Abstract: A novel self-aligning optical fiber connector is described which comprises a body member having an axial bore for receiving a lengthwise portion of the light-conducting core of a fiber optic cable, a pair of alignment projections and a pair of alignment slots disposed on one end of the body member in quadrature around the central bore and a clamp or other retainer near the other end of the body member to connect the cable sheath to the connector body. A connector assembly comprising two mating connector body members may be used to coaxially join a pair of abutting fiber optic cores.
