A chuck for holding an optical fiber in precise position includes first and second contiguous V-grooves, a chuck cover having a plurality of inter-leaving fingers for urging an optical fiber into the first V-groove so as to roughly position the optical fiber, and a plate for subsequently urging the optical fiber into the second V-groove for precise positioning of the optical fiber. The second V-groove is much smaller than the first V-groove and has a width which is less than the diameter of the optical fiber.
