ABSTRACT:
A mono-fiber type optical fiber cord comprising: a coated optical fiber which is an optical fiber with a fiber coat therearound, a synthetic resin coat having a substantially rectangular sectional surface for further covering the coated optical fiber, and a reinforcing member within the coat for coated optical fiber, wherein the reinforcing member is located along one of the shorter sides of the coat in the substantially parallel direction with the shorter sides in such a manner as to be embedded along the longitudinally extending direction of the coated optical fiber. An optical cord ribbon is formed by mutually bonding the longer sides of the adjacent substantially rectangular sectional surfaces of a plurality of the mono-fiber type optical fiber cords, and thereafter by coating the external surface of the thus aligned optical fiber cords by a bundling coating method.
