Abstract：In order to ensure that the external system equivalent can carry out a comprehensive high-speed and reliable perfor-mance test on the aircraft and other aircraft during the research and development test stage,the traditional transmission mode can no longer meet the requirements of high-speed data transmission,and the optical fiber with its advantages of large capacity,wide band and strong anti-interference makes it play an increasingly important role in data transmission[1].According to the requirements of the project,FPGA is designed as the main control,optical module as the data transmission core,and it is connected to the host comput-er through Ethernet to realize the data configuration instructions and the transmission and receiving of analog data.After high and low temperature and vibration tests,it is shown that the circuit runs stably and can successfully transmit optical signals to the mea-suring equipment at a rate of 2.5 Gbps.No leakage,leakage,repeated acquisition or repeated transmission is observed.It has been applied to a certain type of external system equivalent.
