An optical transmitting and/or receiving module comprises an optical plug comprising a housing which is provided with at least one ferrule assembly having an optical fiber therein, a main receptacle body connected to the optical plug, and an optical link assembly comprising a substrate. The substrate has at least one optical semiconductor element and circuit elements for signal processing fixed thereon. The optical link assembly is fixed to the main receptacle body so that the at least one optical semiconductor element opposes a tip end of the optical fiber of the optical plug and a surface of the substrate is perpendicular to an optical axis of the optical fiber.

DETAILED DESCRIPTION Accordingly, it is a general object of the present invention to provide a novel and useful optical transmitting and/or receiving module in which the problems described heretofore are eliminated.
Another and more specific object of the present invention is to provide an optical transmitting and/or receiving module comprising an optical link assembly and a main receptacle body, wherein the optical link assembly comprises a substrate having at least one optical semiconductor element and circuit elements of a signal processing circuit mounted thereon and the optical link assembly is mounted on the main receptable body so that a surface of the substrate is perpendicular to an axial direction of the main receptacle body.
In other words, the surface of the substrate is perpendicular to an optical axis of an optical fiber within an optical plug which is connected to the main receptacle body.
According to the optical transmitting and/or receiving module of the present invention, the optical link assembly is downsized, and the optical link assembly does not project from the main receptacle body.
As a result, the overall size of the optical transmitting and/or receiving module can be reduced.
Other objects and further features of the present invention will be apparent from the following detailed description when read in conjunction with the accompanying drawings.
