## Abstract

An optical fiber shuffle for recombining a plurality of optical fibers of a first optical cable into a second optical cable includes a fixing rod, a first fixing plate, and a second fixing plate. The first fixing plate defines a plurality of first fixing grooves. The first fixing grooves are configured to respectively receive the plurality of optical fibers of the first optical cable. The second fixing plate defines a plurality of second fixing grooves. The second fixing groves are configured to respectively receive the plurality of optical fibers of the first optical cable after the plurality of optical fibers is wound around the fixing rod and recombined into the second optical cable. The first fixing plate and the second fixing plate are respectively located at two ends of the fixing rod.
