Abstract: An optical fiber cable closure (20) includes a cable termination assembly (100) and a cover (23) into which the termination assembly is inserted. The cable termination assembly includes a cable entry (30) having an environmental seal through which cables (28--28) containing optical fibers are routed into the closure. The termination assembly also includes a support frame (101) which has a free end that extends from the cable entry and is enclosed by the cover. Extending upwardly from and attached to the support frame are a pair of spaced-apart parallel track members (112--112) for stacking optical fiber splicing trays (120) in a compact manner. Each tray includes a pair of spaced-apart openings (128--128) along one end. These parallel track members pass through the spaced-apart openings in the tray to create a slideable connecting arrangement which enables trays of varying thickness to be efficiently stacked within the same closure.

Abstract: A splice closure for optical fiber cables has an outer two pan shell, an interior longitudinally extending spine member held within the shell and cable sheath gripping members mounted on the ends of the spine member. A splice tray is removably mounted on the spine member intermediate its ends, and a plurality of splice holders are stacked on the splice tray. Each splice holder has grooves for containing the individual splices and means for affixing the individual splices to the holder. A splice tray cover contains means for applying compressive force to the stack of holders to hold them in place on the splice tray.

Abstract: An optical cable portion (10), resident within a cable closure (14), is caused to receive a water blocking arrangement which is effective to prevent water, which enters an internal cable portion (24) through an unintended cut (21) in an outer jacket (18) of a cable portion (20), from entering an interior of the cable closure. A plurality of water blocking materials (30 and 32) are coaxially disposed about the outer jacket and a core tube (26) of the cable portion, respectively, and cooperate with a heat shrinkable plastic tube (34) which substantially covers the water blocking materials to prevent the movement of water from the internal cable portion past the water blocking materials.

Abstract: A closure (20) which may be used temporarily in the restoration of service to an optical fiber cable (50) which has been damaged includes a base (22) and a cover (24) which include mating longitudinal edge portions. The base and the cover are secured together with longitudinally extending C-clamps (97--97) which are moved slidably to engage the mating longitudinal edge portions of the base and the cover. Cables to be spliced enter the closure through openings in compliant end blocks (67--67). Modules (40,40) are disposed within the closure and hold connective devices used to make connective arrangements between optical fibers of the cables. The closure is easy to assembly is lightweight and may be reused.

Abstract: An optical fiber closure (20) which is particularly suitable for connecting small fiber count cables and for repairs of same includes a longitudinally extending electrical bonding and support member (70) for supporting in-line connections between optical fibers of cable end portions which enter the closure from opposite ends thereof. Each cable end portion extends through a cable and clamping and sealing means (40) which is adapted to become secured to a tubular member (60) in which is disposed the support member and which is adapted to provide sealed engagement with the entering cable end portion to prevent the ingress of moisture.

Abstract: An optical fiber cable closure (20) includes a cable termination assembly (26) and a cover (28) into which the termination assembly is inserted. The cable termination assembly includes an end plate assembly (34) through which distribution cables (21,22) to be spliced extend. From the end plate is cantilevered a distribution portion (106) which supports an optical fiber organizer (115). Mounted on the fiber organizer adjacent to a longitudinal edge thereof are a plurality of stacked organizing modules (120,120). Each module includes a plurality of nests (134-134) for receiving splicing devices such that the axes of the fibers in the devices are parallel to each other and to an axis of the closure. Optical fibers from each incoming cable are routed in individual bundles or as ribbons from the distribution portion to selected ones of the modules.

Abstract: A design for an underwater splice closure is disclosed that protects splices essentially independent of operating depth, while allowing for ease of use and low-cost manufacture. The primary splice housing consists of an upper and a lower half-cast of beryllium copper. The splices are made and then organized along a series of interior trays mounted from risers attached to the lower half of the housing. The two halves bolt together. An end-seal assembly contained on the lower half of the closure, and consisting of a series of O-ring applications, receives the sheathed cable and directs it to a mounting means which secures the sheath to the lower half of the splice closure. The invention is particularly adapted to optical fiber splice closures which require protective fill.
