Central Loose Tube Non-Metallic U-DQ(ZN)BH
Use this family where higher reaction-to-fire performance is required for indoor backbone and building distribution.
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.

Use this family where higher reaction-to-fire performance is required for indoor backbone and building distribution.
Use this route where fire continuity and higher CPR performance both matter in the same project scope.

Use this route when the specification needs a stronger CPR profile than Eca but not the tighter B2ca route.

Use this route when the project needs a Dca non-metallic construction and the selection is being driven by document review.

Use this option where the specification allows basic CPR performance and the route does not require Dca or B2ca.
When the route includes outdoor exposure, buried sections or higher mechanical risk, construction and protection level usually matter before connector or core-count detail.

Use this family where the route needs outdoor structure with stronger metallic armor support.

Use this route where fire behavior and armored outdoor performance both influence the cable decision.

Use this family where the route is outdoor and the project is driven by loose tube grouping rather than indoor premises logic.

Use this family where the project needs loose tube architecture with LSZH behavior instead of PE.

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.

Use this family when the indoor route is simple and termination logic is centered on pigtail use.

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

Use this route where the project is built around duplex indoor connection logic and controlled short internal paths.

Use this route when the cable needs breakout logic with tighter indoor handling and LSZH behavior.

Use this route where the project needs a more traditional breakout structure instead of mini-breakout or duplex formats.

Use this route when the installation is centered on simplex internal connections and minimal path complexity.
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.

Use this route where the FTTH drop path is fully internal and the project is close to subscriber connection logic.

Use this route when the FTTH drop path is aerial and the installation needs a flat messenger-supported profile.

Use this route when the aerial drop needs steel-supported structure and the installation is part of last-mile access deployment.
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.

Use this route when the project needs a specialty armored construction that sits between standard premises and more exposed use cases.

Use this route when the selection is driven by tighter buffer logic and specialty application fit rather than standard cable family labels alone.
This category also covers the copper-side data LAN series. Use this route when the project is structured copper cabling rather than optical distribution, and the selection depends on Ethernet class, shielding 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.
