OPTICAL COUPLER AND PROCESS FOR PREPARATION THEREOF ABSTRACT OF THE DISCLOSURE An optical coupler comprising N number (where N stands for an integer of not less than 2) of optical fibers having one ends integrated and the other ends branched and N number of optical coupler parts, wherein the top end of each light branching-coupling optical fiber has a plane of 360°/N including an inclined branching fiber-abutting plane inclined at an angle .theta. to the optical fiber axis and a light-coupling plane vertical to the abutting plane, each of the optical coupler parts is constructed by inserting the light branching-coupling optical fiber in an optical fiber- retaining hole of a block having the same plane as the branching fiber-abutting plane of the optical fiber and a light-coupling plane vertical to the abutting plane, and the branching fiber-abutting planes of the optical coupler parts are engaged with each other to construct a optical coupler.
