Panduit FZ2RPU1ZNONM041 QuickNet™ OM4 LC Uniboot Fiber Trunk Assembly
The Panduit FZ2RPU1ZNONM041 is a 41-meter (134.5 ft) factory-terminated OM4 multimode fiber trunk assembly engineered to eliminate field termination labor and risk in mission-critical datacenter and telecom deployments. This 2-fiber assembly features LC duplex uniboot connectors on both ends, plenum-rated (OFNP) 2mm round cordage, and ships with factory test reports verifying insertion loss and return loss performance. Pre-terminated trunk assemblies like this reduce installation time by 70-80% compared to field splicing or connectorization, while delivering guaranteed performance backed by Panduit's manufacturing quality controls. The LC uniboot form factor saves 50% of the patch-panel port density compared to traditional duplex LC boots, and allows tool-free polarity reversal in seconds—critical for 40GBASE-SR4 and 100GBASE-SR4 parallel optics deployments where A-to-B vs. A-to-A polarity must match transceiver pinouts without re-termination.
Key Features
- OM4 50/125µm multimode fiber — Supports 40GbE up to 150 meters and 100GbE up to 100 meters per IEEE 802.3ba, future-proofing installations for 400G migration via BiDi optics
- LC duplex uniboot connectors — Single-body boot design reduces patch-panel footprint by half, with integrated pull-tab for tool-free polarity flip (A↔B swap) to match transceiver requirements
- Plenum-rated OFNP jacket — Listed for use in air-handling spaces per NEC Article 770, meeting code requirements for above-ceiling and raised-floor pathways without conduit
- Factory-terminated and tested — Every assembly ships with insertion loss and return loss test data traceable to fiber position, eliminating field test equipment requirements and contractor termination variability
- 41-meter engineered length — Pre-cut to common datacenter row-to-MDA or floor-to-floor riser span, reducing waste and coil management compared to arbitrary-length pulls
- 2mm round cordage — Smaller OD than traditional 3mm zip-cord simplifies high-density pathway fill calculations and reduces bend-radius stress in tight cable management
- QuickNet™ platform compatibility — Integrates with Panduit's modular cassette and panel systems for end-to-end polarity management in structured cabling architectures
OM4 fiber is the dominant multimode standard in enterprise datacenters and campus backbones because it extends 40G and 100G reach beyond the 100m limits of OM3, using the same 850nm VCSEL optics that keep transceiver costs low. The 50/125µm core/cladding diameter is optimized for laser-based transmission (vs. LED-driven OM1/OM2), delivering effective modal bandwidth of 4700 MHz·km—enough to support 100GBASE-SR4 at 100 meters or 40GBASE-SR4 at 150 meters per IEEE standards. This 41-meter length fits common use cases: rack-to-rack within a row (20-30m), edge-of-row to middle-of-row aggregation (30-50m), or single-floor riser runs in low-rise facilities. For comparison, OM3 fiber at this distance would handle 40G comfortably but limits future 100G upgrades to ~70m, forcing a forklift to OM4 or single-mode during refresh cycles. The aqua-colored jacket follows TIA-598 color coding for instant identification during moves/adds/changes. Panduit's factory termination process uses automated polishing and inspection (interferometric and visual), consistently achieving <0.15 dB insertion loss and >20 dB return loss—performance levels difficult to replicate in the field even with skilled techs and premium consumables. Each connector is individually tested and serialized, with results included in the shipping documentation. This traceability matters during acceptance testing and troubleshooting: if a link fails certification, the test report narrows fault isolation to a specific connector position rather than requiring re-termination of the entire trunk.
The LC uniboot connector is a space-efficiency breakthrough for high-density environments. Traditional duplex LC connectors use side-by-side boots occupying two rows in a panel; uniboot stacks the transmit and receive fibers in a single compact housing, effectively doubling port density in the same 1U panel. The polarity-flip mechanism is a sliding tab inside the boot—push the tab, rotate the connector body 180°, and the A/B fiber positions swap without disconnecting or re-lacing cables. This is essential when deploying parallel optics (QSFP+ SR4, QSFP28 SR4) where transceiver manufacturers use different pinout conventions: some expect straight-through polarity (A-to-A), others expect flipped polarity (A-to-B). Field techs can correct mismatches in under 10 seconds per link without inventory of reverse-polarity adapters or custom cable assemblies. The 2mm round jacket keeps the assembly flexible and easy to dress in vertical cable managers and horizontal bend-radius trays. Round cordage also simplifies conduit fill calculations under NEC Chapter 9 Table 1: a 2mm OD cable has 3.14 mm² cross-section vs. 6mm² for typical 3mm zip-cord, reducing jam ratio in congested pathways and allowing more cables per EMT or innerduct pull. Plenum rating (OFNP per UL 910) authorizes installation in air-return plenums, above drop ceilings, and under raised floors without metal conduit—a significant labor and material savings in retrofit projects where pulling new conduit is cost-prohibitive. The jacket is low-smoke and flame-retardant, meeting NEC Article 770.113(A) requirements for fiber optic cables in ducts, plenums, and other spaces used for environmental air.
This assembly is third-party tested to TIA-568.3-D (commercial building telecommunications cabling for optical fiber), ISO/IEC 11801 (generic cabling for customer premises), and ANSI/TIA-942-B (data center infrastructure standard). Compliance to TIA-942-B Tier III/IV requirements includes documentation of polarity method (typically Method A or Method B in structured deployments), pathway diversity for redundant links, and adherence to the 1.5 dB insertion loss channel budget for OM4 at 40/100G speeds. Panduit provides a 20-year warranty on QuickNet assemblies when installed per manufacturer guidelines, covering both the physical cable and optical performance—far exceeding the typical 1-year contractor warranty on field-terminated links. For integrators bidding datacenter builds or telecom room upgrades, pre-terminated trunks shift risk from field labor to factory quality control, compress installation schedules by eliminating termination and testing steps, and deliver turnkey performance documentation that satisfies engineer signoff without deploying OTDR or tier-2 certification testers on-site.
