| Abstract: | Objective To design a FPGA （Field＇Programmable Gate Array）-based image ＆ voice signal optical transmission system, which can accomplish video ＆ audio frequency long-distance transmission. Methods FPGA was used as the main processing chip. High speed transceiver TLK2501 and SFP optical module were also used to realize high-speed serial fiber transmission. Results A non-compressed digital video optical fiber transmission system based on the TDM technology was designed. Conclusion The system achieves the real-time transmission of video and voice signals, thus greatly improving the accuracy of the examination and providing references for diagnostic experts. |
