Panduit FOBKF48YM1 QuickNet 48-Fiber Singlemode Breakout Kit

The Panduit FOBKF48YM1 QuickNet fiber breakout assembly transitions a 48-fiber trunk cable to individual connectorized fibers in high-density datacenter, telecom CO, and enterprise network installations. This 1-meter singlemode breakout is engineered for patch panel feed applications where trunk cables enter cabinets or zone distribution boxes and must fan out to individual port connections. The flat breakout configuration maintains organized fiber routing in tight spaces while the yellow jacketing provides instant visual identification of singlemode infrastructure per TIA-598-C color coding standards.

Key Features

• 48-fiber singlemode breakout handles backbone-to-distribution transitions in high-port-count applications
• 1-meter length sized for cabinet and rack patch panel connections without excess slack
• Flat breakout design improves cable management and airflow compared to round fanout configurations
• Yellow jacketing meets TIA-598-C singlemode fiber color identification standards
• QuickNet pre-terminated construction eliminates field splicing and reduces installation time by 70% versus fusion-splice deployments
• Factory-tested continuity and insertion loss ensures reliable performance out of the box

The flat breakout geometry of the FOBKF48YM1 addresses a critical pain point in high-density fiber installations: maintaining separation and bend-radius compliance when fanning out from trunk to individual fibers. Unlike round breakout boots that create a bulky transition point, the flat design spreads the 48 individual fibers across a wider plane, reducing congestion at the trunk termination and improving accessibility for moves/adds/changes. Each leg maintains the 2mm tight-buffered construction required for direct termination to LC, SC, or ST connectors (connector type depends on trunk cable specification). The QuickNet platform's factory termination means every fiber arrives with pre-polished end faces and verified optical performance—eliminating the variability, equipment cost, and skill requirements of field fusion splicing. For integrators managing large fiber counts in equipment rooms or central offices, this translates to faster project completion and reduced labor costs, particularly on projects with dozens of trunk cables requiring breakout.

This 1-meter length is optimized for the typical distance between a trunk cable entry point and the patch panel or fiber distribution unit it feeds. In a standard 19-inch rack installation, 1 meter provides sufficient reach from a vertical cable manager or overhead cable tray to the panel mounting position, with minimal excess that would otherwise require coiling and create clutter. The singlemode specification supports the 9/125µm fiber core used in campus backbone runs, inter-building links, and long-haul telecom applications where link distances exceed the 300-meter ceiling of multimode OM3/OM4 fiber. Yellow jacketing is the mandated color for singlemode per TIA-598-C, allowing instant visual differentiation from orange (OM1/OM2), aqua (OM3/OM4), or lime (OM5) multimode infrastructure during troubleshooting and adds. In datacenter environments running 100G/400G Ethernet or Fibre Channel links, the 48-fiber capacity of this breakout kit supports twelve duplex connections per trunk—ideal for spine-leaf architectures or storage area network aggregation points.

Panduit's QuickNet pre-terminated fiber platform is factory-assembled in a controlled clean-room environment with automated polishing and 100% end-face inspection, delivering insertion loss performance that consistently beats field-terminated alternatives. The FOBKF48YM1 is compatible with Panduit's full range of QuickNet trunk cables, cassettes, and enclosures, providing a complete plug-and-play fiber infrastructure solution that reduces project risk and commissioning time on enterprise network builds, colocation facility deployments, and carrier-grade installations.
