Fibre optics cables and related components containing a barrier composition capable of protecting the smooth fibre optics against hydrogen on structure of smooth barrier.

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 homogeneous phase.
