Abstract
Abstract A module (6) for a fiber optic link has a case (20) housing a circuit module plate (24). An optoelectric element (30) mounted at a predetermined position of lead frames (26-2, 28-2) is molded from a transparent transfer molding material. The case (20) has a socket (18) for mounting a fiber cable connector (4) which is molded from a nontransparent injection molding material. A hole (19) in which is inserted a plug (14) of the connector (4) is formed in the socket (18) and the case (20). The optoelectric element (30) is arranged to oppose the hole (19) of the case (20) through a convex lens segment (36) of the plate (24).
