Abstract

An underwater optical fiber cable (20) which is substantially free of hydrogen generation includes a core portion (22) which includes an optical transmission medium and which may comprise a terrestrial cable and a sheath system which may be an oversheath for the terrestrial cable. An outer portion of the sheath system includes a plurality of longitudinally extending strength members (42--42) each being made of a metal having a relatively low chemical or electrochemical reactivity. Covering individually each strength member is a plastic material (60) such as polyethylene.
