An optical transceiver is equipped with at least one coupling lens which condenses reception signal light from an optical medium and condenses transmission signal light to the optical medium, an optical plate which passes the reception signal light and reflects the transmission signal light, a light receiving element which receives the reception signal light passed through the optical plate, and a light emitting element which transmits the transmission signal light so as to be reflected by the optical plate, wherein an emission port of the transmission signal light of the light emitting element is arranged at a position to enable the transmission signal light from the light emitting element to form an image in the optical medium via the optical plate and the coupling lens, and wherein the emission port of the transmission signal light of the light emitting element is arranged in a direction that makes the incident angle formed on the optical plate by the beam center line of the transmission signal light transmitted from the light emitting element larger than the incident angle of the beam center line for maximally condensing the transmission signal light from the light emitting element to the optical medium in order to move the beam center line of the transmission signal light from the light emitting element away from the light receiving element, whereby it becomes possible to reduce the near-end crosstalk from the light emitting element to the light receiving element in the optical transceiver.
