Patent ID: 6970615

Claim:
An optical switch comprising: a first dual-fiber collimator comprising a first pair of optical fibers, the first pair of optical fibers including a first input fiber and a first output fiber; a second dual-fiber collimator comprising a second pair of optical fibers, the second pair of optical fibers including a second input fiber and a second output fiber; a switching prism movable between a first position and a second position, wherein: in the first position, the switching prism is positioned to direct light from the first input fiber to the second output fiber, and direct light from the second input fiber to the first output fiber; and in the second position, the switching prism is positioned out of an optical path of light emitted from the first input fiber and the second input fiber; a first fixed planar mirror facing the first collimator separated from the switching prism, and aligned to reflect light from the first input fiber into the first output fiber when the switching prism is in the second position; and a second fixed planar mirror facing the second collimator separated from the switching prism, and aligned to reflect light from the second input fiber into the second output fiber when the switching prism is in the second position.
