Patent ID: 6929405

Claim:
An optical communication module, comprising: an optical fiber; a light-receiving device for converting beams of light emitted from the optical fiber to an electric signal; and a receiving optical section for coupling the beams of light emitted from the optical fiber with the light-receiving device, wherein, the receiving optical section includes: a collecting optical system for directing at least a part of beams of light, which is emitted from the optical fiber, to the light-receiving device; and at least one interference restraining section for restraining module-reflected beams of light reflected in a part of the optical communication module from being coupled with the optical fiber, said at least one interference restraining section being provided in an area irradiated with at least a part of the module-reflected beams of light; and wherein the collecting optical system is a reflecting mirror for reflecting the beams of light emitted from the optical fiber so as to lead the beams of light to the light-receiving device.
