The present invention provides a fiber coupler twister used in fused taper process, in which two round plates having a plurality of holes thereon are each placed in the troughs of two pedestals respectively, and can be rotated. When manufacturing a fiber coupler, a plurality of fibers are each passing through the plurality of holes on the two round plates respectively, and then rotate the two round plates, so as to form various fiber couplers with different twisting angles.
