ABSTRACT OF THE DISCLOSURE A fiber optic relay switch is provided for switching optical signals from a first to a second signal- receiving fiber. The switch comprises a pair of cylindrical members defined by cylindrical surfaces forming interstitial fiber channels. The members are axially aligned and rotatable with respect to each other. At least one optic fiber is housed in a passageway of the first member and at least two optic fibers are housed in the channels of the second member. A coupling face is provided between the ends of the first and second members. The fiber in the first member terminates in alignment with the coupling face of the first member and is also aligned with at least one of the two fibers in the second member. The two fibers in the second member are terminated with their ends 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. Thus, optical signals emanating from a signal-emitting fiber in the first member may be switched between the fibersin the second member.
