Abstract: The article first introduces TDMA (Time Division Multiple Access) and optical fiber transmission principles,followed by its application in the airborne data acquisition system for detailed study.Based on this work,by using field programmable gate array (FPGA) hardware design,and by designing and implementing the proposed program in hardware part,we designed a FC (Fiber Channel)-based,optical signal transmission and multi-node distributed system.In the actual verification,the experimental results achieved the expected goals,indicating that the design is stable and reliable.
