A single channel optical slip ring assembly comprising a hollow rotor shaft selectively dimensioned for receiving a fiber optic cable, a rotor bushing mounted in the rotor shaft and having an axial bore for receiving an optic fiber of a fiber optic cable, a stator cylindrical member selectively dimensioned for receiving a fiber optic cable, and having on one end an axially extending collar, a stator bushing mounted within the stator proximate the collar having an axial bore for receiving an optic fiber in each end thereof, means for rotatably mounting the bushing end of the rotor shaft within the collar of the stator cylindrical member so that the rotor bushing bore and the stator bushing bore are aligned along the axis of rotation and the bushings are separated by a selected gap, a gauging bore in the stator bushing which orthogonally intersects its axial bore, means in the stator cylindrical member for permitting access to the gauging bore, a stator fiber optic cable in the stator cylindrical member having an exposed length of optic fiber extending into the stator bushing bore to a selected gauged location within the gauging bore, and a rotor fiber optic cable in the rotor shaft having an exposed length of optic fiber passing through the rotor bushing bore, across the gap, and into the stator bushing bore to a selected gauged location spaced from the stator optic fiber within the gauging bore, whereby the rotor optic fiber rotates within the stator bushing and the fiber ends are maintained spaced from one another and in axial alignment thereby.
