Panduit FHDBRKOUT28 Fiber Trunk Breakout Kit 16-28mm

Panduit FHDBRKOUT28 High Fiber Count Cable Breakout Kit

The Panduit FHDBRKOUT28 addresses a core challenge in high-density fiber deployments: transitioning trunk cables carrying 48, 96, 144, or more fibers into manageable groupings for termination and patching. In datacenter spine-leaf architectures, campus backbone runs, and carrier hotel cross-connects, you need clean breakout points that prevent kinking, maintain minimum bend radius, and provide future access for MAC work. This kit splits one large-diameter trunk (16–28mm outer diameter, roughly 0.63–1.10 inches) into six organized sub-groups using expandable sleeve assemblies that snap directly into the metal housing. Each sleeve cinches around a fiber bundle, securing it against strain while keeping individual fibers accessible. The metal construction provides crush resistance in congested ladder racks and cable trays where loose breakouts risk damage during subsequent cable pulls.

Key Features

• Splits single trunk cable into six manageable fiber groupings for termination or patching
• Accommodates 16–28mm (0.63–1.10 in) outer diameter trunk cables — fits most 48F to 144F assemblies
• Six expandable sleeve assemblies snap into metal housing for tool-free installation
• Metal construction resists crushing in dense ladder rack and cable tray environments
• Black finish matches standard rackmount and cabinet aesthetics
• RoHS compliant for projects with environmental procurement requirements

High fiber count cables — typically 72F, 96F, 144F, or 288F trunk assemblies — arrive at patch panels, ODF frames, or MPO cassette shelves as single large-diameter bundles. Direct termination without intermediate breakout creates a tangled mass at the cabinet entry point, makes individual fiber identification nearly impossible during troubleshooting, and risks exceeding bend radius limits when routing to distributed termination points. The FHDBRKOUT28 solves this by fanning the trunk into six sub-bundles at a controlled transition point. Each expandable sleeve cinches around a logical fiber grouping (for example, splitting a 144F trunk into six 24F groups), holding that sub-bundle securely while you route it to its designated termination row. The snap-in sleeve design means no heat shrink, no cable ties that dig into jacket material, and no loose furcation tubing that slides out of position during cable pulls. You can install the kit at the cabinet entry point — securing it to vertical cable management or directly to the rack rail — then route each sub-bundle independently to its MTP adapter panel, LC duplex termination block, or splice tray.

In spine-leaf datacenter fabrics, you're often running 144F OS2 trunks from spine switches on one row to leaf switches distributed across the room. Breaking out at the spine cabinet lets you dress each 24F group to its corresponding leaf without a chaotic bundle crossing overhead trays. In campus backbone deployments, a 96F trunk entering a building MDF might split into six 16F groups serving different IDFs, equipment rooms, or tenant spaces. The FHDBRKOUT28 provides that organized transition point, preventing the "rat's nest" effect that develops when loose breakouts shift during subsequent MAC work. The metal housing mounts via integrated holes or slots (verify mounting pattern against your cable manager or rack rail), and the black finish matches Panduit's NetRunner and PatchRunner cable management systems. The 16–28mm diameter range covers most outdoor-rated loose tube cables, indoor tight-buffered distribution cables, and MTP trunk assemblies in 2.0mm, 2.4mm, or 3.0mm jacket constructions. If you're installing 12F or 24F cables, this kit is oversized; Panduit's smaller breakout kits (FHDBRKOUT12, FHDBRKOUT16) fit those applications. Conversely, if you're handling 288F or 432F hyperscale trunks with >28mm outer diameter, you'll need custom furcation or larger-capacity breakout enclosures.

RoHS compliance meets procurement requirements for federal, state, and municipal projects that reference environmental standards in bid specs. The kit ships as a single assembly (one kit per package, no multi-packs) with all six sleeve assemblies included. For parallel backbone installations — say, six 144F trunks entering a carrier hotel meet-me room — order six FHDBRKOUT28 units to maintain symmetry and simplify future adds. The breakout point is where you enforce jacket continuity, apply strain relief, and document your trunk-to-distribution mapping. Do it cleanly with metal hardware and snap-in sleeves, or spend the next five years untangling zip-tied furcation tube every time a port gets re-provisioned.
