BIDIRECTIONAL OPTICAL TRANSMISSION DEVICE

摘要

In a bidirectional optical transmission device, a light-emitting element and a light-receiving element are mounted on one side of a base material and are sealed with an optically permeable resin section. The resin section includes a light emitting side resin section and a light receiving side resin section, and a slit is provided between these resin sections. The device further includes a light-blocking receptacle having a claw, and the claw of the receptacle is disposed in the slit between the light emitting side resin section and the light receiving side resin section. The claw of the receptacle prevents leakage of light from the light-emitting element between the light-emitting element and the light-receiving element.
