Panduit FZUYBXRNNONM050 QuickNet™ OM4 24-Fiber Pre-Terminated Assembly
The Panduit FZUYBXRNNONM050 is a factory-terminated 24-fiber OM4 multimode trunk assembly designed for rapid deployment in data centers, telecommunications rooms, and high-density network environments requiring 40/100GBASE-SR4 support. This 50-meter (164-foot) QuickNet™ assembly delivers plug-and-play fiber infrastructure with front-access connectors and integrated tethering, eliminating field termination labor and the performance variability that comes with on-site splicing. Built to B2CA flame-retardant specifications for European building code compliance, this trunk addresses the dual challenge of accelerated deployment timelines and strict safety requirements in modern structured cabling projects. For integrators managing tight installation windows or deploying in occupied spaces where hot-work restrictions apply, pre-terminated assemblies like this shift termination QA to the factory floor and compress installation time from hours to minutes per run.
Key Features
- 24-fiber OM4 50/125µm multimode construction supporting 40/100 Gigabit Ethernet applications up to 150 meters (OM4 spec) and 10GBASE-SR up to 550 meters
- 50-meter overall length (164.1 feet) factory-terminated and tested, eliminating field splicing and the risk of contamination or improper polish
- B2CA flame rating per EN 50575 for compliance with European Construction Products Regulation (CPR) and Euroclass fire performance requirements
- QuickNet™ front-access design with tethered deployment aid for clean cable management and controlled slack storage in high-density fiber enclosures
- Red jacket color coding for instant OM4 identification per TIA-598-D fiber color standards
- Factory testing and certification to TIA-568.3-D, ISO/IEC 11801, and ANSI/TIA-942-B data center standards with included test reports
- Pre-terminated connectors (connector type determined by model variant) with low insertion loss and optimized return loss for multi-mode laser transmission
- Integrated pull eyes and breakout boots for strain relief and bend-radius protection during installation through cable trays and tight pathways
OM4 fiber delivers 50/125-micron core/cladding geometry optimized for 850nm VCSEL (Vertical Cavity Surface Emitting Laser) transmission, the dominant light source in modern 10/40/100G short-reach applications. Compared to OM3, OM4's lower modal dispersion extends effective bandwidth from 2000 MHz·km to 4700 MHz·km at 850nm, which translates directly to longer reach at higher data rates: 100GBASE-SR4 reaches 150 meters on OM4 versus 100 meters on OM3, a critical difference in large data centers where rack-to-core distances frequently exceed 100 meters. The 24-fiber count in this assembly supports twelve duplex channels, enough for a fully redundant 40G/100G uplink pair with room for future expansion or breakout to 10G connections. Factory termination means every connector endface has been inspected under magnification, cleaned to IEC 61300-3-35 standards, and insertion-loss tested; field terminations, even with qualified technicians, introduce variables (epoxy cure time, polish pressure, ambient contamination) that factory processes eliminate. The B2CA flame rating uses halogen-free, low-smoke compounds that self-extinguish and produce minimal toxic gas under fire conditions—mandatory in European installations and increasingly specified in U.S. projects (hospitals, schools, high-rises) where life-safety codes reference NFPA 262 or equivalent plenum/riser performance.
This assembly integrates into Panduit's QuickNet ecosystem, which uses a front-access architecture: connectors mount on the front panel of fiber enclosures while the trunk cable routes through the rear, keeping all connection activity in the hot aisle and all cable management in the cold aisle. The included tether is a deployment aid—after pulling the trunk into position, the tether holds slack in a controlled loop until you're ready to dress the cable into permanent management, preventing kinks and maintaining the 30mm (1.2-inch) bend radius OM4 requires under load. For telecommunications rooms with overhead ladder rack and floor-level enclosures, the 50-meter length is a common vertical + horizontal run distance: 3-meter raised-floor to ceiling (10 feet), 40 meters horizontal tray run, 7 meters of slack and vertical drop into the destination cabinet. Pre-terminated trunks eliminate the need for fusion splicing equipment, splice trays, and the two-hour per-trunk labor cycle typical of field splicing, compressing a four-trunk installation from a full day to under two hours. In retrofit scenarios—adding capacity to a live data center without shutting down adjacent equipment—the lack of heat-generating fusion splicing and the speed of plug-and-play installation minimize risk and downtime.
The assembly ships with test reports documenting insertion loss, return loss, and length per TIA-568.3-D Tier 1 certification (basic transmission), which satisfies the documentation requirements of ANSI/TIA-942-B (data center infrastructure standard) and ISO/IEC 11801 (generic cabling for customer premises). These reports are serialized to the specific trunk you receive, not generic spec-sheet values, giving you auditable proof of performance for closeout documentation or future troubleshooting. The red jacket is TIA-598-D standard for OM4 identification, ensuring that five years from now, when someone opens the cabinet, they can immediately distinguish OM4 trunks from OM3 (aqua) or single-mode (yellow) without tracing or labeling. Panduit's factory-terminated assemblies use connectors rated for 500+ mating cycles, far exceeding the <50 cycles typical in fixed infrastructure, which means you can relocate or reconfigure this trunk across multiple projects without degrading performance. For integrators bidding on projects with CPR compliance requirements (any commercial building work in the EU, UK, or jurisdictions that reference EN 50575), the B2CA rating is the minimum acceptable class for fixed installation in escape routes and general building areas; non-compliant cable is illegal to install and can void building occupancy permits. This assembly turns a complex compliance requirement into a line-item spec match.
