Abstract
Abstract Connection device for connecting a submarine repeater and a coaxial cable having an outside conductor made of aluminum, comprising particular means to be implemented for connecting a repeater to a submarine cable of the coaxial type whose outer conductor is made of aluminum, these means being imposed by the necessity of avoiding the forming of an electrochemical couple between the aluminum of the line cable and the copper of the connecting cable of the repeater having sea water as its electrolyte.
