The tube, the cable has a substantially sealed housing at least one optical conductor and an absorbent product the 1996

摘要

The invention relates to a cable to the tube substantially sealed housing at least one optical conductor and an absorbent product the hydrogène.la internal face of the tube (20), preferably metallic, is covered by a layer (22) of a material of catalysis - such as nickel or chromium - of the reaction of absorption of hydrogen by the absorbent product the hydrogen (30). the absorbent product of hydrogen is a filling material (30) of the tube or the form of a layer deposited on the layer of material of catalyse.la catalyst layer forms a coating for protection against corrosion of the tubing.
