Panduit FZ2RLU1U1NNM4.5 OM4 Duplex LC Uniboot Fiber Patch Cord, 4.5m LSZH
Overview
The Panduit FZ2RLU1U1NNM4.5 is a 2-fiber OM4 duplex patch cord built for high-density structured cabling environments where space, signal integrity, and fire code compliance all matter at once. It ships in a 4.5-meter length with a slim 2.0mm outer jacket, LC Uniboot connectors on both ends, and an LSZH (Low Smoke Zero Halogen) jacket — a combination that addresses the physical and regulatory demands of enterprise data centers, plenum risers, and industrial network closets in a single SKU.

Key Features
- OM4 Multimode Fiber: OM4 glass supports 10GbE to 400m and 40/100GbE to 150m — meaningful headroom if you're cabling a spine-leaf fabric today and expect to push higher line rates within the next refresh cycle. You won't need to re-pull glass just because the optics change.
- Ultra-Low Insertion Loss: Panduit specifies ultra-low insertion loss on this cord, which matters when you're cascading multiple patch points through high-density cassette systems. Every dB of connector loss reduces your available link budget; ultra-low-loss connectors give you more margin to work with across long multi-segment paths.
- LC Uniboot Connector: The pull-boot LC Uniboot design combines both fiber strands into a single connector body with a reversible polarity mechanism. In practice, this means one hand instead of two during patching, roughly half the connector footprint at the panel face, and the ability to correct A-B polarity on the fly without swapping cords — a real time saver on dense 1U panels where individual connector access is tight.
- 2.0mm Slim Jacket Diameter: The 2mm outer diameter keeps bend radius tight and allows significantly more cables to route through cable management arms, trays, and raceway cutouts without the airflow restriction you get from 3mm duplex cords. In a fully loaded 42U cabinet, the difference between 2mm and 3mm cords across 48 ports adds up to real airflow.
- LSZH Jacket: Low Smoke Zero Halogen construction is required by code in enclosed spaces — transit tunnels, high-rise risers, plenum zones, and many European and APAC data centers by default. In a fire event, LSZH jackets produce significantly less toxic smoke than PVC, which is the controlling factor in evacuation time and equipment survival in enclosed plant rooms.
- 4.5m Patch Length: 4.5 meters is a practical reach for cross-connects between adjacent cabinets or for running from a top-of-rack switch to a mid-row patch panel without excess slack piling up. It sits between the typical 3m intra-rack cord and the 7m inter-row reach — right-sized for most cabinet-to-cabinet horizontal runs.
- A-B Polarity Labeled: The cord is supplied with A-B polarity designation, which aligns with TIA-568 Method B (the dominant standard in US enterprise cabling). This eliminates guesswork during commissioning and simplifies documentation for future moves, adds, and changes.
Integration and Compatibility
The FZ2RLU1U1NNM4.5 terminates with LC Uniboot connectors, making it directly compatible with any LC-port SFP, SFP+, QSFP breakout, or cassette port — including Panduit's own fiber optic patch panels and cassette systems. OM4 glass is backward-compatible with OM3 equipment; you'll simply operate within OM3 distance limits when mixed. Pair this cord with an appropriate OM4-rated SFP+ or SFP28 transceiver to maximize available link budget. The LSZH jacket satisfies IEC 60332, EN 50267, and EN 50575 Eca flame-spread requirements — verify your local jurisdiction's specific code reference before specifying for a plenum or riser application. For full structured cabling planning, review channel insertion loss budgets when combining this cord with trunk assemblies and inline adapters.
Frequently Asked Questions
Q: What fiber type does the FZ2RLU1U1NNM4.5 use, and what speeds does it support?
A: This cord uses OM4 multimode fiber, which supports 10 Gigabit Ethernet to 400 meters and 40/100 Gigabit Ethernet to 150 meters per IEEE 802.3 standards. It is backward-compatible with OM3 equipment but will be limited to OM3 distances in that configuration.
Q: What does LC Uniboot mean, and how does it differ from a standard duplex LC?
A: LC Uniboot combines both fiber strands into a single connector body rather than the two separate connector bodies used on standard duplex LC cords. This halves the panel footprint, simplifies one-handed patching in tight spaces, and includes a reversible polarity mechanism so you can correct A-B orientation without swapping cables.
Q: Why specify an LSZH jacket instead of PVC for this application?
A: LSZH (Low Smoke Zero Halogen) jackets are required by building code in many enclosed or high-occupancy spaces — data center risers, transit facilities, European and APAC installations, and plenum zones. In a fire event, LSZH produces significantly less toxic smoke and no halogen acid gases compared to PVC, which is the critical factor for personnel safety and equipment survival in enclosed environments.
Q: Is the FZ2RLU1U1NNM4.5 available in other lengths?
A: The FZ2RLU1U1NNM4.5 is specified at 4.5 meters. Panduit manufactures this cord family in multiple lengths; consult the Panduit fiber patch cord series for the SKU corresponding to your required reach.
Q: What is the minimum order quantity for this SKU?
A: This SKU carries a minimum order quantity of 10 units (MOQ10), as indicated in the product designation. Plan your cable schedule accordingly when specifying for phased rollouts.
Q: Is this cord compatible with OM3 transceivers and panels?
A: Yes. OM4 fiber is backward-compatible with OM3-rated equipment. When mixed with OM3 components, the link distance will be governed by the OM3 specification rather than the OM4 specification.
The detail I keep coming back to on the FZ2RLU1U1NNM4.5 is the Uniboot connector combined with the 2.0mm slim jacket — that pairing is specifically engineered for high-density LC panels where airflow and patching ergonomics are both real constraints, not afterthoughts. In a 1U 48-port cassette environment, switching from standard duplex LC to Uniboot effectively halves the connector footprint at the panel face, which translates directly to easier fiber management and better visibility of port IDs during MACs.
Technical Highlights:
- OM4 Glass: Supports 100GbE to 150 meters — meaningful if you're building spine-leaf at 25G or 100G today and need runway for the next line-rate upgrade without re-pulling glass.
- Ultra-Low Insertion Loss: In cascaded patch systems (cord → cassette → trunk → cassette → cord), connector loss accumulates quickly. Ultra-low insertion loss on each mated pair gives you more link budget margin, which becomes the difference between a clean channel and an intermittent error floor at 100G.
- LSZH Jacket: Code-required in enclosed risers and international installations; this isn't an optional upgrade — if your facility requires LSZH, a PVC cord is a non-starter regardless of optical performance.
Deployment Considerations:
- The MOQ10 on this SKU is worth flagging early in your cable schedule — if you're specifying a mix of lengths across a project, confirm your quantities per length before purchasing to avoid short-shipped phase completions.
- Uniboot polarity reversal is field-serviceable, but document your polarity scheme at installation. A-B labeling is present on this cord; verify it aligns with your TIA-568 Method B or method A/C plan before commissioning to avoid having to reverse connectors at the cassette after the fact.
This cord is the right specification for a code-compliant, high-density LC fiber cross-connect in a multi-tenant data center, enterprise MDA/IDA environment, or any enclosed facility where LSZH is mandated and patching ergonomics at scale genuinely matter to the operations team.
