PROBLEM TO BE SOLVED: To provide an improved attenuating element capable of being used in coupling to all types of optical fibers. SOLUTION: The attenuating element is provided with a block shaped head, the head is provided with a tapered side wall and a chamfered part extending along the side wall and the lower flat surface, a neck is extended from the lower flat surface of the head and further an attenuating disk is extended from the neck. The attenuating element is assembled and arranged so as to incline at the angle of 90 deg.-82 deg. to the longitudinal axis of a matching sleeve used in coupling to the optical fiber. Thus, the attenuating element is adaptable to coupling to the optical fiber in either case when the end surface of a ferrule is mutually matched or inclined to the longitudinal axis of a matching sleeve. Also, the attenuating element is selectively assembled and arranged so as to rotate between facing ferrule end surfaces within the matching sleeve with respect to the longitudinal axis of the attenuating element. |
