ABSTRACT:
A fiber optic relay switch is provided for switching an optical signal from a first fiber to a second fiber. The switch comprises a pair of cylindrical members which are axially aligned and rotatable with respect to each other. Housed in the first member is at least a first optic fiber. In the second member is provided at least two optic fibers. A coupling face is provided between the ends of the first and second member. The fiber in the first member is terminated with the end of the fiber being aligned with the coupling face of the first member and is aligned with at least one of the two fibers in the second member. The two fibers in the second member are terminated with the ends thereof being aligned with the coupling face of the second member. When the members are rotated a predetermined angular amount the fiber in the first member is aligned with the other of the fibers in the second member. This enables the switching of optical signals provided from the fiber in the first member to the first of the fibers to be switched to the second of the fibers in the second member.
