Title:
OPTICAL SWITCH AND OPTICAL SWITCH SYSTEM HAVING THIS OPTICAL SWITCH
Document Type and Number:
Japanese Patent JP3425878
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To embody an optical switch which is capable of simultaneously executing optical switching between two optical fibers with each other among the optical fibers of respective sets by one switch drive in plural sets of the optical fibers of which each one set comprises the two optical fibers for constituting one optical transmission path.
SOLUTION: The optical fibers 101a and 101b, the optical fibers 102a and 102b, the optical fibers 103a and 103b and the optical fibers 104a and 104b are respectively formed as the sets and the mutual end faces of the two optical fibers of the respective sets face each other via a space propagation part 200 in the state in which the optical axes of the end faces are aligned to each other. The array type space optical switch 10 is composed of a shielding plate 300 which is inserted and removed into and out of the space propagation part 200 and the space propagation part 200. The optical switching in the optical fibers of the respective sets may be executed by the one operation of moving the shielding plate 300.
