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. Optical fibers from each incoming cable are routed in individual tubes (29--29) or as ribbons from an optical fiber breakout (140) mounted on the frame to selected ones of the trays. The trays are provided with a plurality of organizing modules (125--12…
