Abstract
Disclosed in an optical switching connector provided with a first and second ferrule disposed with end faces thereof abutting on each other and two reference pins disposed in parallel at a predetermined interval. The first and second ferrules have two parallel pin holes, respectively. The two reference pins are inserted in the pin holes. 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 are able to be positioned at one position determined by one of the inside surfaces of the pin holes being pressed against the reference pins and another position determined by the other inside surfaces of the pin holes being pressed against the reference pins. One of the first and second ferrules has fixed in it two or more optical fibers 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 so to correspond with all or part of the same.
