Panduit FHDBRKOUT17 High Fiber Count Cable Breakout Kit

High-density fiber trunk cables deliver capacity, but without proper breakout hardware you're left wrestling dozens of individual fibers at every termination point. The Panduit FHDBRKOUT17 solves this by splitting multi-fiber trunk cables into manageable groupings using six expandable sleeve assemblies that snap into a central metal framework. Supports cable outer diameters from 9 to 17 mm (0.35" to 0.67"), covering the majority of 12-fiber through 144-fiber trunk configurations used in commercial telecom closets, datacenter MDA/HDA deployments, and campus backbone runs.

Key Features

Six expandable sleeve assemblies snap into central breakout frame for organized fiber routing

Accommodates cable outer diameters from 9 mm to 17 mm (0.35" to 0.67")

Metal construction provides durable strain relief at trunk-to-distribution transition points

Black finish for professional appearance in open-rack or enclosed cabinet installations

RoHS compliant for projects requiring environmental material compliance documentation

Single-unit package simplifies inventory and eliminates multi-SKU ordering for breakout hardware

Fiber breakout kits address a specific problem in high-count deployments: the transition from a single armored or tight-buffered trunk cable to individually routed distribution fibers. Without a breakout assembly, installers face two bad options—either leave the trunk jacket intact and create a bulky, unmanageable bundle at the patch panel, or strip the jacket entirely and risk damage to individual fibers during handling. The FHDBRKOUT17 provides a third path: the expandable sleeves grip individual fiber subgroups (typically 6- or 12-fiber units) as they exit the trunk, maintaining bend radius protection while allowing each subgroup to route independently to its termination point. The metal frame anchors to the rack or cabinet, transferring pull tension away from the fibers themselves—critical when trunk cables exceed 50 meters or pass through multiple plenum spaces where friction loads accumulate.

This kit fits into the workflow between trunk cable pull and patch panel termination. Once the trunk cable is secured in the telecom room or datacenter row, you mount the breakout frame to the rack or wall, feed the trunk through the central opening, strip back the outer jacket to expose the subgroup bundles, and slide each subgroup into its own expandable sleeve. The sleeves expand to accommodate the buffer tubes or subunit jackets, then contract slightly to provide grip without compression. From there, each subgroup routes to its designated panel—typically with 6 to 12 inches of service loop retained inside the sleeve for future re-termination work. The 9-17 mm diameter range covers standard 12-fiber distribution cables (around 9-11 mm OD) up through 72- to 144-fiber backbone trunks (14-17 mm OD), so the same breakout kit works across mixed fiber counts within a single installation.

The metal construction matters in two scenarios: high-vibration environments (mechanical rooms, rooftop telecom huts where HVAC or generator vibration transfers through the rack) and installations where the breakout point sits more than three meters from the cable entry, requiring the frame to support the weight of slack trunk cable. Panduit's modular sleeve design also simplifies future adds—if you initially populate four of the six sleeves for a 48-fiber trunk, the remaining two sleeves stay in place for a later upgrade to 72- or 96-fiber without requiring a new breakout assembly or re-work of the existing subgroups.
