摘要： A method of dry-mating a first connector part and a second connector part wherein the first and second connector parts are brought into a first mated state, wherein a seal is engaged between the first and second connector parts. A sealed inner space is formed between the first and second connector parts. The sealed inner space is evacuated through an evacuating port. The evacuation port is arranged such that it is located on an inner sealed side of the engaged seal in the first mated state. Further, the first connector part and the second connector part are brought into a second mated state, wherein a seal is engaged between the first connector part and the second connector part such that the evacuation port is located on an outer side of the engaged seal so that it is no longer in flow communication with the sealed inner space.

摘要： The present invention generally relates to an inline pressure compensator that compensates for volumetric changes within Field-Assembled Cable Termination (FACT) structures when exposed to high pressures and extreme subsea depths by transferring a pressure compensating fluid into the internal cavity of the FACT. The present invention may comprise a flexible internal component and an outer shell-like component. The inner component may comprise two concentric rings of edge-welded bellows that are joined together and wrapped around inner components of the termination or of the inner portion of the outer component. The inner void in the bellows may be filled with pressure-compensating fluid. The pressure compensating fluid diffuses directly into the fluid-filled cavity of the termination assembly. The exterior component may comprise a housing adapted to protect the interior bellows component and provide for seawater to fill the space around the periphery of the bellows arrangement.

摘要： A multiple conductor optical cable may be coupled to an undersea device, such as a cable joint, branching unit, or repeater, with one or more isolated bypass conductive paths being provided across the undersea device. At least one conductor may be terminated within a housing of the undersea device and at least one conductor may be coupled to a conductive bridge member that provides the isolated bypass conductive path across the device. Multiple conductor optical cables may be coupled to undersea devices in optical networks using independent power paths, for example, to deliver power to different powered components at different voltage potentials.
