ABSTRACT:
The gap between end surfaces of optical converters provided at the ends of optical guide paths of optical fibers is maintained constant with a high accuracy and thereby optical coupling efficiency of such optical converters is stabilized with the structure of an optical fiber connector that both optical guide ends of optical guide path ends collide with each other, a recessed part is formed at least to the one surface of the optical guide ends and a constant gap is formed between the end surfaces of optical converters provided at the optical guide path ends.
