A splice closure including a frame having a partition wall to define front and rear access areas for the closure. The frame carries one or more splice trays on a first surface portion making the splices accessible from the front or first access area. A slack storage compartment is provided on the second surface portion. The slack storage compartment includes one or more pairs of opposing sidewalls that define an access opening for the slack that is accessible from the rear access area. An extension member for the frame is disclosed for obtaining greater amounts of slack from the cable, such as for a taut sheath cable splice. A tandem longitudinal arrangement of splice trays is also disclosed and may be used for a taut sheath ring splice or for repairing a severed cable. |

DETAILED DESCRIPTION In view of the foregoing background, it is therefore an object of the present invention to provide a splice closure for securing optical fiber splices and slack, while facilitating initial access and reaccess to either the slack or the splices without disturbing the other.
It is another object of the present invention to provide a splice closure and associated method for facilitating splicing of a drop cable, for example, to a fiber optic cable that has already been installed, such as in a taut sheath fiber splice.
It a further object of the present invention to provide a splice closure and associated method for repairing a damaged fiber optic cable.
These and other objects, features, and advantages of the present invention are provided by a splice closure including an elongate frame and partition wall means for defining opposing front and rear, or first and second, opposing access areas for splice organizer means and slack storage means.
In other words, the splice closure according to the invention permits access to the splices and slack relative independent from one another, thereby facilitating initial assembly and reaccess within the splice closure.
The wall partition means defines surface portions extending longitudinally between opposing ends of the frame.
Thus, the splice organizing means is on the front or first surface portion so that the splices are accessible from a first access area, while the slack storage means is on the second surface portion of the partition wall means and stores slack optical fibers so that the slack is accessible from the second access area.
The slack storage means preferably includes one or more pairs of opposing spaced apart sidewalls depending from the wall partition means and defining a slack storage access opening for facilitating access to the slack optical fibers from the second access area.
In one embodiment of the splice closure, the splice organizing means preferably includes a plurality of splice trays, and mounting means for mounting the splice trays in a stack
