Mini-Breakout Fiber Optic Cable
Mini-breakout fiber optic cable I-V(ZN)H 12-24 is a compact indoor LSZH cable designed for direct termination, riser routing, backbone links and fiber-to-the-desk installations where space, fire safety and installation speed matter.
This mini breakout construction combines 900 µm tight-buffered fibers, non-metallic strength members and an LSZH outer jacket in one practical indoor cable design. It is well suited for office buildings, campuses, technical rooms, shafts, underfloor pathways and structured cabling projects that need reliable indoor optical distribution without the bulk of larger breakout constructions.
Mini-Breakout Fiber Optic Cable Overview
The main strength of I-V(ZN)H 12-24 Mini-BreakOUT is installation efficiency. Each fiber is individually protected in a 900 µm tight buffer, which allows direct connector fitting and reduces the need for extra fan-out accessories in many indoor terminations. That helps shorten labor time and keeps indoor backbone and horizontal cabling projects cleaner and faster.
The cable structure is also a strong fit for projects where low smoke and halogen-free material is mandatory. In commercial buildings, hospitals, data centers and public facilities, the LSZH jacket supports safer indoor cable routing while keeping the cable compact and flexible enough for shafts, trays and raised-floor pathways.
For buyers comparing indoor cable families, this model sits between lighter simplex/zipcord options and larger breakout constructions. If you need a broader overview of indoor and outdoor cable families, see our fiber optic and data LAN cables category page and our fiber optic cable overview.

- Patch, adapter and trunk cable assemblies
- Data rooms, technical rooms and campus buildings
- Underfloor systems and cable shaft installations
- Projects needing halogen-free, gel-free indoor cable routing
When this cable makes sense
- When you need more fibers than a simplex or duplex construction
- When direct termination is preferred to save field labor
- When installation space is limited but moderate tensile strength is still required
- When indoor fire-performance expectations rule out standard PVC jacket designs
If your project is focused on smaller indoor fiber counts, you can also review our I-V(ZN)H 1x1 SX Zip. For broader indoor mini-breakout alternatives, see the mini breakout cable family page. For FTTD and terminal-side routing, the drop fiber cable category can also be relevant depending on route and connector strategy.

How to Install I-V(ZN)H 12-24 Mini-BreakOUT
-
Check the route before pulling
Confirm whether the cable will run in shafts, trays, underfloor channels or indoor riser paths. Tight spaces are usually where a mini-breakout cable gives the biggest advantage.
-
Select the right fiber count and fiber type
Choose 2 to 24 fibers based on current terminations and future reserve capacity. Match the optical type to the project requirement: OM-series for multimode or G.652-D / G.657.A for single-mode networks.
-
Protect bend radius during installation
Respect the minimum bending radius of 20 x outer diameter and avoid tight corners, aggressive pulling and unsupported drops inside risers or cabinets.
-
Terminate cleanly at the destination point
The 900 µm tight-buffered fibers support direct connector fitting. Use correct preparation tools and keep the indoor termination area clean and organized.
-
Label and test after installation
After routing and termination, identify fibers correctly and verify link performance according to the project test plan before final handover.

FAQ About I-V(ZN)H 12-24 Mini-BreakOUT
It is used for indoor fiber distribution, riser cabling, backbone links, patching and fiber-to-the-desk applications where direct termination and compact routing are required.
Yes. The 900 µm tight-buffered fiber construction supports direct connector assembly, which is one of the key advantages of this cable family.
This model is intended for indoor use. It is commonly installed in shafts, underfloor areas, risers, technical rooms and structured building cabling routes.
The cable can be produced with OM1, OM2, OM3, OM4, G.652-D and G.657A fibers depending on the transmission requirement and installation scenario.
Mini-breakout designs provide higher fiber counts and a more consolidated indoor structure, while simplex or duplex zipcord constructions are more suitable for lower fiber-count indoor links and patching needs.
