Patent ID: 7373050

Claim:
An optical communication module for performing single-core bi-directional communication, comprising: an optical fiber; a light-emitting element for emitting light; and a photoreceptor element for receiving light, wherein said optical fiber has an end face at one end, said end face having an angled portion forming a reflecting surface; wherein either one of said light-emitting element and said photoreceptor element is arranged adjacent to an end of the fiber along an axis of light propagation and faces said end face of said optical fiber, and the other of said light-emitting element and said photoreceptor element is arranged adjacent an outer surface of said optical fiber in a radial direction from the center of the optical fiber and faces said reflecting surface; and wherein said photoreceptor element is arranged outside a maximum diffusion range of the light emitted from said light-emitting element, and wherein said end face of said optical fiber further includes a non-angled portion.
