable that's ready to characterize with an OLTS on arrival rather than one that needs remediation before it passes insertion loss. Installation time drops, and the first-pass yield on your fiber acceptance testing goes up.
- Designed for enterprise network interconnects: This is production-grade cabling built for switch-to-switch and aggregation-layer links, not a grey-market commodity patch cord. The assembly is suited to structured fiber deployments where documentation, serviceability, and cable management discipline matter.
- Supports structured cabling discipline: A factory assembly with a defined length enforces clean routing. It discourages the improvised loops and over-long runs that create airflow and cooling problems in high-density cabinets.
- Reduces deployment risk: Pre-terminated assemblies from a production cabling manufacturer eliminate the skill dependency of field termination. Any qualified network technician can install it without specialized splicing equipment on site.
Integration & Compatibility
OM4 multimode fiber is compatible with LC duplex transceivers running at 10GbE (up to 400m), 25GbE, and 40GbE short-reach optics. Pair this assembly with compatible fiber optic transceivers and OM4-rated patch panels or cassettes to complete the link. For aggregation runs requiring higher fiber counts or longer reach, see trunk cable assemblies in the same Panduit fiber family. This cable is not suited to single-mode (OS2) applications — verify your switch ports are multimode-compatible before ordering.
Frequently Asked Questions
Q: What fiber standard does the FRZUP77Y002F039 use?
A: It uses OM4 multimode fiber, suitable for high-bandwidth short-reach applications including 10GbE, 25GbE, and 40GbE links in data centers and network closets.
Q: Is the FRZUP77Y002F039 field-terminable or is it pre-terminated?
A: It is a pre-terminated factory assembly. Connectors are installed and finished at the factory — no field termination is required or intended.
Q: What is the cable length of the FRZUP77Y002F039?
A: The cable is 39 feet (approximately 11.9 meters), designed for shorter rack-to-rack and switch-to-switch interconnects.
Q: Can I use this cable with single-mode (OS2) equipment?
A: No. This is an OM4 multimode assembly. Single-mode transceivers require OS2 cable. Verify your switch ports are multimode-compatible before ordering.
Q: What applications is this assembly best suited for?
A: Switch-to-switch links in network closets, rack-to-rack interconnects in data centers, and structured fiber deployments requiring pre-terminated short-reach multimode runs.
The FRZUP77Y002F039 earns its place in production environments specifically because of the 39-foot factory-terminated OM4 build. In my experience, short-reach multimode runs are where field termination errors hurt the most — the loss budget is tight, the connectors are right at the IDF, and a bad cleave on a 39-foot cord is just as damaging as one on a 300-foot trunk. Getting a factory-polished assembly here is not over-engineering; it's the correct call.
Technical Highlights:
- OM4 multimode fiber: Higher bandwidth ceiling than OM3 — this is the correct grade for 10GbE and 25GbE short-reach optics, and it gives you headroom for a future transceiver swap without a cable re-pull.
- 39ft pre-terminated length: Covers same-cabinet and adjacent-rack interconnects cleanly. Long enough for most IDF cross-connects, short enough to avoid the slack management problems that come with 50- or 75-foot cords bundled into a tight cabinet.
- Factory-terminated assembly: Removes the skill and equipment dependency of field splicing. Any tech can seat the connectors and run an OLTS test at installation — no fusion splicer, no termination kit on site.
Deployment Considerations:
- Confirm your switch ports and patch panels are OM4-rated multimode before ordering — this assembly will not perform correctly on single-mode (OS2) ports regardless of physical connector compatibility.
- At 39 feet, routing path matters: measure the actual cable tray run, not just the linear rack distance. An indirect route through a cable tray can easily add 8–12 feet and turn a 39-foot cord into a short one.
This assembly is the right pick for aggregation-layer switch interconnects in a structured IDF or MDF environment where you want a clean, serviceable, documented fiber plant — not a field-terminated patchwork that varies technician to technician.
