A cable sorting and fusion splicing system (100) and method for arranging a plurality of optical fibers (17) in a cable in a predetermined sequence for fusion splicing to a multi-fiber optical connector (42). The cable sorting device 1 automatically sorts a plurality of optical fibers, such as twelve, loosely contained within a cable jacket (20). The fibers (17) are sorted in a predetermined sequence and maintained in a linear arrangement. The linear arrangement of fibers (17) is utilized at a fusion splicing device (40) to fusion splice to a multi-fiber optical connector having a corresponding sequence of optical fibers which are respectively fusion spliced to the optical fibers (17) of the cable. The fusion splicing device (40) is a mass fusion splicer which splices all of the fibers simultaneously.
