Abstract: A waterproof wire-sockets electrical junction cover suitable for use in wet environments includes a chamber to house the wire-sockets electrical junction. Sealable passages on one end of the chamber allow electrical wires to pass into the chamber. On the other chamber-end, a sealable port allows the wire-sockets itself to enter the chamber. The electrical wires are mechanically and electrically joined using the wire-sockets. The resulting junction is then drawn through the aforementioned sealable port into the chamber. The port is closed, thereby completely watertight sealing the wire-sockets electrical junction.

Abstract: A low-loss, underwater-mateable optical fiber connector is provided which permits connection between a pair of optical fibers through a fiber-to-fiber butt junction effected by a pair of connector units. Each connector unit houses a fluid-tight interior chamber. A fiber junction contained in one chamber includes an alignment device holding the terminal end of one fiber. The other interior chamber contains a fiber guide and transport mechanism which, when actuated by the joinder of the connector units, provides a fluid-resistant, pressure compensated channel between the chambers and advances the terminal end of the other fiber through the channel to the junction where it is guided into the alignment device to be butt-joined with the one fiber.
