ABSTRACT:
An optical switch is constructed by: first and second optical switches each having ports of k inputs and k outputs; a third optical switch of k inputs and k outputs which can perform a bi-directional transmission; 2k first optical circulators; 2k second optical circulators; and 2k selecting switches. First to kth interfaces are connected by the first optical switch. (k+1)th to 2kth interfaces are connected by the second optical switch. The first to kth interfaces are connected to one of the (k+1)th to 2kth interfaces by the third optical switch. An optical crossconnect apparatus is also provided.
