摘要	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.
其他摘要	光学收发器配备有至少一个耦合透镜，其耦合来自光学介质的接收信号光并将传输信号光会聚到光学介质，光学板传递接收信号光并反射传输信号光，光接收元件接收通过光学板的接收信号光，和发射传输信号光以便被光学板反射的发光元件，其中发光元件的发射信号光的发射端口布置在使得来自发光元件的透射信号光能够通过光学在光学介质中形成图像的位置板和耦合透镜，其中发光元件的发射信号光的发射端口布置在使得由光传输的透射信号光的光束中心线形成在光学板上的入射角的方向上发射元件大于光束中心线的入射角，用于最大限度地将来自发光元件的传输信号光会聚到光学介质，以便使来自发光元件的传输信号光的光束中心线远离光线移动接收元件，由此可以减少光学中从发光元件到光接收元件的近端串扰收发器。
