Fibre optics is the most reliable solution for telecommunications in extensive areas.

OPTRAL offers one type of cable for every installation type: from the trunk to the distribution, buried, aerial cables, or cables inside conducts.

Both road and rail infrastructures, as well as urban networks, require cables with high fibre density, large broadband and excellent mechanical protection.

Cables for tunnels can be installed in conducts or attached to walls.

OPTRAL offers many cable designs which fulfil security measures and requirements in the event of fires in tunnels. All features always with the most competitive cost.
