SUBSTANTIALLY WATERPROOF TUBE CABLE HAVING AT LEAST ONE OPTICAL CONDUCTOR AND A HYDROGEN-ABSORBING PRODUCT

摘要

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