Abstract:
An optical transmitter-receiver module having a light-emitting element for emitting transmission signal light and a light-receiving element for receiving reception signal light, said module being able to perform both transmission of the transmission signal light and reception of the reception signal light by means of a single-core optical fiber, said module comprising:a jack section for detachably holding an optical plug provided at an end portion of the optical fiber; a light emitting/receiving unit having the light-emitting element and light-receiving element positioned and fixed in place and molded in one piece; and a light-tight partition plate unit for separating an optical path of the transmission signal light and an optical path of the reception signal light from each other, said light-tight partition plate being arranged so as to be held between the jack section and the light emitting/receiving unit, the light-emitting element being located at a larger distance in a direction of optical axis of the optical fiber from an end surface of the optical fiber than the light-receiving element is.
