Optical switching connector.

摘要

Disclosed in an optical switching connector for switching in four stages provided with a first and second ferrule (21,22) disposed with end faces thereof abutting on each other and two reference pins (25) disposed in parallel at a predetermined interval. The first and second ferrules (21,22) have two parallel pin holes (23,24), respectively. The two reference pins (25) are inserted in the pin holes (23,24). The pin holes have an elongated sectional shape enabling the reference pins to move laterally by exactly a certain movement pitch. The first and second ferrules (21,22) are able to be positioned at one position determined by one of the inside surfaces of the pin holes (23,24) being pressed against the reference pins (25) and another position determined by the other inside surfaces of the pin holes (23,24) being pressed against the reference pins (25). One of the first and second ferrules (21,22) has fixed in it three more optical fibers (27a<2>27d) at a pitch of 1/n (n being a positive integer) of the above-mentioned certain movement pitch, while the other ferrule has fixed in it one or more optical fibers (29) so to correspond with all or part of the same. The movement pitch of the reference pins (25) in the pin holes (23) formed in the first ferrule (21) and the movement pitch of the reference pins (25) in the pin holes (24) formed in the second ferrule (22) are different. <IMAGE>
