Abstract
In an optical transmitter-receiver module for performing optical transmission and reception by using a single-core optical fiber, a light-tight partition plate unit for separation between an optical path of a transmission signal light and an optical path of a reception signal light is held between a jack section for detachably holding an optical plug and a light emitting/receiving unit which has an LED and a PD positioned and fixed in place and molded in one piece. The LED is located at a larger a distance in a direction of optical axis from the optical fiber than the PD is. The partition plate unit is urged toward the optical fiber by springs.
