Indoor Breakout Fiber Optic Cable
Indoor breakout fiber optic cable I-V(ZN)HH NX1 is a tight-buffered cable developed for indoor LAN, vertical riser and general horizontal installations where direct termination, compact construction and LSZH performance matter.
This cable structure uses 2.0 mm breakout sub-units with 900 µm tight buffers and aramid yarn strength members. The result is a practical indoor cable design for inter-building and intra-building voice or data communication, fan-out routing and field termination in controlled indoor environments.

Indoor Breakout Fiber Optic Cable Overview
I-V(ZN)HH NX1 is an all-dielectric indoor breakout cable built for direct fiber termination and organized routing to different locations within the same installation. Each 2.0 mm sub-unit contains a 900 µm tight buffer supported by aramid yarn, while the outer LSZH jacket supports low-smoke and halogen-free indoor use.
Compared with looser indoor cable constructions, this design gives installers a more practical structure for fan-out style routing, structured cabling rooms, equipment links and indoor backbone sections where neat handling and direct connectorization are priorities.
Key construction points
- 2.0 mm breakout sub-units
- 900 µm tight buffer design
- Aramid yarn strength members
- LSZH sub-unit jacket and LSZH outer jacket
- Numbers or colors for identification
- Complete dry, non-metallic cable structure
- Ripcord available under the outer jacket
I-V(ZN)HH NX1 applications
Indoor LAN cabling
Suitable for data network cabling inside buildings where compact routing, direct termination and clean organization are needed.
Vertical riser runs
Designed for indoor vertical riser sections where installers want breakout handling instead of a looser central-tube design.
General horizontal routes
Useful in horizontal indoor pathways, ducts and conduits where low-smoke halogen-free construction is preferred.
Inter-building links
Can be used in controlled pathways for inter-building and intra-building voice or data communication where the installation conditions fit indoor cable selection logic.
FTTx support cabling
Supports indoor FTTx sections and local distribution points that benefit from breakout design and manageable sub-unit routing.
Field termination projects
Well matched to applications where direct connector termination in the field is part of the installation plan.

How to choose the right I-V(ZN)HH NX1 configuration
Selection logic
- Define the required fiber count: 2, 4, 6, 8, 12, 16 or 24 fibers.
- Select the fiber type according to the network design: OM1, OM2, OM3, OM4, G.652.D or G.657A.
- Check whether the route is mainly riser, horizontal, conduit or mixed indoor pathway.
- Confirm the acceptable outer diameter, tensile requirement and bending limitations for the installation route.
- Match the cable to the termination method, patching plan and fan-out needs before final approval.
When to consider alternatives
If the project needs a smaller breakout construction, compare this page with Mini Breakout Cable. If the installation needs a flatter duplex layout or a different breakout geometry, review I-V(ZN)HH 2x1 Flat DX or I-V(ZN)HH Break SZ.
