Abstract: This disclosure provides systems, methods, and devices for connecting optical fibers. In one aspect, a connector includes a transfer tube for equalizing the pressure between two chambers within the two connectors when the connectors are mated. The chambers may house biasing elements coupled to optical fiber holders to provide a pressure independent force against optical fiber terminals. The optical fiber holders may include side openings for receiving optical fibers.

Abstract: An underwater electrical connector includes a plug shell, a receptacle shell, and removeable inserts. A substantially water tight seal is provided between the plug and receptacle shells when engaged, and preferably the plug shell and the socket shell have a maximum diameter of less than approximately 0.75 inches. In some embodiments, the plug and receptacle inserts are held in place with retaining rings comprising a shape-memory alloy. A low profile key having one portion flush with a shell surface may be provided, as well as an optional insert mounted oil valve.

Abstract: An underwater electrical connector comprises a pair of mating plug and socket connector shells each containing a contact carrying insert body. When the shells are connected together, contact pins projecting from the front face of one of the insert bodies engage in corresponding contact sockets on the front face of the other insert body. The connector shells have an interengageable key and keyway formation for maintaining correct orientation as they are secured together. Each insert body has a keyed engagement with its respective shell as it is inserted. One of the insert bodies has a rearwardly projecting sleeve which engages in a corresponding rearwardly projecting sleeve on the respective connector shell as it is inserted. The shell sleeve has an axial through slot extending from its free end, and the insert body sleeve has a corresponding outwardly projecting key for engagement in the through slot.
