Optical fiber cables and components thereof containing a homogeneous barrier mixture, which is appropriate for protecting the optical fibers against hydrogen, and a relatively homogeneous barrier mixture

摘要

An optical fibers cable and the relative components comprise a barrier mixture to protect the optical fibers; said barrier mixture is a further object of the invention and consists of an homogeneous phase comprising (a) at least a silicon unsaturated organic compound having more than 0.2 mmoles of unsaturated groups per 100 g of said compound, (b) at least a catalyst selected from the group comprising inorganic and organic complexes of transition metals and organic salts of transition metals, and (c) at least an organic solvent substantially non-volatile.
