B2ca Fiber Optic Cables
Use B2ca cable families when the project explicitly requires stronger reaction-to-fire performance for building interiors, regulated environments or more restrictive end-user standards.
Fiber optic and data LAN cables from UPCOM cover indoor, outdoor, FTTH, CPR-rated and armored network projects. Start with the correct cable family below, then move directly to the product page, guide or document route that matches the RFQ.
CPR class is one of the first filters when the route is inside a building and fire performance is part of the specification. Use the correct class according to the project requirement rather than defaulting to the highest label.

Use B2ca cable families when the project explicitly requires stronger reaction-to-fire performance for building interiors, regulated environments or more restrictive end-user standards.

Dca cable families fit projects that need stronger fire performance than Eca but do not require the tighter B2ca route.

Eca routes are used when the specification allows basic CPR performance and the project does not require the more restrictive B2ca or Dca classes.
When the route includes external exposure, buried sections or stronger mechanical risk, construction and protection level usually matter before connector or core-count detail.

Use armored outdoor cable when the route needs stronger protection against impact, crush risk or tougher handling conditions.

Use multi loose tube constructions where route length, fiber grouping or outdoor distribution logic makes loose tube design the more suitable choice.

Use tactical cable when the installation is operationally different from 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, mini-breakout, duplex and pigtail routes separate.

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

Use breakout fiber optic cable where the route needs clearer direct breakout structure and stronger sub-unit handling inside the building.

Use duplex and pigtail structures where the project is focused on internal connection logic, compact indoor routing or defined termination points.
FTTH drop cable selection is driven by last-mile handling, indoor or outdoor use, reinforcement type and installation speed. It should not be mixed with backbone cable logic.

Use indoor FTTH drop cable where the route is fully internal and the installation is close to subscriber connection logic.

Use metallic armored FTTH drop cable where the drop path needs added protection and stronger route stability.

Use aerial FTTH drop cable where the route includes messenger-supported aerial last-mile deployment.
This category also covers data LAN cables. Use this route when the project is copper-side structured cabling rather than optical distribution, and the selection depends on Ethernet class, shielding and building network architecture.

Use Cat6 routes when the project is centered on structured copper cabling, newer LAN performance requirements and general building network infrastructure.

Use Cat5e routes where the project is structured copper cabling but the requirement does not justify moving into higher copper categories.

Keep copper LAN selection separate from fiber optic backbone or FTTH selection. This avoids mixing two different buying logics in one RFQ.
The fastest way to narrow the RFQ is to fix four decisions first. This section is written as a practical selection route, not a generic paragraph block.
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 actually required before choosing the rest of the construction.
Decide whether the route needs armored, non-metallic armored or standard non-armored construction.
Then connect the cable choice with fiber patch panels, fiber connectivity or cable blowing machine needs.
Use these links when the selection is moving from broad category review into compliance, installation method or support documents.
Use UPCOM CPR guide to compare cable classes, or check the official European Commission CPR page for background reading.
UPCOM CPR guideUse cable blowing machine and fiber connectivity routes when the cable choice must be matched with installation or termination equipment.
Cable blowing machinesUse FTTH and general fiber overview pages when the project is still at concept stage and the cable type is not fully fixed yet.

No. The correct CPR class should match the project requirement, not just the highest label available.
Use armored constructions when route conditions create higher mechanical risk, stronger handling exposure or added protection demand.
Yes. Share the route, environment, CPR requirement and quantity scope first. That is enough to narrow the right family quickly.
