Abstract: A penetrable interface configured to separate two or more spaces can include an elastomeric seal having a first segment and a second segment. A portion of the second segment can be integrally formed with a portion of the first segment. The first and second segments can create a sealing engagement therebetween in the absence of an applied force on the second segment. The first and second segments can be distorted out of sealing engagement when subjected to the applied force on the second segment.

Abstract: A plug and receptacle electrical connector can be repeatedly connected and disconnected in harsh environments such as seawater. The plug unit has blade-like pins with insulated shafts and conductive tips. The plug unit engages the receptacle unit housing socket contacts within closed, nested, oil-filled chambers. The chambers are pressure balanced to the in-situ environment and to each other and employ positive means to remain sealed before, during, and after mating and demating.

Abstract: An apparatus and method for managing one or more flexible lines such as optical fibers, wherein each fiber has two fixed ends. Optical fibers are arranged in a curved figure-eight pattern lying in three-dimensions and having two adjacent loops on the exterior curved winding surface of a tubular shell. The configuration is guided by winding tracks lying axially on the exterior side of shell. The curvatures of the shell and winding tracks are such that the bend of the managed fibers is everywhere equal to or greater than the fiber minimum bend radius.

Optical fibers are arranged in a curved figure-eight pattern lying in three-dimensions on the exterior curved winding surface of a tubular shell. The configuration is guided by winding tracks on either exterior side of shell.

Abstract: An apparatus and method for sealably joining cables to pressure-balanced submersible junction boxes. The apparatus maintains a balanced pressure within the termination chamber; it is field installable, testable, and repairable. The termination chamber is not oil-filled; instead, it is substantially filled with a solid particulate fill material. An apparatus and method for sealably containing the cable's bitter end within the termination chamber are further provided. The apparatus includes a cable termination assembly having a chamber with a first end including a load bearing cable-attachment to sealably join a cable to the chamber, and a second end including an underwater connector. Within the chamber one or more optical and/or electrical conductors from the cable are terminated to respective one or more attachment points of the connector. The apparatus prohibits cable pistoning into the termination chamber.
