Abstract
The invention belongs to the technical field of laser communication and relates to a compact wavelength division multiplexing light receiving/emitting integrated single fiber bi-directional device for optical communication. The compact wavelength division multiplexing light receiving/emitting integrated single fiber bi-directional device comprises a metal base; a longitudinal main light path hole is formed in the metal base; a tail fiber is connected to the rear end of the main light path hole; a laser hole and a detector hole, both perpendicular to the main light path hole, are formed in the front section and the rear section of the main light path hole at the same side; a laser and a detector are inserted in the laser hole and the detector hole, respectively; a total-reflection beam splitter and an optical filter corresponding to the laser and the detector in position are arranged in the center of the main light path hole, respectively. As the total-reflection beam splitter is adopted by the compact wavelength division multiplexing light receiving/emitting integrated single fiber bi-directional device, compared with a traditional device structure, the light path direction of the emitting laser of the single fiber bi-directional device is changed by 90 degrees, and therefore, the single fiber bi-directional device, if applied to BOB, is simple to assemble and free from radio frequency matching for emission, and can be manufactured into a pluggable pin which is convenient to repair; if the single fiber bi-directional device is applied to a high-speed device, the single fiber bi-directional device is capable of saving the cost, improving the reliability, reducing the assembly difficult and reducing the volume.
