Abstract: An underwater rolling seal connector assembly has releasably mateable plug and receptacle units with one or more rolling seals mounted in front faces of receptacle and plug units. The rolling seals are rotatable back and forth between a closed position sealing one or more chambers within the respective units which contain one or more contacts and an open position in which bores through the seals are open to allow contacts in one unit to pass through the seal openings and engage contact in the other unit. Actuators automatically rotate the rolling seals into the open position during mating and back into the closed position on de-mating. At least one actuator assisting device is located in at least one of the units and associated with the rolling seal in that unit to bias the seal back to the closed position during de-mating.

Abstract: A subsea connector unit with an integrated, bi-directional electrical to optical (EO) media converter is provided which has a first end configured for connection to standard subsea electrical cable connector unit and a second end joined to a subsea optical or electro-optical ethernet jumper cable. The EO media converter has one or more electrical input/output (I/O) junctions which communicate with electrical signal conductors in a connected electrical ethernet cable and one or more optical I/O junctions which are connected to one or more optical fibers extending from the subsea jumper cable. Electrical input signals received at the electrical I/O junctions are converted into corresponding optical signals provided at the optical I/O junctions for transmission along the subsea jumper cable, and optical input signals received from the jumper cable are converted to electrical signals at the electrical I/O junctions for output to the electrical cable.
