ABSTRACT:
A connector having a body and a connecting portion is molded within a mold in which an end portion of an optical fiber is fixedly positioned. The end portion of the optical fiber consists of an exposed end portion of a core of the fiber and a terminal portion of a sheath of the fiber adjacent to the exposed end portion of the core. A molten mass of a selected synthetic material is injected into the mold at a melt flow rate of 5g/min, whereby the connector is molded integrally with the end portion of the optical fiber, such that the exposed end portion of the core is bonded to the connecting portion, while the terminal portion of the sheath is bonded to the body of the connector. The mold is maintained at a temperature not higher than the softening point of the optical fiber, and the molten resin mass is maintained at a temperature which is higher than the softening point but is not higher than a temperature 150.degree. C. higher than the softening point.
