Abstract: An optical fiber coupler and manufacturing apparatus and method thereof aim to provide a loading fixture and a clamping device to fabricate 1×4, 2×4 and 4×4 optical fiber couplers, and also improve driving mechanisms and operation of the packaging station and the entire manufacturing equipment. The 1×4 optical fiber coupler fabricated by means of the invention can split an optical signal more evenly and has a higher production yield. The total size of the equipment is smaller and the structure is less complicated, and the construction cost is lower.
