Abstract: A splice tray for holding and protecting optical fiber splices within a splice closure is adapted to be mounted on support members within the closure. The tray has a longitudinal axis and passages formed therein for holding and guiding the fibers to a splice area of the tray while protecting them from being bent too sharply. A splice holder insert is removably mounted to the splice tray in the splice area, and has a plurality of alternating pass-through channels and splice holding channels extending parallel to the longitudinal axis of the tray and arrayed across the width of the tray in two such arrays, longitudinally spaced from each other. In one embodiment, each of the splice holding channels is defined by a wall of a pass-through channel and a longitudinally extending a resilient member. In this embodiment, resilient fiber holder is located at each end of each pass-through channels. In another embodiment, the splice holding channels are defined by U-shaped end members at each end of the channel.

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: An optical fiber cable closure assembly includes a base member and a mating cover which, when assembled form a hollow splice closure with openings at each end. Mounted to the base member at at least one end thereof is a grip block assembly which grips the optical cable entering the adjacent open end, and which automatically adjusts to differing sizes of cables. The grip block assembly has an upper member and a lower member and includes first and second pivotally mounted arms on the lower member which are actuated by actuating pins on the upper member and which, as the upper member is tightened down on the lower member, pivot until they bear against and grip the cable. Included within the closure assembly are one or more optical fiber splitters which are used to separate and segregate individual fibers or groups of fibers to be spliced.

Abstract: A closure includes an end plate assembly (20) which includes an inner and an outer endplate and between which is disposed a cable sheath gripping assembly (60). The cable sheath gripping assembly includes a housing (62) and a clamping portion (100) which cooperate to form two cable-receiving passageways. Each passageway is formed between two channels, one being formed in the base and one being formed in the clamping portion. Each channel is provided with a plurality of inwardly extending circumferential and axial ribs with the ribs cooperating to clamp a cable end portion extending therewith. The engagement of the ribs with the cable end portion under compressive engagement caused by the turning of a bolt 106 into threaded insert of the housing provides enhanced resistance to pullout and rotation of the cable end portion.

Abstract: An optical fiber cable closure (20) includes a cable termination assembly (22) and a cover (23) into which the termination assembly is inserted. The cable termination assembly includes two spaced end plates (34,36) through which cables (28,29) to be spliced extend. One of the end plates supports a frame (101) which supports a plurality of optical fiber splicing trays (120--120). Adjacent end portions of the trays are staggered and hinged so that some trays may be moved pivotally to expose others. Optical fibers from each incoming cable are routed in individual tubes (115--115) or as ribbons from an optical fiber breakout (110) mounted in the frame to selected ones of the trays. Hinge lock plates (130--130) which complete a hinge for each tray also serve to clamp the tubes incoming to each tray to prevent unintended movement. Each of the trays may be provided with a plurality of organizing modules (140,140) each of which is adapted to hold a plurality of optical fiber connective devices.

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 platform frame assembly for attachment to a portable exhibit display, the platform frame assembly having pivotal display frame members which are engageable against the portable exhibit display in an interlocking arrangement; the platform frame assembly having a plurality of horizontal shelves supportable by the frames for providing a projecting platform as an attachment to the portable exhibit display.

Abstract: A telecommunication cable splice closure is disclosed comprising a pair of elongated covers (10) having semi-cylindrical interior walls (12) extending radially about a closure axis (15). Two flat end walls (16) extend from opposed ends of each interior wall normal to the closure axis. A pair of cable clamp supports (22) is provided having annular rims (24) sized to be positioned with the cover interior walls (12) about a cable (46) in flush or in point contact with the end walls (16). Means (52) are also provided for securing the pair of covers (10) together about the clamp supports (22).
