OPTICAL FIBER CABLES AND COMPONENTS THEREOF CONTAINING AN HOMOGENEOUS BARRIER COMPOSITION CAPABLE OF PROTECTING OPTICAL FIBERS FROM HYDROGEN, AND RELATIVE HOMOGENEOUS BARRIER COMPOSITION

摘要

An optical fibers cable and the relative components comprise a barrier mixture, to protect the optical fibers, 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; said barrier mixture is a further object of the invention and consists of an homogenous phase.
