ABSTRACT:
In order to restore quickly service which has been interrupted by damage in at least a portion of a cable, ends of optical fibers on one side of a damage location are spliced to optical fiber end portions of a restoration cable (70) within first and second closures (22,23) of a restoration kit (20). The first closure is attached to a foamed polymeric mounting pad attached to one flange of a deployment reel (100) mounted rotably on a payout spindle (135) which extends normally from one portion of a carrying case (21). Optical fibers of each end of the restoration cable are connected to splicing devices mounted in splicing modules (40,40) in the first and second closures. The second closure is moved from the case toward an opposite side of the damage location whereat fibers of the damaged cable on the other side of the damage location are extended into the second closure and spliced to the restoration cable therein. Because the first closure is attached to the deployment reel, the first closure turns with the reel as the reel is turned rotatably during payout of the restoration cable.
