Our optical-fibre building cable & entry systems are specifically designed for the insertion of microducts into buildings to connect subscribers to the fiber optic network. They can also accommodate other media conductors, such as copper telecommunications cables or oval cables. Suitable for installation in most common wall types, such as waterproof concrete, brick, or hollow blocks, they offer maximum flexibility. During development, particular attention was paid to ensuring that the outer flange and the expanding foam conduit are perfectly matched. This allows for controlled foaming of the outer flange and along the borehole/media conductor, resulting in a high-quality and reliable seal.
