Abstract
Amorphous metallic material in ribbon form is employed to provide hermeticity of cable elements, particularly optical fibres. The metallic glass CuZr has a low permeability for hydrogen, particularly when erbium is included. Thus sealing optical fibres (1) in amorphous metal tubes (3) will prevent increase in attenuation of such fibres when used in submarine cables by preventing contact with hydrogen generated in such cables during use thereof.
