Central Loose Tube Non-Metallic U-DQ(ZN)BH
Designed for indoor backbone and building distribution where higher reaction-to-fire performance is specified.
Fiber optic and data LAN cables from UPCOM cover indoor, outdoor, FTTH, CPR-rated, armored and specialty network projects. This page groups the cable families by real buying logic so you can move directly from requirement to the right product route.
CPR class is one of the first filters when the route is inside a building and fire performance is part of the specification. The guide page remains the main CPR explainer; the certificates page is kept separate as proof and document support.

Designed for indoor backbone and building distribution where higher reaction-to-fire performance is specified.

Combines an armored construction with B2ca performance for projects requiring both fire continuity and stricter reaction-to-fire classification.

Suitable for building infrastructure requiring an armored construction and Dca performance above the basic Eca level.

A non-metallic Dca construction for projects evaluated through datasheet and CPR documentation.

Suitable where basic CPR performance is accepted and neither Dca nor B2ca is specified.
When the route includes outdoor exposure, buried sections or higher mechanical risk, construction and protection level usually matter before connector or core-count detail.

Metallic armor provides added mechanical protection for outdoor cable routes.

Combines armored loose-tube construction with an LSZH jacket for routes where mechanical protection and fire behavior both matter.

A PE-jacketed multi-loose-tube construction for outdoor distribution routes requiring organized fiber grouping.

A multi-loose-tube construction with an LSZH jacket for indoor or protected routes where PE is not preferred.

Use tactical cable when the installation scenario is operationally different from standard fixed building or permanent outdoor infrastructure.
Indoor cable choice is usually driven by pathway density, handling, breakout requirement and termination logic. This is where breakout, duplex, simplex and pigtail routes separate.

A compact tight-buffer cable for indoor pigtail and termination applications.

Use mini-breakout cable when the project needs a smaller indoor structure than classic breakout while keeping organized sub-unit handling.

A flat duplex construction for compact indoor links and controlled short-distance connections.

A breakout construction with LSZH behavior and reinforced sub-units for structured indoor handling.

A traditional breakout construction for indoor distribution where individually protected sub-units are preferred over mini-breakout or duplex formats.

A compact simplex cable for short indoor links and individual fiber connections.
FTTH drop cable selection is driven by last-mile handling, aerial or indoor use, reinforcement type and installation speed. It should not be mixed with backbone cable logic.

An indoor FTTH drop cable for subscriber-side connections within buildings.

A flat aerial FTTH drop cable with FRP messenger support for last-mile deployment.

An aerial FTTH drop cable with steel strength members for last-mile access networks.
Some projects do not sit cleanly under standard indoor or outdoor backbone logic. These routes cover specialty armored and application-specific cable families that still belong under the main cable category.

A specialty armored construction for applications requiring more mechanical protection than standard premises cable.

A tight-buffer breakout construction for specialty applications requiring organized sub-units, LSZH behavior and added mechanical protection.
This category also covers copper data LAN cables for structured cabling. Selection depends on Ethernet category, shielding type and network architecture.









The fastest way to narrow the RFQ is to fix four decisions first. This section is written as a practical route, not as a long repeated paragraph.
Start with the real route: indoor, outdoor, FTTH or copper LAN. This removes most wrong options immediately.
If the route is inside a building, confirm whether B2ca, Dca or Eca is required before choosing the rest of the construction.
Decide whether the route needs armored, non-metallic armored or standard non-armored construction.
Then match the cable choice with patch panels, fiber connectivity, FTTH deployment or cable blowing machine needs.
Use these links when the selection is moving from broad category review into compliance, documents, installation method or related infrastructure support.
