WATERPROOF METAL PIPE-TYPE CABLE CONTAINING AT LEAST ONE OPTICAL WAVEGUIDE AND ONE HYDROGEN ABSORBING PRODUCT

摘要

the invention relates to a cable for metal tubethe at least one substantially leak proof and optical drivera hydrogen absorbing product.the inner surface of the tube (20) is covered by aa material layer (22) of a catalyst, such as nickel orchromium - reaction of absorption of hydrogen by thehydrogen absorbing product (30).the layer (22) is covered with a layer of at leasta layer of hydrogen absorbent, which is anfiller material (30) which form a tubelayer (52) is deposited on the layer of catalyst material (22).
