[0002] At present, single-fiber bidirectional communication technology has been widely used in the field of optical communication. As the core component of single-fiber bidirectional optical communication --- optical transceiver integrated single-fiber bidirectional device also has a variety of design schemes, usually optical transceiver integrated The single-fiber bidirectional device has a square bracket, and the ferrule seat with the ceramic ferrule is installed in the square bracket. The transmitting light hole and the receiving light hole are set in different directions of the square bracket, and the laser and the light receiving detector are installed respectively. The square bracket It is also necessary to set a 45-degree beam splitter and a 0-degree filter on the optical path inside, but in most solutions, the 45-degree beam splitter and the 0-degree filter are fixed on a square bracket or a detector. Disadvantages such as high production process difficulty, complex receiving optical path, difficult control of receiving sensitivity, etc.
