ABSTRACT A connector for connecting two groups of optical fibers in axial alignment comprises a recepticle having therein a bore extending through it for holding therein two plugs, one on each side. The surface of the bore has two flat portions, one at each end. The portions of the plugs to be inserted into the bore also has flat portions shaped to contact the flat portions of the bore surface. The shape of the bore and of the plugs are such that after the plugs are inserted into the bore with the complementary flat portions in contact. rotation of the plugs relative to the recepticle is thereby prevented or reduced and so that the two plugs are substantially fixed in postion relative to each other. Each of the two groups of optical fibers is connected to and fixed in position relative to the flat portions of the two plugs, so that after the two plugs are inserted into the bore, the two groups of optical fibers are axially aligned. Each plug includes a ferrule having therein a passage and whose cross-section is star-shaped or in the shape of a polygon. The plug also includes an insert shaped to fit into the passage with spaces between the insert and the passage surface. The optical fiber in a group are inserted into the spaces between the insert and the star-shaped or polygon-shaped surface of the passage in the ferrule for connecting the fibers to the plug and for fixing the positions of the optical fibers relative to the flat portion of the plug. The spaces between the insert and the ferrule of each plug are preferably tapered to facilitate the insertion of the fibers into the spaces.
