Abstract
An optical communication module in accordance with the present invention includes: an optical fiber; a light-receiving device for converting the beams of light emitted from the optical fiber to an electric signal; and a receiving optical section for coupling at least a part of the beams of light emitted from the optical fiber with the light-receiving device. The receiving optical section includes: a collecting optical system for directing at least a part of the beams of light emitted from the optical fiber to the light-receiving device; and an 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, the interference restraining section being provided in an area irradiated with at least a part of the module-reflected beams of light. The optical communication module and a single fiber bi-directional optical communication module using the same realize full-duplex communications using a single optical fiber, a high SN ratio, and the reduction of costs and the size thereof.
