All-optical transmission is an important development direction of communication technologies in digital radar system. The optical module is the key components part of all-optical transmission, whose research focus on small and high-speed field. In this paper, we elaborated the principle of the miniaturization of two-fiber high speed optical module and the specific implementation of the circuit. Then we illustrated the stabilization of the output optical power, and the extinction ratio control method. Moreover, through the use of non-mortise developed miniaturized optical devices technology, we used muhilayer rigid board and optimized the design of the product casing structure. Finally, a miniaturized dual-fiber high-speed optical module were developed successfully. The performance of parameters meets the design requirements through measurement and real applications.
